Are there any best practices for handling file operations in PHP scripts to ensure reliable behavior, especially when dealing with potential changes in PHP versions?

When handling file operations in PHP scripts, it is important to use built-in functions that are consistent across different PHP versions to ensure reliable behavior. One best practice is to always check for errors when performing file operations and handle them appropriately. Additionally, using absolute file paths instead of relative paths can help avoid issues with file paths changing between PHP versions. 

// Example of handling file operations using built-in functions and checking for errors

$file = 'example.txt';
$contents = 'Hello, world!';

// Write to file
if (file_put_contents($file, $contents) !== false) {
    echo 'File written successfully.';
} else {
    echo 'Error writing to file.';
}

// Read from file
if (($fileContents = file_get_contents($file)) !== false) {
    echo 'File contents: ' . $fileContents;
} else {
    echo 'Error reading file.';
}
