PHP Save String Content To File

There are several reasons why we need to save something to a file stored on web server. With me, I usually save web site performance log, error log, debug log and cached content into a file or just want to check if a particular is writable.

Below is my PHP function that writes the contents of string to a file.

Note: please make sure you set write permission for the folder contains that file and the file is writable.

PHP Write File

[php] <?php
function write_file($content, $file_name)
{
$fp = fopen($file_name, ‘w’);
fwrite($fp, $content);
fclose($fp);
}
?>
[/php]

Usage:

[text] <?php
$content = "A content wil be written.";
$file_name = "writable_folder/filename.txt";
write_file($content, $file_name);
?>
[/text]
