如何将php变量传递给javascript?

I am using following code to pass PHP variables to javascript. but it is not working.

 function gto(str) {
   document.getElementById('goto').action = str;
   document.getElementById('ID').value = <?php echo "$userid" ?>;
   document.getElementById('name').value = <?php echo "$user_name" ?>;
   document.getElementById('gname').value = <?php echo "$usergname" ?>;
   document.getElementById('fmname').value = <?php echo "$userfname" ?>;
   document.getElementById('img').value = <?php echo "$userimg" ?>;
   document.getElementById('email').value = <?php echo "$useremail" ?>;
   document.getElementById('goto').submit();
  }

Following is the PHP code

<?php
    if($_POST["name"] == null)
    {
        $user_name = 'Annomyous';   
    }
    else{
        $user_name = $_POST["name"];
        $userid=  $_POST["id"];
        $usergname=  $_POST["gname"];
        $userfname=  $_POST["fname"];
        $userimg=  $_POST["img"];
        $useremail=  $_POST["email"];
    }
    echo "<p style='color : white'>$user_name";
    echo "$userid" ;
    echo "$gname";
    echo "$fname";
    echo "$img";
    echo "$email";
    echo "$user_name";
    echo "$user_name</p>";
    $user_name =htmlspecialchars($user_name);
    $user_name =str_replace("<script>","", $user_name);
    ?>


the output is a follows:
ReAlItY TuTs104598758504708047866ReAlItY TuTsReAlItY TuTs//this is php echo output.

JAVASCRIPT OUTPUT:-

 function gto(str) {
       document .getElementById('goto').action = str;
       document.getElementById('ID').value = ;
       document.getElementById('name').value = Annomyous;
       document.getElementById('gname').value = ;
       document.getElementById('fmname').value = ;
       document.getElementById('img').value = ;
       document.getElementById('email').value = ;
       document.getElementById('goto').submit();
   }

Function gto is called here:

<button class="w3-btn header-btn" onclick="gto('Contact.php');">Contact Us</button>

I can see in PHP output I am getting all variable output. but nin juavascript im getting only Annonymous why???? I need to pass post variables to contact us so i am using the form tag and javascript but this is not working Please help me! Thanks in Advance
