I am using curl_multi_exec() for just 5 url. Now i have this strange issue. When i run my code on xampp , it works perfect. i can see $running value initialized with 5 and then keeps decreasing. . But, when i tried it on other localhost(on arm architecture), $running gets initialized with 0. so my curl_multi_exec() never returns any response.
Here is the code snippet :
do { curl_multi_exec($master,$running); echo "<pre>"; var_dump($running ); echo "</pre>"; } while($running > 0); Here is my entire code:
$nodes = array( 'https://www.example.com', 'https://www.example2.com', 'https://www.example3.com', 'https://www.example4.com', 'https://www.example5.com' ); $node_count = count($nodes); $curl_arr = array(); $master = curl_multi_init(); for($i = 0; $i < $node_count; $i++) { $url =$nodes[$i]; $curl_arr[$i] = curl_init($url); curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true); curl_multi_add_handle($master, $curl_arr[$i]); } do { curl_multi_exec($master,$running); echo "<pre>"; var_dump($running ); echo "</pre>"; } while($running > 0); for($i = 0; $i < $node_count; $i++) { $results = curl_multi_getcontent($curl_arr[$i]); var_dump($results); } I googled a few things and got to know curl ssl might be an issue. So, i installed another localhost(on ARM) with openssl and curl ssl enabled. Now i have two different localhost(both for ARM) with SSL enabled, this snippet works fine on one localhost and doesn't work on the other one.
And somehow i need that "other one" because it has lot more features.
Someone please guide what might be the issue with this $running initialization?
Any help is appreciated :)
Tried this also, but no success
