Error in creating contact form with php -

i created simple contact form follows.

    <form method="post" action="mail_receive.php">  <label>name&nbsp;&nbsp;*</label> <input name="name" placeholder="type here">  <label>email&nbsp;&nbsp;*</label> <input name="email" type="email" placeholder="type here">  <label>phone no&nbsp;&nbsp;*</label> <input name="phone" placeholder="type here">  <input id="submit" name="submit" type="submit" value=""> 

and php file called mail_receive.php

<?php $name = $_post['name']; $email = $_post['email']; $phone = $_post['phone']; $from = 'from: someone';  $to = 'admin@gmail.com'; $subject = 'ticket ordering'; $body = "from: $name\n e-mail: $email\n phone:\n $phone";  if (isset($_post['submit'])) {     if ($name != '' && $email != '' && $phone != '') {         if (mail ($to, $subject, $body, $from)) {              echo '<p>your message has been sent!</p>';         } else {              echo '<p>something went wrong, go , try again!</p>';          }      } else {         echo '<p>please fill required fields !!</p>';       } }?>  } 

and uploaded hosting. although can fill form , submit, can't receive email inbox. there wrong?

with mail, it's meant

mail($to, $subject, $message, $headers); 

try this:

$to = "youremailaddress@whatever.com";  $subject = "your tickets yo";  $headers = "from: someone@someone.com\r\n"; $headers .= "reply-to: someone@someone.com\r\n"; $headers .= "mime=version:1.0\r\n"; $headers .= "content-type: text/plain; charset=utf-8\r\n;"  $message = "nice tickets bro.";  mail($to, $subject, $message, $headers); 

and please hope it's example purposes, please don't sending admin@gmail.com because (unless admin@gmail.com, wont recieve e-mail.
