Error on Oct 17, 2016 1:44AM - Invalid argument supplied for foreach() in /home/xxxxx/public_html/root/controllers/post/admin.php on line 391

private function curlMultiRequest($urls, $options = array()) {

        $results = array();
        $mh = curl_multi_init();
        foreach($urls as $key => $val) {        < -------------391 row
            $ch[$key] = curl_init();
            if ($options) {
                curl_setopt_array($ch[$key], $options);

            curl_setopt($ch[$key], CURLOPT_URL, $val);
            curl_setopt($ch[$key], CURLOPT_HEADER, 0);
            curl_setopt($ch[$key], CURLOPT_RETURNTRANSFER, TRUE);
            curl_multi_add_handle($mh, $ch[$key]);
        }

At least show us how you call this function as that is where the mistake is. You are obviously not passing an array as the `$urls` parameter on the function call — RiggsFolly, Oct 17 '16 at 00:50

$urls must be array so you could do this:

...
if(is_array($urls)){
    foreach($urls as $key => $val){
        ...
    }
}else{
    // handle unexpected state
}
...

or

private function curlMultiRequest(array $urls, $options = array()) { ... }

You can write it all to change completely what to do then just replace – Anagashi Oct 17 '16 at 00:08
Actually it would be valid if an empty array was passed. It would just not do anything inside the `foreach()` in that case – RiggsFolly Oct 17 '16 at 00:51

Because $url being passed isn't an array or is empty? Try doing this to see what is being passed to the function:

print_r($url);exit;
