Timeout when using curl_multi functions

[Porl123]

Hi all, I've got a relatively simple script where I'm trying to perform a multiple curl call to several pages as once. I'm running this in wamp and the cURL extension is definitely enabled and normal curl functions work fine. When I run the script below the page times out:

I suspect the timeout's being caused by this section here:

 

$active = null;
do {
$mrc = curl_multi_exec($mh, $active); echo 'g';
} while($mrc == CURLM_CALL_MULTI_PERFORM);

while(false && $active && $mrc == CURLM_OK) {
if(curl_multi_select($mh) != -1) {
do {
$mrc = curl_multi_exec($mh, $active);
} while($mrc == CURLM_CALL_MULTI_PERFORM);
}
}

 

But I can't be sure. This is effectively the sample code given on the php.net page and it's not loading. Can anyone spot the problem?

 

Thanks,

 

Paul

You can try using Rolling Curl to do this.

Ah, thanks. I'll give that a look at.

while($active && $mrc == CURLM_OK) {
if(curl_multi_select($mh) != -1) {
do {
$mrc = curl_multi_exec($mh, $active);
} while($mrc == CURLM_CALL_MULTI_PERFORM);
}
}

 

After some more testing it seems the do..while loop is never reached as curl_multi_select($mh) always returns -1. Also the page times out because the condition in the outer while loop is always true "$active && $mrc == CURLM_OK, " although I'm really not sure why that is. Any thoughts?

Found a solution, not sure if it's the most efficient, but it works.
