In PHP, what are the implications of using is_file() to check if a file exists before including it in a script?

When using is_file() to check if a file exists before including it in a script, it is important to consider that the file may be deleted or moved between the time it is checked and the time it is included. To solve this issue, it is recommended to use a try-catch block when including the file to handle any potential errors that may occur. 

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

if (is_file($file_path)) {
    try {
        include $file_path;
    } catch (Exception $e) {
        echo 'Error including file: ' . $e->getMessage();
    }
} else {
    echo 'File does not exist';
}
