Full Message is not showing in mobile phone using php sms api - php

Question

Well, I just bought a sms api which is created by php. They provide me this 2 lines:
http://fahimit.com/smsapi.php?
user=username&pass=pass&phone=mobile_numer&senderid=sender_name&message=my_message
\well now i'm using a html form to send sms. But after message send it's not showing full sender name and message.
For example if i use "Test Sender" as sender_name and "Test message test message" as my_message then it's only showing First word like: Test as sender_name and Test as my_message. I don't understand why it's not showing full message and sender name
PHP code:
<?php
if(isset($_POST['Submit']) && $_POST['Submit'] == "Send SMS")
{
$write_numer = $_POST['write_number'];
$sender = inputvalid($_POST['sender']);
$type = inputvalid($_POST['type']);
$select_msg = inputvalid($_POST['select_msg']);
$msg = $_POST['txt'];
$length = strlen($msg);
$err = array();
$ip = $_SERVER['REMOTE_ADDR'];
if(isset($write_numer) && isset($sender) && isset($type) && isset($select_msg) && isset($msg))
{
if(empty($write_numer) && empty($sender) && empty($type) && empty($select_msg) && empty($msg))
$err[] = "All field require";
else
{
if(empty($write_numer))
$err[] = "Write your mobile number";
elseif(strlen($write_numer) > 13 || strlen($write_numer) < 13)
$err[] = "Your mobile number format is not correct";
elseif(!is_numeric($write_numer))
$err[] = "Your mobile number format is not correct";
elseif (!preg_match("/^8801(6|5|7|8|9|1)\d{8}/", $write_numer))
$err[] = "Invalid mobile number";
if(empty($sender))
$err[] = "Select sender name";
if(empty($type))
$err[] = "Select your message type";
if(empty($select_msg) && empty($msg))
$err[] = "Select your message";
}
}
//error count
if(!empty($err))
{
echo "<div class='error'>";
foreach($err as $er)
{
echo "<font color=red>$er.</font><br/>";
}
echo "</div>";
echo "<br/>";
}
else
{
$sms = "http://fahimit.com/smsapi.php?user=MYUSERNAME&pass=MYPASS&phone=".$write_numer."&senderid=".$sender."&message=".$msg."";
$sms = file_get_contents($sms);
if($sms)
{
echo "<div class='success'>Successfully sent your message to $write_numer. Thank You.</div>";
$sql = mysql_query("INSERT INTO e_sent_sms VALUES('', '', '', '$write_numer', '$msg', '', '', '$length', '$type', '$sender', '$current_date', '$ip' )");
}
else
{
mysql_error();
}
}
}
?>

<form name="frm" method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']) ?>">

Can you tell me what's wrong in my code ?

Answer 1

You need to urlencode your text before passing it to the URL. Do like this
$sender = urlencode($sender);
$msg = urlencode($msg);
$sms = "http://fahimit.com/smsapi.php?user=MYUSERNAME&pass=MYPASS&phone=".$write_numer."&senderid=".$sender."&message=".$msg."";
Do this for all the variables that you are going to send it to the URL.
