get all values of columns in sql php [duplicate] - php

I want to retrieve the values from a database table and show them in a html table in a page.
I already searched for this but I couldn't find the answer, although this surely is something easy (this should be the basics of databases lol). I guess the terms I've searched are misleading.
The database table name is tickets, it has 6 fields right now (submission_id, formID, IP, name, email and message) but should have another field called ticket_number.
How can I get it to show all the values from the db in a html table like this:
<table border="1">
<tr>
<th>Submission ID</th>
<th>Form ID</th>
<th>IP</th>
<th>Name</th>
<th>E-mail</th>
<th>Message</th>
</tr>
<tr>
<td>123456789</td>
<td>12345</td>
<td>123.555.789</td>
<td>John Johnny</td>
<td>johnny#example.com</td>
<td>This is the message John sent you</td>
</tr>
</table>
And then all the other values below 'john'.

$con=mysqli_connect("example.com","peter","abc123","my_db");

$result = mysqli_query($con,"SELECT * FROM Persons");

Here is an easy way to fetch data from a MySQL database using PDO.
define("DB_HOST", "localhost"); // Using Constants
define("DB_USER", "YourUsername");
define("DB_PASS", "YourPassword");
define("DB_NAME", "Yourdbname");
$dbc = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME.";charset-utf8mb4", DB_USER, DB_PASS);
$print = ""; // assign an empty string
$stmt = $dbc->query("SELECT * FROM tableName"); // fetch data
$stmt->setFetchMode(PDO::FETCH_OBJ);
$print .= '<table border="1px">';
$print .= '<tr><th>First name</th>';
$print .= '<th>Last name</th></tr>';
while ($names = $stmt->fetch()) { // loop and display data
$print .= '<tr>';
$print .= "<td>{$names->firstname}</td>";
$print .= "<td>{$names->lastname}</td>";
$print .= '</tr>';
}
$print .= "</table>";
echo $print;

First, start a connection to the database. Do this by making all the string variables needed in order to connect, adjusting them to fit your environment, then creating a new connection object with new mysqli() and initializing it with the previously made variables as its parameters. Now, check the connection for errors and display a message whether any were found or not. Like this:
<?php
$servername = "localhost";
$username = "root";
$password = "yourPassword";
$database = "world";
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$conn = new mysqli($servername, $username, $password, $database);
echo "Connected successfully<br>";
?>
Next, make a variable that will hold the query as a string, in this case its a select statement with a limit of 100 records to keep the list small. Then, we can execute it by calling the mysqli::query() function from our connection object. Now, it's time to display some data. Start by opening up a <table> tag through echo, then fetch one row at a time in the form of a numerical array with mysqli::fetch_row() which can then be displayed with a simple for loop. mysqli::field_count should be self explanatory. Don't forget to use <td></td> for each value, and also to open and close each row with echo"<tr>" and echo"</tr>. Finally we close the table, and the connection as well with mysqli::close().
<?php
$query = "select * from city limit 100;";
$queryResult = $conn->query($query);
echo "<table>";
while ($queryRow = $queryResult->fetch_row()) {
echo "<tr>";
for($i = 0; $i < $queryResult->field_count; $i++){
echo "<td>$queryRow[$i]</td>";
}
echo "</tr>";
}
echo "</table>";
$conn->close();
?>

First, connect to the database:
$conn=mysql_connect("hostname","username","password");
mysql_select_db("databasename",$conn);
You can use this to display a single record:
For example, if the URL was /index.php?sequence=123, the code below would select from the table, where the sequence = 123.
<?php
$sql="SELECT * from table where sequence = '".$_GET["sequence"]."' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
$result=mysql_fetch_array($rs);
echo '<table>
<tr>
<td>Forename</td>
<td>Surname</td>
</tr>
<tr>
<td>'.$result["forename"].'</td>
<td>'.$result["surname"].'</td>
</tr>
</table>';
?>
Or, if you want to list all values that match the criteria in a table:
<?php
echo '<table>
<tr>
<td>Forename</td>
<td>Surname</td>
</tr>';
$sql="SELECT * from table where sequence = '".$_GET["sequence"]."' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
while($result=mysql_fetch_array($rs))
{
echo '<tr>
<td>'.$result["forename"].'</td>
<td>'.$result["surname"].'</td>
</tr>';
}
echo '</table>';
?>

