PHP: MySQL to table - php

Question

I just wrote simple PHP code that would print some of these rows
That's how does my table structure looks like:
That's my PHP code:
$user = mysql_query("SELECT usr FROM ava_members");
$id = mysql_query("SELECT id FROM ava_members");
$email = mysql_query("SELECT email FROM ava_members");
$dt = mysql_query("SELECT dt FROM ava_members");
//$result = mysql_query("SELECT id,email,dt,regIP FROM ava_members ORDER BY dt LIMIT 5");
$final = "";
$final .= "<table border='1'><tr>";
/* TABELA */
$final .= "<td>Nick</td>";
$final .= "<td>ID</td>";
$final .= "<td>Email</td>";
$final .= "<td>Data</td>";
//$final .= "</tr>\n";
/* TABELA */
//user
while($row = mysql_fetch_row($user))
{
$final .= "<tr>";
foreach($row as $cell)
$final .= "<td>$cell <a href=\"\?usrdel=$cell\"\>[DELETE]</a></td>";
$final .= "</tr>\n";
}
//ID
while($row = mysql_fetch_row($id))
{
$final .= "<tr>";
foreach($row as $cell)
$final .= "<td>$cell</td>";
$final .= "</tr>\n";
}
//email
while($row = mysql_fetch_row($email))
{
$final .= "<tr>";
foreach($row as $cell)
$final .= "<td>$cell</td>";
$final .= "</tr>\n";
}
//dt
while($row = mysql_fetch_row($dt))
{
$final .= "<tr>";
foreach($row as $cell)
$final .= "<td>$cell</td>";
$final .= "</tr>\n";
}
mysql_free_result($user);
mysql_free_result($id);
mysql_free_result($email);
mysql_free_result($dt);
echo '<center>' . $final . '</center>';
And there's output:
But as you can guess that's not what I want...
Output that I want should look like this:
It's pretty simple - just learn in2 html tables

Answer 1

You should learn SQL:
$data = mysql_query("SELECT usr, id, email, dt FROM ava_members");
while ($row = mysql_fetch_row($data))
{
$final .= "<tr>";
foreach($row AS $k => $cell) {
$final .= '<td>' . htmlspecialchars($cell);
if ($k == 'usr') {
$final .= '<td>[DELETE]';
}
$final .= '</td>';
}
$final .= "</tr>\n";
}
And yes, do not use mysql_. Use mysqli_ instead.

Answer 2

Here's a function that I wrote to display the data from a MySQL database as an HTML table:
/* Returns all of the results from a query in one nice table */
/* Example usage: echo $db->allResults("taxi0", "time, latitude, longitude",40,50); */
function allResults($table,$cols,$limstart,$lim) {
if(isset($cols)) {
$query = "SELECT $cols FROM $table LIMIT $limstart,$lim";
}
else {
$query = "SELECT * FROM $table LIMIT $limstart,$lim";
}
$result = $this->query($query);
$output = '<table class="allResults">';
$data = array();
while($row = $this->fetchAssoc($result)) {
$data[] = $row;
}
$colNames = array_keys(reset($data));
$output .= "<tr>";
foreach($colNames as $colName) {
$output .= "<th>$colName</th>";
}
$output .= "</tr>";
foreach($data as $row) {
$output .= "<tr>";
foreach($colNames as $colName) {
$output .= "<td>".$row[$colName]."</td>";
}
$output .= "</tr>";
}
$output .= '</table>';
return $output;
}
Hope it will help you out.

PDO example, as it is both not deprecated and more fun:
// precondition: $row should be a numbered array of column data
function table_row_from_db_row($row) {
$result = '';
foreach($row as $key => $value) {
$result .= "<td>$value</td>\n";
}
return "<tr>\n$result</tr>\n";
}
// precondition: $headers should be an associative array representing the
// first row
function table_head_from_first_row($row) {
$result = '';
foreach($row as $name => $unused) {
$result .= "<th>$name</th>\n";
}
return "<tr>\n$result</tr>\n";
}
// precondition: $sth is a PDO statement handle from a query that returns
// more than 0 rows.
// postcondition: if there were no rows, returns NULL. Otherwise returns
// an HTML table as a string.
function table_from_query_handle($sth) {
$result = '';
// Fetch the first row so we can get column header names.
$row = $sth->fetch(PDO::FETCH_ASSOC);
if(!$row) {
return NULL;
}
$result .= table_head_from_first_row($row);
do {
$result .= table_row_from_db_row($row);
}
while($row = $sth->fetch(PDO::FETCH_ASSOC));
return "<table>\n$result</table>\n";
}
// Alias the column names to the table headers we want to use on the page.
// If we wanted to build the table manually it would still help that we don't
// have two different names for each field (e.g. `dt` and `data`).
$query = "select usr Nick, id ID, email Email, dt Data from ava_members";
// Connect to the database. This belongs in another file in production code.
$dbh = new PDO('mysql:host=localhost;dbname=test');
// Execute the query and get a statement handle.
$sth = $dbh->query($query);
echo table_from_query_handle($sth);
