what you intend to do can be done as below method.

<form method="post" >

<input type="text" name="address">
<input type="submit" name="go">

</form>



<?php
    if($_POST){
    if(isset($_POST['go'])){
    call();
    }else{
    echo "Error";
    }
    }
    function call(){
    echo "hi";
    echo $_POST['address'];
    }
?>

You are mixing PHP and JavaScript. If you want a pure PHP solution you could do something like:

<?php
if(isset($_POST['go'])){
     $address = $_POST['address'];
     echo $address;
}
?>

<form method="POST">
  <input type="text" name="address">
  <input type="submit" name="go" method="post">
</form>

With PHP once the form is submitted you can access form values with $_POST so use $_POST['address'] instead of document.address.value
