PDO combine table headers with data - php

I am getting the name of the database table heads and data like this:
/* Get column names */
public function get_head($table)
{
$this->table = $table;
$query = $this->conn->prepare("DESCRIBE ".$this->table);
$query->execute();
return $query->fetchAll(PDO::FETCH_COLUMN);
}
/* List all users */
public function get_users($table)
{
$this->table = $table;
$query = $this->conn->prepare("SELECT * FROM ".$this->table);
$query->execute();
return $query->fetchAll();
}
and they are output like this:
<table border=1>
<?php
// Get headers
$columns = $user->get_head('login');
foreach ($columns as $col)
{
echo '<th>'.$col.'</th>';
}
// Get users
$users = $user->get_users('login');
foreach ($users as $user)
{
echo '<tr>';
echo '<td>'.$user['user_id'].'. </td>';
echo '<td>'.$user['user_name'].'</td>';
echo '<td>'.$user['email'].'</td>';
echo '<td>'.$user['password'].'</td>';
echo '<td>'.$user['role'].'</td>';
echo '<td>'.$user['last_login_date'].'</td>';
echo '<td>'.$user['date_created'].'</td>';
echo '<td>'.$user['status'].'</td>';
echo '</tr>';
}
?>
How can I write the second foreach to generate the data automatically based on the names output by the first foreach of the table headers?

In your code where you want to show the data for each row, you can foreach() over the $columns and use the column name as the index to your user data...
echo '<tr>';
foreach ( $columns as $column ) {
echo '<td>'.$user[$column].'</td>';
}
echo '</tr>';

PHP code to separate Table based on column values

I have a csv file that should be converted to HTML table based on column values , and I have to put the values into separate table based on first column of csv . And I think the problem is because of '\n' in first column.
So its like this:
Here in Result column, in one row I have three values separated using comma (W,M,P). In the code I wrote it is considered as separate table headers .
Can anyone please help me with this?
This is my code:
<?php
$csv="FinalResult.csv" ;
$csvcontents=file_get_contents($csv);
$csv_array = explode("\n", $csvcontents);
$tables = [];
foreach($csv_array as $key => $value) {
if ($key == 0) {
continue;
}
$line = explode(',', $value);
if (array_key_exists($line[0], $tables)) {
$tables[$line[0]][] = $line;
} else {
$tables[$line[0]] = [$line];
}
}
foreach ($tables as $key => $value) {
echo '<h1> ' .$key. ' </h1>'; // YOUR TITLE (Team)
echo "<table>";
echo '<tr>';
foreach (explode(',', $csv_array[0]) as $keyHeader => $valueHeader) {
if (in_array($keyHeader, [0, 1])) {
continue;
}
echo "<th>$valueHeader</th>";
}
echo '</tr>';
foreach ($value as $keyRow => $valueRow) {
echo '<tr>';
foreach ($valueRow as $keyValue => $valueValue) {
if (in_array($keyValue, [0, 1])) {
continue;
}
echo "<td>$valueValue</td>";
}
echo '</tr>';
}
echo '</table>';
}
?>
I refereed in stack overflow , but there they were giving only single values to a column and not providing multiple values .
But am getting output like this ,
so it takes the value of Result column after '-' as a new heading , i tried but am not able to solve this , can anyone really help me in this matter .
Here is how my output should look like:
I marked in yellow where all the data am getting in same column
This is my csv file :
Team,Date,Opponent,Result
MIN,May-03,UTA,a.b.c=d-e.f-g.h=log4j2-i.xml-j -k -a4j.k=tp_r-RR.xml -
MIN,May-04,SEA,"L,Q,J"
SAC,May-03,DAL,L
SAC,May-04,TOR,W
NYN,May-05,BAL,L
NYN,May-07,MIA,W
Here is the code
<table>
<?php
$csvValues= array_map('str_getcsv', file('FinalResult.csv'));
$counter = 0;
// Header
echo "<tr>";
foreach($csvValues[0] as $headers){
echo "<th>".$headers."</th>";
}
echo "</tr>";
// Content
foreach($csvValues as $values){
echo "<tr>";
if($counter >0){
foreach($values as $data){
echo "<td>".$data."</td>";
}
}
echo "</tr>";
$counter++;
}
?>
</table>

