Question

i am finding a Curl function which can open particular no. of webpage open at a time also there will no output or returndata false will more good . I need to access 5-10 url at a same time .. I heard abt Curl Multi Threading but dont have proper function or class to use it ..

i find some by searching but most of them seems to be loop mean it i not using continuous connection just one after one ! I want something which can connect multiple connection at a time not one by one !

I made one :

function mutload($url){
if(!is_array($url)){
exit;
}

for($i=0;$i<count($url);$i++){
// create both cURL resources
$ch[] = curl_init();
$ch[] = curl_init();

// set URL and other appropriate options
curl_setopt($ch[$i], CURLOPT_URL, $url[$i]);
curl_setopt($ch[$i], CURLOPT_HEADER, 0);
curl_setopt($ch[$i], CURLOPT_RETURNTRANSFER, 0);

}
//create the multiple cURL handle
$mh = curl_multi_init();

for($i=0;$i<count($url);$i++){
//add the two handles
curl_multi_add_handle($mh,$ch[$i]);
}
$active = null;
//execute the handles
do {
$mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

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

//close the handles
for($i=0;$i<count($url);$i++){
curl_multi_remove_handle($mh, $ch[$i]);
}
curl_multi_close($mh);
}

ok ! but i m confused that will it connect all the urls at a time or one by one ! mre over i am geeting the content also i only want to connect or request to the site do not need ay content from there i used RETURNTRASFER,false but didnt work .. please hlep me thanks !

You’re looking for the curl_multi_* family of functions. Have a look at curl_multi_exec.

Set CURLOPT_NOBODY to prevent curl from downloading any cotent.