Surely a better solution would by dynamic so that it would work for any query without having to know the column names?
If so, try this (obviously the query should match your database):
// You'll need to put your db connection details in here.
$conn = new mysqli($server_hostname, $server_username, $server_password, $server_database);
// Run the query.
$result = $conn->query("SELECT * FROM table LIMIT 10");
// Get the result in to a more usable format.
$query = array();
while($query[] = mysqli_fetch_assoc($result));
array_pop($query);
// Output a dynamic table of the results with column headings.
echo '<table border="1">';
echo '<tr>';
foreach($query[0] as $key => $value) {
echo '<td>';
echo $key;
echo '</td>';
}
echo '</tr>';
foreach($query as $row) {
echo '<tr>';
foreach($row as $column) {
echo '<td>';
echo $column;
echo '</td>';
}
echo '</tr>';
}
echo '</table>';
Taken from here: https://www.antropy.co.uk/blog/handy-php-snippets/

mysql_connect("localhost","root","");
mysql_select_db("database");
$query=mysql_query("select * from studenti");
$x=#mysql_num_rows($query);
echo "<a href='file.html'>back</a>";
echo "<table>";
$y=mysql_num_fields($query);
echo "<tr>";
for($i=0 ,$i<$y,$i++)
{
$values=mysql_field_name($query,$i);
echo "<th>$values</th>";
}
echo "</tr>";
while(list($p ,$n $your_table_list)=mysql_fetch_row($query))
{
print("<tr>\n".
"<td>$p</td>".
"</tr>/n");
}
?>

<?php
$mysql_hostname = "localhost";
$mysql_user = "ram";
$mysql_password = "ram";
$mysql_database = "mydb";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Oops some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Oops some thing went wrong");// we are now connected to database
$result = mysql_query("SELECT * FROM users"); // selecting data through mysql_query()
echo '<table border=1px>'; // opening table tag
echo'<th>No</th><th>Username</th><th>Password</th><th>Email</th>'; //table headers
while($data = mysql_fetch_array($result))
{
// we are running a while loop to print all the rows in a table
echo'<tr>'; // printing table row
echo '<td>'.$data['id'].'</td><td>'.$data['username'].'</td><td>'.$data['password'].'</td><td>'.$data['email'].'</td>'; // we are looping all data to be printed till last row in the table
echo'</tr>'; // closing table row
}
echo '</table>'; //closing table tag
?>
it would print the table like this
just read line by line so that you can understand it easily..

OOP Style :
At first connection with database.
<?php
class database
{
public $host = "localhost";
public $user = "root";
public $pass = "";
public $db = "db";
public $link;
public function __construct()
{
$this->connect();
}
private function connect()
{
$this->link = new mysqli($this->host, $this->user, $this->pass, $this->db);
return $this->link;
}
public function select($query)
{
$result = $this->link->query($query) or die($this->link->error.__LINE__);
if($result->num_rows>0)
{
return $result;
}
else
{
return false;
}
}
?>
Then :
<?php
$db = new database();
$query = "select * from data";
$result = $db->select($query);
echo "<table>";
echo "<tr>";
echo "<th>Name </th>";
echo "<th>Roll </th>";
echo "</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td> $row[name]</td>";
echo "<td> $row[roll]</td>";
echo "</tr>";
}
echo "</table>";
?>

