Force php to use proxy -

i have tell php use proxt settings allow connection website. how can force php script use proxy?

i scraped http proxy , want use them.

i tried adding config.php

stream_context_set_default(['http'=>['proxy'=>'101.66.253.22:8080 ']]); 

i tried change function this:

$ch = curl_init(site::link_login); curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_encoding, "utf-8"); curl_setopt($ch, curlopt_post, 1); 

to this:

$ch = curl_init(site::link_login); curl_setopt($ch, curlopt_proxy, '101.66.253.22:8080');       curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_encoding, "utf-8"); curl_setopt($ch, curlopt_post, 1); 

but none of wchich works properly. can me?

try make new curl_setopt proxy port.

curl_setopt($ch, curlopt_proxy, "http://proxy.example.com"); //proxy url curl_setopt($ch, curlopt_proxyport, "8080"); // proxy port number  

maybe... first check error message

if(curl_exec($ch) === false) {     echo 'curl error: ' . curl_error($ch); } else {     echo 'operation completed without errors'; }
