            //$url = $tUrl;         
            $vars = "&xml=" . $rc4->limpiaVariable(urlencode($xmlSend)); 
            $header[] = "Content-type: application/x-www-form-urlencoded";
            $ch = curl_init();
            $postfields = "info_asj3=1".$vars;

             curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
             curl_setopt($ch, CURLOPT_URL,$Url);

             curl_setopt($ch, CURLOPT_TIMEOUT, 250);
             curl_setopt($ch, CURLOPT_POST, true);
             curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
             curl_setopt($ch, CURLOPT_HTTPHEADER, $header);          

             $data = curl_exec($ch);
                if (curl_errno($ch)) {
                   $data = curl_error($ch);          
                } else {
                   curl_close($ch);
                }

I am working with a new company that is using this to connect to an xml feed. But using this beginning <<<TEXT is messing up all the code below it. I do not get any errors, the code works, but all my php code below is in black and honestly just is not easy to manage. If I take it out the xml feed does not function properly. Can someone tell me why this is working and what is a better way to accomplish this? I have searched everywhere and can find nothing on the topic. PLEASE HELP!

Thank you to anyone in advance for taking the time to answer!

This is Heredoc syntax of string.

Using Heredoc for string has the benefit for multi-line strings and can avoid the quoting issues.

This is a HEREDOC string, if you are running into problems with it, it's likely due to the indentation of the closing sequence:

TEXT; //<-- must be in the 0th column, of the text file.