Creating dynamic tables in HTML using MySQL and PHP

I've seen many posts about how to build a table in HTML with PHP and MysSQL, but I often change the headers of MySQL columns after creating a table.
Is there any way for PHP to update the code automatically so that I can just put in the table name and it prints the table without me having to put in all the <th> tags?
<?php
$table = "user";
$database = "database";
$conn = mysqli_connect("localhost", "username", "password", "database", "3306");
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM $table";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) {
echo "<tr><td>" . $row["id"] . "</td><td>" . $row["first_name"] . "</td><td>" . $row["last_name"] . "</td><td>" . $row["birthday"] . "</td></tr>";
}
echo "</table>";
} else {
echo "0 result";
}
$conn->close();
If you want to display the full contents of the database table as an HTML table, I suggest you make a function that will do all of this dynamically for you. This function should check that the table exists, fetch all the data, and fetch output HTML table with headers.
MySQLi solution
Here is my suggestion using MySQLi. First of all, you must make sure that the table actually exists. Then you can fetch all the data from the table. The object returned by mysqli::query() will have all metadata information about column names which you can use to display the header row. You can use fetch_fields() to iterate over each column metadata. The data can be fetched using fetch_all() method.
<?php
// create global connection using mysqli
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$conn = mysqli_connect("localhost", "username", "password", "database", "3306");
$mysqli->set_charset('utf8mb4'); // always set the charset
function outputMySQLToHTMLTable(mysqli $mysqli, string $table)
{
// Make sure that the table exists in the current database!
$tableNames = array_column($mysqli->query('SHOW TABLES')->fetch_all(), 0);
if (!in_array($table, $tableNames, true)) {
throw new UnexpectedValueException('Unknown table name provided!');
}
$res = $mysqli->query('SELECT * FROM '.$table);
$data = $res->fetch_all(MYSQLI_ASSOC);
echo '<table>';
// Display table header
echo '<thead>';
echo '<tr>';
foreach ($res->fetch_fields() as $column) {
echo '<th>'.htmlspecialchars($column->name).'</th>';
}
echo '</tr>';
echo '</thead>';
// If there is data then display each row
if ($data) {
foreach ($data as $row) {
echo '<tr>';
foreach ($row as $cell) {
echo '<td>'.htmlspecialchars($cell).'</td>';
}
echo '</tr>';
}
} else {
echo '<tr><td colspan="'.$res->field_count.'">No records in the table!</td></tr>';
}
echo '</table>';
}
outputMySQLToHTMLTable($mysqli, 'user');
PDO Solution
Using PDO is very similar but you have to pay attention to the differences in the APIs.
To get the table names, you can use fetchAll(PDO::FETCH_COLUMN) instead of array_column(). To get the column metadata, you need to use getColumnMeta() function.
<?php
$pdo = new PDO("mysql:host=localhost;dbname=test;charset=utf8mb4", 'username', 'password', [
\PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
\PDO::ATTR_EMULATE_PREPARES => false
]);
function outputMySQLToHTMLTable(pdo $pdo, string $table)
{
// Make sure that the table exists in the current database!
$tableNames = $pdo->query('SHOW TABLES')->fetchAll(PDO::FETCH_COLUMN);
if (!in_array($table, $tableNames, true)) {
throw new UnexpectedValueException('Unknown table name provided!');
}
$stmt = $pdo->query('SELECT * FROM '.$table);
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
$columnCount = $stmt->columnCount();
echo '<table>';
// Display table header
echo '<thead>';
echo '<tr>';
for ($i = 0; $i < $columnCount; $i++) {
echo '<th>'.htmlspecialchars($stmt->getColumnMeta($i)['name']).'</th>';
}
echo '</tr>';
echo '</thead>';
// If there is data then display each row
if ($data) {
foreach ($data as $row) {
echo '<tr>';
foreach ($row as $cell) {
echo '<td>'.htmlspecialchars($cell).'</td>';
}
echo '</tr>';
}
} else {
echo '<tr><td colspan="'.$columnCount.'">No records in the table!</td></tr>';
}
echo '</table>';
}
outputMySQLToHTMLTable($pdo, 'user');
P.S. The table existence check can be optimized with the following code instead:
$tableNames = $pdo->prepare('SELECT COUNT(1) FROM information_schema.TABLES WHERE TABLE_SCHEMA = SCHEMA() AND TABLE_NAME=?');
$tableNames->execute([$table]);
if (!$tableNames->fetchColumn()) {
throw new UnexpectedValueException('Unknown table name provided!');
}
I just read your question, and coded to meet your needs, but I used PDO and not MYSQLI, maybe it is better for you to understand the code, because with PDO everything is simpler. And the way I did it, you don't need to put all the tags, PHP will update automatically, and know that the file must end with the extension .php!
<?php
$conn = new PDO("mysql:host=localhost;dbname=YOUR_DATABASE_HERE", "USERNAME", "PASSWORD");
if(!$conn){
echo "Could not connect!";
}
?>

