I am trying to execute this simple script in php:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0); // no headers in the output
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // output to variable
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy_port);
curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP');
curl_setopt($ch, CURLOPT_PROXY, $proxy_ip);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $opts['credentials']);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
I don't know if this is a problem with some tipe of TimeOut or it needs another paramter but sometimes brings the page and others not, why this happens?