identifying column number in PHP mysqli_fetch_row() WHILE loop

I'm trying to identify whether I am looking at the first column in the array.
I haven't tried anything, but googled plenty and cannot find a solution.
while($row = mysqli_fetch_row($sql)) {
echo '<tr>';
foreach ($row as $col) {
if () //NEED CODE HERE
echo "<td><a href = 'https://whatismyipaddress.com/ip-lookup' target = '_blank'>$col</a></td>";
}
echo '</tr>';
}
mysqli_fetch_row fetches "one row of data from the result set and returns it as an enumerated array, where each column is stored in an array offset starting from 0 (zero)." So the key of the column is the same as column order.
So you can do this:
while($row = mysqli_fetch_row($sql)) {
echo '<tr>';
foreach ($row as $key => $col) {
if ($key === 0) {
echo "<td><a href = 'https://whatismyipaddress.com/ip-lookup' target = '_blank'>$col</a></td>";
}
}
echo '</tr>';
}
But column is subjected to changes in database structure and SQL query changes. I would personally prefer mysqli_fetch_assoc or mysqli_fetch_object so I can use the column by name instead of order number. Its less error prone. For example,
while($row = mysqli_fetch_assoc($sql)) {
echo '<tr>';
foreach ($row as $key => $col) {
if ($key === 'ip_address') {
echo "<td><a href = 'https://whatismyipaddress.com/ip-lookup' target = '_blank'>$col</a></td>";
}
}
echo '</tr>';
}
Note: $sql here should be a mysqli_query result instead of the actual SQL string.

How can I re-organize php array of sports

I'm trying to list sport league offerings for intramurals. My current php foreach spits out all the leagues and offerings. Great.
Now I want to only show 1 instance of the sport (course), like "Basketball" and then list the multiple league offerings (offering) in columns.
I can't do another loop based on
if $nt['course'] == "Basketball" because these will change
Not sure if my mssql query needs to change or if I can use another foreach loop?
query
$sql2 = SELECT category
,course
,offering
,Semester
,spots
,registerLink from dbtable WHERE semester like "%Fall 2016%" and category like "%Leagues%" ORDER BY course
$rs= mssql_query ($sql2, $con)
or die("Error!");
$result = array();
if (mssql_num_rows($rs)) {
while ($row = mssql_fetch_assoc($rs)) {
$result[] = $row;
}
}
return $result;
exit();
my foreach loop in view:
<?php
foreach ($data as $nt) {
echo "<div class='col-md-2'>";
echo "<h2><a href='#'>".$nt['course']."</a></h2>";
echo "<h3>".$nt['offering']."</h3>";
echo "<h4>".$nt['Semester']."</h4>";
echo "<p>".$nt['spots']."</p>";
echo "<button>".$nt['registerLink']."</button>";
echo "</div>";
}
So just to clarify:
category = "Leagues" which is in my query
course = Basketball and Flag Football, etc
It's very simple:-
instead of
$result[] = $row;
do
$result[ $row['course']][] = $row;
Simple solution:
$result = array();
if (mssql_num_rows($rs)) {
while ($row = mssql_fetch_assoc($rs)) {
if(!in_array($row["course"], $result))
{
array_push($result, $row["course"]);
}
array_push($result[$row["course"]], $row);
}
}
return $result;
And loop in view:
foreach($data as $key => $value)
{
echo "<h1>".$key."</h1>";
foreach($value as $nt)
{
echo "<div class='col-md-2'>";
echo "<h3>".$nt['offering']."</h3>";
echo "<h4>".$nt['Semester']."</h4>";
echo "<p>".$nt['spots']."</p>";
echo "<button>".$nt['registerLink']."</button>";
echo "</div>";
}
}

