Answer 1

$data = "body {background:#fff;}
a {color:#333; text-decoration:none; }";

if (false === file_put_contents('/css/style.css', $data))
   echo 'Please chmod 777 to /css/ folder';

Answer 2

You can use the is_writable function to check whether the file is writable or not.

For example:

<?php
$filename = '/path/to/css/style.css';
if (is_writable($filename)) {
    echo 'The file is writable';
} else {
    echo 'Please chmod 777 to /css/ folder';
}
?>
