exec（）PHP函数不起作用

Question

<?php
    error_reporting(0);
    session_start();
    function code($no_of_char)
        {
            $code='';
            $possible_char="0123456789";
            while($no_of_char>0)
                {
                    $code.=substr($possible_char, rand(0, strlen($possible_char)-1), 1);
                    $no_of_char--;
                }
            return $code;
        }

        function sendSms($msg, $to)
        {

        $to=trim($to);
        $m.=urlencode($msg);

   $smsurl="http://bhashsms.com/api/sendmsg.php?user=*****&pass=*****&sender=******&phone=$to&text=$m&priority=ndnd&stype=normal";

    $return = exec($smsurl);
        return $return;
        }

    ?>

print_r($smsurl) is showing absolutely right command which i want but doesn't executing exec($smsurl) im not familiar with exec() function. Thanks in advance.

Answer 1

exec is used for executing an external program but accessing some webpage/api from a web url is not a valid use case for exec. Try this if you want to get data from an Url.
