How to prevent PHP from trimming the end of long arguments - php

Question

here is the problem, couldn't find much googling, hope somebody here got the answer for this.
My PHP file is sending emails as feedback to me, and it takes 5 arguments,
whenever I send long arguments to my PHP file, it trims the end of argument 5, which is the longest one, how can I fix that?
To be more clear argument 5 is pretty much the email body.
Here is the PHP code:
<?php
include('Mail.php');
$arg1 = $argv[1]; //appName and version
$arg2 = $argv[2]; //ErrorMessage
$arg3 = $argv[3]; //ErrorData
$arg4 = $argv[4]; //ErrorSource
$arg5 = $argv[5]; //ErrorStackTrace
$arg1 = $_GET['arg1'];
$arg2 = $_GET['arg2'];
$arg3 = $_GET['arg3'];
$arg4 = $_GET['arg4'];
$arg5 = $_GET['arg5'];
$subject = $arg1 ;
$errorMessage = $arg2;
$ErrorData = $arg3;
$ErrorSource = $arg4;
$ErrorStackTrace = $arg5;
$recipients = "myemail";
$from = "errorreport#user.com" ;
$headers = array (
'From' => $from,
'To' => $recipients,
'Subject' => $subject,
);
$body = "ErrorMessage: "."\n".$errorMessage."\n"."ErrorData: "."\n".$ErrorData."\n"."ErrorSource: "."\n".$ErrorSource."\n"."ErrorStackTrace: "."\n".$ErrorStackTrace;
$mail_object =& Mail::factory('smtp',
array(
'host' => 'prwebmail',
'auth' => true,
'username' => 'user',
'password' => 'pass', ));
$mail_object->send($recipients, $headers, $body);
?>

I can see your code is referencing $_GET variables, please change your form to use a method of POST
If you are able to, shy away from GET method forms when sending large data.
find:
<form method="get">
replace with:
<form method="post">
then change:
$arg1 = $_GET['arg1'];
to:
$arg1 = $_POST['arg1'];
etc...
