Try something like this
<?php
$hosts = array(
'xx.com',
'yy.com'
);
class TimeoutException extends \Exception {
}
class Curl
{
public function connect($sock, $ch, $dattt, $url)
{
curl_setopt($ch, CURLOPT_PROXYTYPE, 7);
curl_setopt($ch, CURLOPT_PROXY, $sock);
curl_setopt($ch, CURLOPT_TIMEOUT, 25);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_POSTFIELDS, $dattt);
// etc
$result = curl_exec($ch);
// 28 is curl timeout
if (curl_errno($ch) === 28) {
throw new TimeoutException;
}
// some other error handling...
return $result;
}
}
$curl = new Curl;
foreach ($hosts as $socks) {
try {
$result = $curl->connect($socks, $curlResouece, $dattt, $url);
break;
} catch (TimeoutException $e) {
continue;
}
}
if (!isset($result)) {
die('Failed all socks');
}
echo $result;
As for an explanation, you're looping through the socks proxies you've specified. If the CURL error is 28, it'll throw a timeout exception which you catch in the try catch block. You can then continue to the next proxy. If is has a result, it'll break from the foreach and return the result straight away. If all of the socks proxies are unavailable, it'll die an error.
