PHP intercepts the way to launch SMS content

The code looks like this: $str _tmp  = dadmin_utils::gbkstrsplit ("SMS Content", 700);//content that is too long returns an array of intercepted content  700 refers to the length of the Intercept     $ Total = count ($str _tmp);    $num  = 1;    foreach ($str _tmp as $str)     {    & nbsp if ($total > 1)       {        $STR = $str. "{$num}/{$total}";        $num ++;     }      $sign = Strtoupper (MD5 ($ke Y. $pMobile. $str. $ip));      $url = "SMS Address from=37&sgin=". $sign. " &tel= ". $pMobile." &msg= ". $str;      $ret = file_get_contents ($url);      $result = Json_decode ($ret, True );   }//Send SMS Method function Gbkstrsplit ($string, $len = 1)   {    $length = strlen ($string);//Get length, Kanji Account for three bytes     $RETSTR = ';    $RETARR = array ();    for ($i = 0; $i < $length; $i + +) {      $RETSTR. = Ord ($string [$i]) > 127? $string [$i]. $string [+ + $i]: $string[$i];      $len _tmp = strlen ($retstr);      if ($len _tmp >= $len) {        $RETARR [] = $retstr;        $RETSTR = ';     }   }    IF ($retstr! = ") {      $RETARR [] = $retstr;   }    return $RETARR; } website Beijing constructionhttp://www.wangzhanjianshegs.com/
