In PHP with PDO, how to check the final SQL parametrized query?
In PHP with PDO, you can use the debugDumpParams() method on a prepared statement object to view the final SQL parametrized query.
In PHP with PDO, you can use the debugDumpParams() method on a prepared statement object to view debugging information about the prepared statement and its bound parameters. Here is an example:
Example of checking the final SQL parameterized query with PDO in PHP
<?php
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$stmt->bindValue(':id', $user_id);
$stmt->execute();
$stmt->debugDumpParams();
<div class="alert alert-info flex not-prose">
<span class="hidden md:block">Watch a video course</span>Learn object oriented PHP</div>
Note that PDO does not natively construct or print the final SQL query with parameter values substituted. debugDumpParams() only outputs an array of debugging details (such as the SQL string, parameter types, and values) to the console. If you need the fully resolved SQL string, you will need to manually replace the placeholders or use a logging middleware.
