pour s'inspirer pour faire un package webapp php pour mac

function tor_wrapper($url){
$ua = array('Mozilla','Opera','Microsoft Internet Explorer','ia_archiver');
$op = array('Windows','Windows XP','Linux','Windows NT','Windows 2000','OSX');
$agent = $ua[rand(0,3)].'/'.rand(1,8).'.'.rand(0,9).' ('.$op[rand(0,5)].' '.rand(1,7).'.'.rand(0,9).'; en-US;)';

Adresse et port du TOR

$tor = '127.0.0.1:9050';

Mettez un TimeOut

$timeout = '300';

$ack = curl_init();
curl_setopt ($ack, CURLOPT_PROXY, $tor);
curl_setopt ($ack, CURLOPT_URL, $url);
curl_setopt ($ack, CURLOPT_HEADER, 1);
curl_setopt ($ack, CURLOPT_USERAGENT, $agent);
curl_setopt ($ack, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ack, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ack, CURLOPT_TIMEOUT, $timeout);

$syn = curl_exec($ack);

$info = curl_getinfo($ack);

curl_close($ack);

$info['http_code'];

return $syn;

Et voici comment l'appeler dans vos scripts :

$wrapped = tor_wrapper("http://www.korben.info");
echo $wrapped;