PHP and MySQL WP

I am trying to accomplish two things here with this code. I am writing PHP directly into a WP page using the INSERT PHP Plugin.
1) Query the MySQL database and return the results from one column into four columns.
2) Make each result is its own hyperlink that directs the user to a new WP page that runs a new query on that page.
I am able to get the query to show results and even to turn those results into a dynamic hyperlink, however I cannot get the formatting down. Right now it just returns the result into one column. Here is what I have:
[insert_php]
$servername = "localhost";
$username = "login"; //edited for privacy
$password = "password"; //edited for privacy
$database = "database"; //edited for privacy
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
//get results from database
$result = mysqli_query($conn,"SELECT mine FROM mines ORDER BY mine");
$all_property = array(); //declare an array for saving property
//showing property
echo '<table class="data-table">
<tr class="data-heading">'; //initialize table tag
while ($property = mysqli_fetch_field($result)) {
echo '<td>' . $property->name . '</td>'; //get field name for header
array_push($all_property, $property->name); //save those to array
}
echo '</tr>'; //end tr tag
//showing all data
while ($row = mysqli_fetch_array($result)) {
echo "<tr>";
foreach ($all_property as $item) {
echo "<td><a href='urlhere/$row[$item]'>".$row[$item]. "</a>"."</td>"; //get items using property value
}
echo '</tr>';
}
echo "</table>";
[/insert_php]
Thanks for any help you can offer.
I'd like the results to look like this (each one as a hyperlink):
Image link below
I was able to work this out. Still have not gotten the results to properly hyperlink but the array is filling in over four columns now. Here is my code:
$sql = "SELECT mine FROM mines ORDER by mine";
$result = mysqli_query($conn, $sql);
if ($result) {
$data = array();
while($row = $result->fetch_assoc()) {
$data[] = $row['mine'];
}
}
if (is_array($data) && count($data)) { // if array's not empty, create HTML
//create a table & header row
$htmlout="<table><tr>
<th colspan='4'>Mine</th></tr>
<tr>
";
$counter = 1; //keep count of data
foreach ($data as $mines) {
//table cell for datum
$htmlout .= "<td>$mines</td>\n";
//rows of 4
if ($counter % 4 == 0) {
$htmlout .= "</tr>\n<tr>\n";
}
$counter++;
}
}
$htmlout .= "</tr></table>";
echo $htmlout;

How to use database table header for html <th> table header tag

I'm new to PHP. I use the code (below) to print a MySQL table as an HTML table.
However my code prints the table headers from the database.
How can I print HTML table header in hard coded format using the <th>header</th> tags and print the all rows from the table?
Thanks!
<?php
$db_host = 'localhost';
$db_user = 'my user';
$db_pwd = 'my pwd';
$database = 'my db';
$table = 'subcontractor';
if (!mysql_connect($db_host, $db_user, $db_pwd))
die("Can't connect to database");
if (!mysql_select_db($database))
die("Can't select database");
// sending query
$result = mysql_query("SELECT * FROM {$table}");
if (!$result) {
die("Query to show fields from table failed");
}
$fields_num = mysql_num_fields($result);
echo "<table class='table table-bordered table-striped mb-none' id='datatable-tabletools' data-swf-path='assets/vendor/jquery-datatables/extras/TableTools/swf/copy_csv_xls_pdf.swf' >";
// printing table headers
echo "<thead>";
for($i=0; $i<$fields_num; $i++)
{
$field = mysql_fetch_field($result);
echo "<th>{$field->name}</th>";
}
echo "</thead>";
// printing table rows
while($row = mysql_fetch_row($result))
{
echo "<tbody>";
echo "<tr>";
echo "</thead>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";
echo "</tr>";
echo "</tbody>";
}
mysql_free_result($result);
?>
Thank you works perfect. Is there a way to make PHP skip a column from the table on the DB? Thanks –
Yes, just change the Query
$result = mysql_query("SELECT * FROM {$table}");
for example by
$result = mysql_query("SELECT `name`,`email`,`address` FROM {$table}");
You can change the headers by removing these lines of code.
for($i=0; $i<$fields_num; $i++)
{
$field = mysql_fetch_field($result);
echo "<th>{$field->name}</th>";
}
Replace the above lines for example by:
echo "<thead>";
echo "<th>My Header 1</th>";
echo "<th>My Header 2</th>";
echo "</thead>";

