进度条以防止ZIPARCHIVE :: CREATE中的504网关超时

Question

我正在用php创建包含视频之类的大文件的zip文件。 ZIP应该是500mb左右，而当我尝试使用php时，它会因为504 Gateway TimeOut而崩溃。我想添加进度条或其他东西以避免服务器饱和，我认为添加文件时关键在foreach中。

foreach($post['files'] as $file) { 
$zip->addFile($file,basename($file));
}

我已经设置了max_execution_time

ini_set('max_execution_time', 0);

任何想法都是最好的方法吗？

完整代码：

<?php

set_time_limit(0);
ini_set('max_execution_time', 0);


if(isset($_POST['files']))
{ $error = ""; //error holder
{

$post = $_POST; 
$file_folder = "files/"; // folder to load files
if(extension_loaded('zip'))
{ 
// Checking ZIP extension is available
if(isset($post['files']) and count($post['files']) > 0)
{ 
// Checking files are selected

$casting_titulo = $post['casting_titulo'];

$zip = new ZipArchive(); // Load zip library 
$zip_name = $titulo."cast.zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)


{ 

 // Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time";
}

foreach($post['files'] as $file) { 
$zip->addFile($file,basename($file));
}


$zip->close();
if(file_exists($zip_name))
{
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}}
else $error .= "* Please select file to zip "; }
else $error .= "* You dont have ZIP extension"; }
}

?>
