CURL - sending variables with GET not working - php

Question

I want to send the request to another site with GET request and should return a string value. I am using the following cURL code to achieve this but its getting failed.
$user = 'username';
$password = 'password';
$sender_id = 'myid';
$sender_mobile = mobile number;
$message_text = 'Hi Testing SMS';
$priority = 'ndnd';
$sms_type = 'normal';
$redirect_link = "http://bhashsms.com/api/sendmsg.php?user=$user&pass=$password&sender=$sender_id&phone=$sender_mobile&text=$message_text&priority=$priority&stype=$sms_type";
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$redirect_link);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$output=curl_exec($ch);
if($output == false)
{
echo "Error Number:".curl_errno($ch)."<br>";
echo "Error String:".curl_error($ch);
}
$info = curl_getinfo($ch);
curl_close($ch);
But if i use the header its sending successfully the following is using header
$user = 'username';
$password = 'password';
$sender_id = 'myid';
$sender_mobile = mobile number;
$message_text = 'Hi Testing SMS';
$priority = 'ndnd';
$sms_type = 'normal';
$redirect_link = "http://bhashsms.com/api/sendmsg.php?user=$user&pass=$password&sender=$sender_id&phone=$sender_mobile&text=$message_text&priority=$priority&stype=$sms_type";
header("Location:$redirect_link");
where am I going wrong!!!

Answer 1

You have an error on $sender_mobile = mobile number; should be like this $sender_mobile = 'mobile number';
