What potential issues can arise when using fwrite in PHP?

One potential issue when using fwrite in PHP is that it may not handle writing data to a file properly, leading to incomplete or corrupted files. To solve this, you can check the return value of fwrite to ensure that the data was written successfully. 

$file = fopen('example.txt', 'w');
$data = 'Hello, World!';

if (fwrite($file, $data) === false) {
    echo 'Error writing to file';
} else {
    echo 'Data written successfully';
}

fclose($file);
