How can debugging tools help identify errors in PHP code, such as file handling issues?

Debugging tools can help identify errors in PHP code by providing detailed information about the execution flow, variable values, and potential issues within the code. For file handling issues, debugging tools can help pinpoint where the error occurs, such as incorrect file paths or permissions. By using tools like Xdebug or PHP's built-in debugging functions, developers can step through the code line by line, inspect variables, and track file operations to identify and fix file handling errors. 

// Example PHP code snippet to demonstrate how debugging tools can help identify file handling issues
$file = 'example.txt';

if (file_exists($file)) {
    $content = file_get_contents($file);
    echo $content;
} else {
    echo 'File not found or inaccessible.';
}
