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] <?phpfunction 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]
