Its prototypefollows:int fwrite(resource handle, string string [, int length])If the optional length parameter is provided, fwrite() will stop writing when length characters havebeen written. Otherwise, writing will stop when the end of the string is found. Consider this example:// Data we'd like to write to the subscribers.txt file$subscriberInfo = 'Jason Gilmore|jason@example.com';// Open subscribers.txt for writing$fh = fopen('/home/www/data/subscribers.txt', 'a');// Write the datafwrite($fh, $subscriberInfo);// Close the handlefclose($fh);■ Tip If the optional length parameter is supplied to fwrite(), the magic_quotes_runtime configurationparameter will be disregarded. See Chapters 2 and 9 for more information about this parameter. This only appliesto PHP 5.3 and earlier, as PHP's magic quoting feature has been deprecated with this release.246
