Are there any common pitfalls or errors to watch out for when using the "include" command in PHP?

One common pitfall when using the "include" command in PHP is not checking if the file exists before including it. This can lead to errors if the file is not found or if there are issues with the file path. To avoid this, always use the "file_exists" function to check if the file exists before including it.

$file_path = 'path/to/file.php';

if (file_exists($file_path)) {
    include $file_path;
} else {
    echo "File not found";
}
