What potential issues can arise when using the LIMIT clause in a MySQL query in PHP?

When using the LIMIT clause in a MySQL query in PHP, one potential issue that can arise is that you may not be handling errors properly if the query fails. To solve this issue, you should check for errors after executing the query and handle them accordingly. This can help prevent unexpected behavior in your application. 

<?php
// Establish a connection to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Execute the query with LIMIT clause
$result = $mysqli->query("SELECT * FROM table LIMIT 10");

// Check for errors
if (!$result) {
    die("Error: " . $mysqli->error);
}

// Fetch and process the results
while ($row = $result->fetch_assoc()) {
    // Process the data
}

// Close the connection
$mysqli->close();
?>
