PHP Quotation

Hello everyone. I have a question about putting quote around variable name in php. By adding quote around the varialbe name itself, shouldn't it be a string when you pass it on to the echo. In JavaScript, when you add string on the variable name, it becomes a string. For exampe

var Name = "Abraham" // global variable
function PrintName() {
    if( Name ==="Abraham") {
       alert("Howdy !" + Name); // alert("Howdy !" +" Name") // "Name" is now string"
}   else {
         alert ("Who are you?");
   }
} 
  PrintName();

Now the PHP part. 

 <?php 
    $name = "Abraham";
     function PrintName() {
        global $name;

        if ($name==="Abraham") {
            # code...
            echo "Welcome ".''."$name"; // "$name" why is this working instead of an error? 
        }
          else{
             echo "Who are you?";
          }
     }
       PrintName();
   ?>

If you use double quotes around a variable in PHP it will not treat the variable as a string. Single quotes, will treat the variable as a string.

<?php

$name = "Colin";
echo "My name is $name"; // will print My name is Colin
echo 'My name is $name'; // will print My name is $name

?>
