Question

I am having problems with cURL not being able to connect to a server that returns an xml feed and am not sure if my code is stacking up and causing the problem. Is it possible the final function called in this foreach loop is still running when the next loop iteration comes round.

Is it possible to make sure all functions in the loop complete before the next iteration begins, or does foreach do this by default anyway? I tried setting a return true on process_xml() and running a test in the loop: if($this->process_xml($xml_array))continue;
but it didn’t seem to have an effect and seems like a bad idea anyway.

foreach($arrayOfUrls as $url){

    //retrieve xml from url as string.
    if($url_xml_string = $this->getFeedStringUsing_cURL($url)){
        $xml_object = simplexml_load_string($url_xml_string);
        $xml_array = $this->feedStringToArray($xml_object);
        //process the xml.
        $this->process_xml($xml_array);
    }                                 
}

No, this is not possible. Each statement is executed and finished before the next statement is run.