MYSQLi Multiple Records Outputs Duplicates

Issue:
I've continuously looked over my code and cannot find why the array is duplicating the data. A single entry into the database has a correct output, however if there is more than one it will duplicate those before it as well as the next one.
My Code:
global $connection;
//Query database & retrieve results.
$search = $connection->query('SELECT * FROM users WHERE country= "'.$country.'"');
echo '<table><tr><th>Username</th><th>Email</th><th>Country</th></tr>';
while ($result = $search->fetch_assoc())
{
$total[] = $result;
foreach ($total as $rows)
{
echo '<tr>';
echo '<td>'.stripslashes($rows['username']).'</td>';
echo '<td>'.stripslashes($rows['email']).'</td>';
echo '<td>'.stripslashes($rows['country']).'</td>';
echo '</tr>';
}
}
echo '</table>';
Output:
This will return the following form -
Username Email Country
exampleUser1 exampleEmail1#example.com United States
exampleUser1 exampleEmail1#example.com United States
exampleUser2 exampleEmail2#example.com United States
You can see the first line is repeated then the new entry is there, it will continue on from this the more it goes on.
Additional Info:
This is placed inside of a function and is executed when $_POST['country'] is submitted - $country is just $_POST['country'] with a real_escape_string.
$connection is just a new mysqli(localhost, user, pass, database) referenced in the script - it is globalised because this is wrapped inside a function.
Any help would be appreciated.
<?php
//... Your code
while ($rows = $search->fetch_assoc()) {
$rows = array_map('stripslashes', $rows);
echo '<tr>';
echo '<td>'.$rows['username'].'</td>';
echo '<td>'.$rows['email'].'</td>';
echo '<td>'.$rows['country'].'</td>';
echo '</tr>';
}
//... Your code
if you need to save and return from function this rows just create array $total and add $total[] = $rows; after echo '</tr>';
As mentioned in my comment, put the foreach outside your while loop like this:
echo '<table><tr><th>Username</th><th>Email</th><th>Country</th></tr>';
while ($result = $search->fetch_assoc()) {
$total[] = $result;
}
foreach ($total as $rows) {
echo '<tr>';
echo '<td>'.stripslashes($rows['username']).'</td>';
echo '<td>'.stripslashes($rows['email']).'</td>';
echo '<td>'.stripslashes($rows['country']).'</td>';
echo '</tr>';
}
echo '</table>';
Another solution is to just redeclare your $total all the time.. Just keep your code then and do:
$total = $result;

Displaying an associative array in PHP

I am trying to build a function that extracts information from a database and inserts it into an associative array in PHP using mysql_fetch_assoc, and return the array so another function can display it. I need a way to display the returned assoc array. This should be a different function from the first one
print_r($array) will give nicely formatted (textually, not html) output.
If you just want information about what is in the array (for debugging purposes), you can use print_r($array) or var_dump($array), or var_export($array) to print it in PHP's array format.
If you want nicely formatted output, you might want to do something like:
<table border="1">
<?php
foreach($array as $name => $value) {
echo "<tr><th>".htmlspecialchars($name).
"</th><td>".htmlspecialchars($value)."</th></tr>";
}
?>
</table>
This will, as you might already see, print a nicely formatted table with the names in the left column and the values in the right column.
while ($row = mysql_fetch_assoc($result)) {
foreach ($row as $column => $value) {
//Column name is in $column, value in $value
//do displaying here
}
}
If this is a new program, consider using the mysqli extension instead.
Assuming you've made the call, and got $result back:
$array = new array();
while($row = mysql_fetch_assoc($result)){
$array[] = $row;
}
return $array;
This should get you going:
$rows = mysql_query("select * from whatever");
if ($rows) {
while ($record = mysql_fetch_array($rows)) {
echo $record["column1"];
echo $record["column2"];
// or you could just var_dump($record); to see what came back...
}
}
The following should work:
$rows = mysql_query("select * from whatever");
if ($rows) {
$header = true;
while ($record = mysql_fetch_assoc($rows)) {
if ($header) {
echo '<tr>';
foreach (array_keys($record) AS $col) {
echo '<td>'.htmlspecialchars($col).'</td>';
}
echo '</tr>';
$header = false;
}
echo '<tr>';
foreach (array_values($record) AS $col) {
echo '<td>'.htmlspecialchars($col).'</td>';
}
echo '</tr>';
}
}
(Yes, blatant mod of Fosco's code)
This should print the column headers once, then the contents after that. This would print just whatever columns were retrieved from the DB, regardless of the query.
