What are common reasons for "file_put_contents" not working when moving PHP files from a local Xampp server to a web server?

When moving PHP files from a local Xampp server to a web server, common reasons for "file_put_contents" not working include file permissions, file paths, and server configuration differences. To solve this issue, ensure that the destination directory has the correct permissions for writing files, double-check the file paths to ensure they are correct for the web server, and make sure the server configuration allows for file writing operations. 

// Example code snippet to check file permissions and write content to a file
$file = 'example.txt';
$content = 'Hello, world!';

if (is_writable($file)) {
    file_put_contents($file, $content);
    echo 'File written successfully.';
} else {
    echo 'File is not writable. Check file permissions.';
}
