PHP file upload

[yonidebest]

I have the following script based on the example script on http://www.w3schools.com/php/php_file_upload.asp . I get the following error now that I my host upgraded the server to PHP 5.5.The error:Strict Standards: Only variables should be passed by reference in /public_html/uploads/upload_file.php on line 7The code:

 $allowedExts = array("jpg", "jpeg", "pjpeg"); $extension = end(explode(".", $_FILES["file"]["name"])); if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/jpg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 3000000) && in_array($extension, $allowedExts))   {   if ($_FILES["file"]["error"] > 0)     {     echo "Return Code: " . $_FILES["file"]["error"] . "<br>";     }   else     {	 $filename = (rand() * rand());		 while (file_exists("images/" . $filename . ".jpg"))		$filename = rand() * rand();	     move_uploaded_file($_FILES["file"]["tmp_name"],     "images/" . $filename . ".jpg");	/* write desc */	$myFile = $filename . ".txt";	$fh = fopen("images/" . $myFile, 'w') or die("can't open file");		fwrite($fh, "age: " . $_POST['age'] . "rn");	fwrite($fh, "religion: " . $_POST['religion'] . "rn");	fwrite($fh, "country: " . $_POST['country'] . "rn");	fwrite($fh, "desc: " . $_POST['desc'] . "rn");	fwrite($fh, "usage: " . $_POST['usage'] . "rn");	fwrite($fh, "time/date: " . date("Y-m-d H:i:s") . "rn");	fclose($fh);     }   } else   {   echo "um, eror";   }

Can anyone tell my why I get this error and how to fix it?

 

Thanks,

Yoni

The function end() expects a variable, not a function call.

$f = explode(".", $_FILES["file"]["name"]);$extension = end($f);
