What potential issues can arise when using the TOP keyword in a MySQL query in PHP?

When using the TOP keyword in a MySQL query in PHP, one potential issue that can arise is that MySQL does not support the TOP keyword. Instead, you should use the LIMIT keyword to achieve the same functionality. By replacing TOP with LIMIT in your query, you can ensure compatibility with MySQL. 

<?php
// Original query using TOP keyword
$query = "SELECT TOP 5 * FROM table_name";

// Modified query using LIMIT keyword
$query = "SELECT * FROM table_name LIMIT 5";
