<?php
$filename = 'test.txt';
$somecontent = "Add this to the file\n";
// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {
// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}
// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}
echo "Success, wrote ($somecontent) to file ($filename)";
fclose($handle);
} else {
echo "The file $filename is not writable";
}
?>

is the function you may want to use
or use
if you fopen the file and the result of the operation is false then you can't write the file (maybe for permissions, maybe for UID mismatch in safe mode)
file_put_contents (php5 and upper) php calls fopen(), fwrite() and fclose() for you and return false if something id wrong (you should make yourself sure that false is really the boolean value though).

$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';

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';
}
?>
