note 59566 added to function.is-uploaded-file

Hi Im using php4 on a mac and wehen I test the file upload example html with isuploaded() function,- the file is named isuploaded.php- like this: <?php if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {    echo "File ". $_FILES['userfile']['name'] ." uploaded successfully.\n";    echo "Displaying contents\n";    readfile($_FILES['userfile']['tmp_name']); } else {    echo "Possible file upload attack: ";    echo "filename '". $_FILES['userfile']['tmp_name'] . "'."; } ?> I get an "error on line 3 of isuploaded.php" message!! here's my html <form enctype="multipart/form-data" action="isuploaded.php" method="POST"> <!-- MAX_FILE_SIZE must precede the file input field --> <input type="hidden" name="MAX_FILE_SIZE" value="30000" /> <!-- Name of input element determines name in $_FILES array --> Send this file: <input name="userfile" type="file" /> <input type="submit" value="Send File" /> </form> Im following the examples on this website and it doesnt' work. I've checked my php.ini file and the file upload is set to "On". anyone have any ideas? thanks ---- Manual Page -- http://www.php.net/manual/en/function.is-uploaded-file.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59566 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59566&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59566&report=yes Search -- http://master.php.net/manage/user-notes.php
