note 39341 added to function.fwrite

I wrote the following code: $input = ""; if(isset( $_POST['text_input'])) $input = $_POST['text_input']; $low_input = strtolower($input); $stringArray = explode(" ",$low_input); $FileToWrite = 'c:\\inetpub\\wwwroot\\movies\\test.txt'; function fileWrite($str_array,$file) { fopen($file,'wb'); fwrite($file, "["); for($i = 0; $i < count($str_array); $i++) { fwrite($file, "$str_array[$i],"); } fwrite($file, "]"); fclose($file); } fileWrite($stringArray,$FileToWrite); The progam creates the file "test.txt" but i have the following errors in the page: Warning: fwrite(): supplied argument is not a valid stream resource in c:\inetpub\wwwroot\movies\b.php on line 14 Warning: fwrite(): supplied argument is not a valid stream resource in c:\inetpub\wwwroot\movies\b.php on line 17 Warning: fwrite(): supplied argument is not a valid stream resource in c:\inetpub\wwwroot\movies\b.php on line 19 Warning: fclose(): supplied argument is not a valid stream resource in c:\inetpub\wwwroot\movies\b.php on line 20 Any idea why? thanks... ---- Manual Page -- http://www.php.net/manual/en/function.fwrite.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39341 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39341&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39341&report=yes Search -- http://master.php.net/manage/user-notes.php
