How can PHP developers effectively debug and troubleshoot issues related to file handling in their scripts, especially when dealing with file paths and content retrieval?

Issue: PHP developers can effectively debug and troubleshoot file handling issues by checking file paths, ensuring proper permissions, and verifying content retrieval methods. 

// Check file path
$file_path = '/path/to/file.txt';
if (file_exists($file_path)) {
    // Ensure proper permissions
    if (is_readable($file_path)) {
        // Retrieve file content
        $file_content = file_get_contents($file_path);
        echo $file_content;
    } else {
        echo 'File is not readable.';
    }
} else {
    echo 'File does not exist.';
}
