What are common reasons for the "Failed to load resource: the server responded with a status of 404" error in PHP websites?

The "Failed to load resource: the server responded with a status of 404" error in PHP websites typically occurs when the server cannot find the requested resource, such as a file or image. This can be due to incorrect file paths, missing files, or misconfigured server settings. To solve this issue, ensure that the file paths in your PHP code are correct and that the necessary files exist on the server.

<?php
// Example of correct file path usage in PHP
$image_path = "images/image.jpg";
echo '<img src="' . $image_path . '" alt="Image">';
?>
