Hi. I have the script below to upload and unzip files on my website. The problem is that i can only get it ti work on small files that about 2 MB in size. When I try to upload a file that is 50 MB, the progress successfully runs to 100%, then the page refreshes, and i am back at the upload page with NO error message and nothing is uploaded.

What am I doing wrong? What needs to be changed?

<?php
if($_FILES["zip_file"]["name"]) {
	$filename = $_FILES["zip_file"]["name"];
	$source = $_FILES["zip_file"]["tmp_name"];
	$type = $_FILES["zip_file"]["type"];

$name = explode(".", $filename);
$accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/x-compressed');
foreach($accepted_types as $mime_type) {
	if($mime_type == $type) {
		$okay = true;
		break;
	} 
}

$continue = strtolower($name[1]) == 'zip' ? true : false;
if(!$continue) {
	$message = "The file you are trying to upload is not a .zip file. Please try again.";
}

$target_path = "/home1/cleaverc/public_html/temporary/".$filename;  
if(move_uploaded_file($source, $target_path)) {
	$zip = new ZipArchive();
	$x = $zip->open($target_path);
	if ($x === true) {
		$zip->extractTo("/home1/cleaverc/public_html/temporary/"); 
		$zip->close();

		unlink($target_path);
	}
	$message = "Your .zip file was uploaded and unpacked.";
} else {	
	$message = "There was a problem with the upload. Please try again.";
}
}
?>

    I figured out a solution! Apparently my website is set up to automatically prevent uploads from over 10 MB from going through. I had to create a php.ini file and set the maximum file size to make this work. I use Host Monster. For anyone with a similar problem, read this article here.