Surely a better solution would by dynamic so that it would work for any query without having to know the column names?
If so, try this (obviously the query should match your database):
// You'll need to put your db connection details in here.
$conn = new mysqli($server_hostname, $server_username, $server_password, $server_database);
// Run the query.
$result = $conn->query("SELECT * FROM table LIMIT 10");
// Get the result in to a more usable format.
$query = array();
while($query[] = mysqli_fetch_assoc($result));
array_pop($query);
// Output a dynamic table of the results with column headings.
echo '<table border="1">';
echo '<tr>';
foreach($query[0] as $key => $value) {
echo '<td>';
echo $key;
echo '</td>';
}
echo '</tr>';
foreach($query as $row) {
echo '<tr>';
foreach($row as $column) {
echo '<td>';
echo $column;
echo '</td>';
}
echo '</tr>';
}
echo '</table>';

mysql_connect("localhost","root","");
mysql_select_db("database");
$query=mysql_query("select * from studenti");
$x=#mysql_num_rows($query);
echo "<a href='file.html'>back</a>";
echo "<table>";
$y=mysql_num_fields($query);
echo "<tr>";
for($i=0 ,$i<$y,$i++)
{
$values=mysql_field_name($query,$i);
echo "<th>$values</th>";
}
echo "</tr>";
while(list($p ,$n $your_table_list)=mysql_fetch_row($query))

<?php
$mysql_hostname = "localhost";
$mysql_user = "ram";
$mysql_password = "ram";
$mysql_database = "mydb";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Oops some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Oops some thing went wrong");// we are now connected to database
$result = mysql_query("SELECT * FROM users"); // selecting data through mysql_query()
echo '<table border=1px>'; // opening table tag
echo'<th>No</th><th>Username</th><th>Password</th><th>Email</th>'; //table headers
while($data = mysql_fetch_array($result))
{
// we are running a while loop to print all the rows in a table
echo'<tr>'; // printing table row
echo '<td>'.$data['id'].'</td><td>'.$data['username'].'</td><td>'.$data['password'].'</td><td>'.$data['email'].'</td>'; // we are looping all data to be printed till last row in the table
echo'</tr>'; // closing table row
}
echo '</table>'; //closing table tag
?>
it would print the table like this
just read line by line so that you can understand it easily..
OOP Style :
At first connection with database.
<?php
class database
{
public $host = "localhost";
public $user = "root";
public $pass = "";
public $db = "db";
public $link;
public function __construct()
{
$this->connect();
}
private function connect()
{
$this->link = new mysqli($this->host, $this->user, $this->pass, $this->db);
return $this->link;
}
public function select($query)
{
$result = $this->link->query($query) or die($this->link->error.__LINE__);
if($result->num_rows>0)
{
return $result;
}
else
{
return false;
}
}
?>
Then :
<?php
$db = new database();
$query = "select * from data";
$result = $db->select($query);
echo "<table>";
echo "<tr>";
echo "<th>Name </th>";
echo "<th>Roll </th>";
echo "</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td> $row[name]</td>";
echo "<td> $row[roll]</td>";
echo "</tr>";
}
echo "</table>";
?>

