I am working on a PHP application that takes queries in a text box and returns paginated results. As part of the application I want to report the running time of the query.
Here is what I have done so far.
I started off by enabling profiling in by directly entering in the text box and running the script:
set global profiling = 1
Using the provided text box I enter the following query:
select @@profiling
And get:
1
Finally, I run the query as so:
select * from log
However, when I run the command for to profile the query:
show profiles
I receive no result and no content displayed on the page.
Since I see no table after the command "show profiles" does this mean that there are not sufficient privileges or am I missing another step?
I followed the procedure on:
Measuring actual MySQL query time
Please advise.
My PHP code is as follows:
<?php
if($_POST)
{
$db = new PDO('mysql:host=localhost;dbname=<dbname>;charset=utf8', 'user', 'pass');
$stmt = $db->prepare($_POST['query']);
$stmt->execute();
$records = $stmt->fetchAll(PDO::FETCH_ASSOC);
$errmsg = $stmt->errorInfo()[2]; //Output the error message - Index 2 of the array
echo $errmsg;
}
?>

<? if (isset($records)): ?>

<tr>
<? foreach($record as $colname => $value): ?>
<td>
<?=$value;?>
</td>
<? endforeach; ?>
</tr>
<? endforeach; ?>
</table>
<? endif; ?>
</body>
</html>
Any help would be appreciated.
