Download zip PHP

Question

I'm trying to get a zip file (I don't know size and name before) with a request xml that return me a zip file. I want to download it but sometimes download it all (16mb about) sometimees not( 2mb or 4 mb or 1mb) I don't know why.

This is my code:

$ch2=curl_init();

curl_setopt($ch2, CURLOPT_URL, $this->URL);

curl_setopt($ch2, CURLOPT_TIMEOUT, 5040);

curl_setopt($ch2, CURLOPT_HEADER, 0);

curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch2, CURLOPT_POST, 1);

curl_setopt($ch2, CURLOPT_POSTFIELDS,$this->XMLRequest);

curl_setopt($ch2, CURLOPT_SSL_VERIFYHOST, 1);

curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, FALSE); 

curl_setopt($ch2, CURLOPT_SSLVERSION, 3); 

curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true);



$xml = curl_exec($ch2);



curl_close($ch2);

$file2 = fopen('upload/item.zip','w+');

fwrite($file2, $xml);

fclose($file2);

I have also tried:

file_put_contents('upload/item.zip', $xml);

Can someone help me?

Try CURLOPT_FILE to download large file?

set_time_limit(0); //prevent timeout

$ch2=curl_init();
$file2 = fopen('upload/item.zip','w+');
curl_setopt($ch2, CURLOPT_URL, $this->URL);

curl_setopt($ch2, CURLOPT_FILE, $file2); //auto write to file

curl_setopt($ch2, CURLOPT_TIMEOUT, 5040);
curl_setopt($ch2, CURLOPT_POST, 1);
curl_setopt($ch2, CURLOPT_POSTFIELDS,$this->XMLRequest);
# don't use this. please verify your host & peer properly :)
# curl_setopt($ch2, CURLOPT_SSL_VERIFYHOST, 1);
# curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt($ch2, CURLOPT_SSLVERSION, 3); 
curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true);

curl_exec($ch2);

curl_close($ch2);
fclose($file2);

EDIT:

Notes: As pointed out by @bansi, you might need to verify the file, file size, curl_error, etc.
