Proxy support on multi curl

[calebf]

I have an array of proxies and I need one to be chosen randomly and applied to each curl handle. This script runs successfully when proxy support is removed, but as soon as I try to add a proxy it refuses to connect. My proxies are good. I have private proxies that validate by confirming that the IP address of the requester is on a whitelist of IPs I configured. I've also tried working public proxies with no validation, with the same result. The error it returns is that it "cannot connect to google.com:3238". Why it's trying to connect to that port is beyond me, the proxies I use, their port is 3238, but it should be connecting to IP:PORT then Google.com:80. Not sure why it's mixing them up.  Here's my code:

 

function multi($urls,$proxies,$agents,$referer) {

// create the multi curl handle
$mh = curl_multi_init();
$handles = array();
$i = 0;
foreach ($urls as $url) {
	// create a new single curl handle
	$ch = curl_init();

	// setting several options like url, timeout, returntransfer
	// simulate multithreading by calling the wait.php script and sleeping for $rand seconds
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_HEADER, 1);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_PROXY, $proxies[rand(0,count($proxies))]);
	curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
	curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
	curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
	curl_setopt($ch, CURLOPT_REFERER, $referer);
	curl_setopt($ch, CURLOPT_USERAGENT, $agent);

	// add this handle to the multi handle
	curl_multi_add_handle($mh,$ch);

	// put the handles in an array to loop this later on
	$handles[] = $ch;
	$i++;
}

// execute the multi handle
$running=null;
do {
	curl_multi_exec($mh,$running);
	// added a usleep for 0.25 seconds to reduce load
	usleep (250000);
} while ($running > 0);

echo 'Curl error: ' . curl_error($ch)."<br />".print_r(curl_getinfo($ch));

// get the content of the urls (if there is any)
for($i=0;$i<count($handles);$i++) {
	// get the content of the handle
	$output[] = curl_multi_getcontent($handles[$i]);

	// remove the handle from the multi handle
	curl_multi_remove_handle($mh,$handles[$i]);
}
// close the multi curl handle to free system resources
curl_multi_close($mh);

// echo the output to the screen
return $output;
}

 

I only post on forums as a last resort. Typically a few Google searches solves the problem, but I've spent too much time researching this one with no progress. I'm assuming it's simply a parameter that needs to be added to the CURL handles, but I've tried every proxy related config option out there and still no dice.
