alguém aqui pode achar útil. hhb_curl_exec2 funciona praticamente como curl_exec, mas arg3 é uma matriz que será preenchida com os cabeçalhos http retornados (índice numérico) e arg4 é uma matriz que será preenchida com os cookies retornados ($ cookies ["expires"] => " Sex, 06 de maio de 2016 05:58:51 GMT ") e arg5 serão preenchidos com ... informações sobre a solicitação bruta feita por curl.
A desvantagem é que ele requer que CURLOPT_RETURNTRANSFER esteja ativado, caso contrário, ele gera um erro e substitui CURLOPT_STDERR e CURLOPT_VERBOSE, se você já os estiver usando para outra coisa .. (eu poderia corrigir isso mais tarde)
exemplo de como usá-lo:
<?php
header("content-type: text/plain;charset=utf8");
$ch=curl_init();
$headers=array();
$cookies=array();
$debuginfo="";
$body="";
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$body=hhb_curl_exec2($ch,'https://www.youtube.com/',$headers,$cookies,$debuginfo);
var_dump('$cookies:',$cookies,'$headers:',$headers,'$debuginfo:',$debuginfo,'$body:',$body);
e a própria função ..
