SMS platform PHP code in one click_PHP tutorial

Recently, I have had more opportunities to get in touch with SMS platforms. Thinking about it, it seems that the SMS platform for customers is made using PHP. I was itching to find some information to learn about it. The code is as follows:

$flag = 0;
//Data to be posted
$argv = array(
'sn'=>'SDK-BBX-010-XXXXX',
'pwd'=>'XXXXXX',
'mobile'=>'134338XXXXX', //Test mobile phone number
               'content'=>'How are you, test text message'
);
//Construct the string to be posted
foreach ($argv as $key=>$value) {
If ($flag!=0) {
$params .= "&";
$flag = 1;
                                                                                                  $params.= $key."="; $params.= urlencode($value);
$flag = 1;
                                                                                                              $length = strlen($params);
//Create socket connection
             $fp = fsockopen("sdk2.entinfo.cn",80,$errno,$errstr,10) or exit($errstr."--->".$errno);
//Construct the header of the post request
            $header = "POST /z_send.aspx HTTP/1.1rn";
            $header .= "Host:sdk2.entinfo.cnrn";
​​​​​ $header .= "Referer:/mobile/sendpost.phprn";
​​​​​ $header .= "Content-Type: application/x-www-form-urlencodedrn";
           $header .= "Content-Length: ".$length."rn";
            $header .= "Connection: Closernrn";
//Add post string
$header .= $params."rn";
//Send post data
            fputs($fp,$header);
           $inheader = 1;
​​​​​while (!feof($fp)) {
                                                                                                                                                                                                                                                              $line = fgets($fp,1024); //Remove the header of the request packet and only display the return data of the page
If ($inheader && ($line == "n" || $line == "rn")) {
$inheader = 0;
                                                                                                                                If ($inheader == 0) {
                                                                                                                                                                                                                                                                                                                                                                                                   if($line==1)
                                                                    echo 'SMS sent successfully, please check the return value'.$line;
           }else
                                                                         Echo 'SMS sending fails, please check the relevant error problem return value by viewing the return value according to the return value'. $ LINE;
                                                                                              fclose($fp);