Displaying all records in a mysql table

The code below works fine for printing one record from a database table, but what I really want to be able to do is print all the records in the mysql table in a format similar to my code.
I.E.: Field Name as heading for each column in the html table and the entry below the heading. Hope this is making sense to someone ;)
$raw = mysql_query("SELECT * FROM tbl_gas_meters");
$allresults = mysql_fetch_array($raw);
$field = mysql_query("SELECT * FROM tbl_gas_meters");
$num_fields = mysql_num_fields($raw);
$num_rows = mysql_num_rows($raw);
$i = 1;
print "<table border=1>\n";
while ($i < $num_fields)
{
echo "<tr>";
echo "<b><td>" . mysql_field_name($field, $i) . "</td></b>";
//echo ": ";
echo '<td><font color ="red">' . $allresults[$i] . '</font></td>';
$i++;
echo "</tr>";
//echo "<br>";
}
print "</table>";
Just as an additional piece of information you should probably be using PDO. It has more features and is helpful in learning how to prepare SQL statements. It will also serve you much better if you ever write more complicated code.
http://www.php.net/manual/en/intro.pdo.php
This example uses objects rather then arrays. Doesn't necessarily matter, but it uses less characters so I like it. Difference do present themselves when you get deeper into objects, but not in this example.
//connection information
$user = "your_mysql_user";
$pass = "your_mysql_user_pass";
$dbh = new PDO('mysql:host=your_hostname;dbname=your_db;charset=UTF-8', $user, $pass);
//prepare statement to query table
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
//loop over all table rows and fetch them as an object
while($result = $sth->fetch(PDO::FETCH_OBJ))
{
//print out the fruits name in this case.
print $result->name;
print("\n");
print $result->colour;
print("\n");
}
You probably also want to look into prepared statements. This helps against injection. Injection is bad for security reasons. Here is the page for that.
http://www.php.net/manual/en/pdostatement.bindparam.php
You probably should look into sanitizing your user input as well. Just a heads up and unrelated to your current situation.
Also to get all the field names with PDO try this
$q = $dbh->prepare("DESCRIBE tablename");
$q->execute();
$table_fields = $q->fetchAll(PDO::FETCH_COLUMN);
Once you have all the table fields it would be pretty easy using <div> or even a <table> to arrange them as you like using a <th>
Happy learning PHP. It is fun.
Thanks guys, got it.
$table = 'tbl_gas_meters';
$result = MYSQL_QUERY("SELECT * FROM {$table}");
$fields_num = MYSQL_NUM_FIELDS($result);
ECHO "<h1>Table: {$table}</h1>";
ECHO "<table border='1'><tr>";
// printing table headers
FOR($i=0; $i<$fields_num; $i++)
{
$field = MYSQL_FETCH_FIELD($result);
ECHO "<td>{$field->name}</td>";
}
ECHO "</tr>\n";
// printing table rows
WHILE($row = MYSQL_FETCH_ROW($result))
{
ECHO "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
FOREACH($row AS $cell)
ECHO "<td>$cell</td>";
ECHO "</tr>\n";
}
while ( $row = mysql_fetch_array($field) ) {
echo $row['fieldname'];
//stuff
}
Try this :
$raw = mysql_query("SELECT * FROM tbl_gas_meters");
$allresults = mysql_fetch_array($raw);
$field = mysql_query("SELECT * FROM tbl_gas_meters");
while($row = mysql_fetch_assoc($field)){
echo $row['your field name here'];
}
Please note that, mysql_* functions are deprecated in new php version , so use mysqli or PDO instead.
Thanks! I adapted some of these answers to draw a table from all records from any table, without having to specify the field names. Just paste this into a .php file and change the connection info:
<?php
// Authentication detail for connection
$servername = "localhost";
$username = "xxxxxxxxxx";
$password = "xxxxxxxxxx";
$dbname = "xxxxxxxxxx";
$tablename = "xxxxxxxxxx";
$orderby = "1 DESC LIMIT 500"; // column # to sort & max # of records to display
// Create & check connection
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error); // quit
}
// Run query & verify success
$sql = "SELECT * FROM {$tablename} ORDER BY {$orderby}";
if ($result = $conn->query($sql)) {
$conn->close(); // Close table
$fields_num = $result->field_count;
$count_rows = $result->num_rows;
if ($count_rows == 0) {
die ("No data found in table: [" . $tablename . "]" ); //quit
}
} else {
$conn->close(); // Close table
die ("Error running SQL:<br>" . $sql ); //quit
}
// Start drawing table
echo "<!DOCTYPE html><html><head><title>{$tablename}</title>";
echo "<style> table, th, td { border: 1px solid black; border-collapse: collapse; }</style></head>";
echo "<body><span style='font-size:18px'>Table: <strong>{$tablename}</strong></span><br>";
echo "<span style='font-size:10px'>({$count_rows} records, {$fields_num} fields)</span><br>";
echo "<br><span style='font-size:10px'><table><tr>";
// Print table Field Names
while ($finfo = $result->fetch_field()) {
echo "<td><center><strong>{$finfo->name}</strong></center></td>";
}
echo "</tr>"; // Finished Field Names
/* Loop through records in object array */
while ($row = $result->fetch_row()) {
echo "<tr>"; // start data row
for( $i = 0; $i<$fields_num; $i++ ) {
echo "<td>{$row[$i]}</td>";
}
echo "</tr>"; // end data row
}
echo "</table>"; // End table
$result->close(); // Free result set
?>
