What potential issue can arise when error messages in PHP cause the footer to disappear?

When error messages in PHP cause the footer to disappear, it is likely due to the error messages being displayed before the footer HTML code. To solve this issue, you can use output buffering to capture the output of the page and then display it all at once after the error messages. This way, the footer will not be affected by the error messages. 

<?php
ob_start(); // Start output buffering

// Your PHP code here

// Display error messages
if ($error) {
    echo "Error: Something went wrong!";
}

// Footer HTML code
echo "<footer>Footer content here</footer>";

ob_end_flush(); // Flush the output buffer
?>
