Description

Using the FTP PluginQuestion, when you try to download a big file you'll encounter an error like this:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 59506688 bytes) in /home/myUser/public_html/lib/wiki-plugins/wikiplugin_ftp.php on line 65

In this case, I had tried to download a 56 MB file with a PHP memory_limit set to 128 MB on my hosting.

Solution

Using readfile instead of file_get_contents. Here's the patch:

 		$type = filetype($local);

 		header("Content-Disposition: attachment; filename=\"$data\"");

 		header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
 		header('Pragma: public');
-		echo "$content";
+		readfile($local);
+		unlink($local);
 		die;
 
 	} else {


With this patch, I had succesfully downloaded (as a test) a 162 MB file with PHP memory_limit set to 128 MB.
