为什么PHP不能使用Javascript?

A very popular answer in StackOvwerflow suggested that in order to get any php variable within a javascript, simply use php withi angular brackets.

var x= <?php echo "val"; ? >

. However I see that the script given below entirely fails to run If I use this method.
Once I comment out that line script works fine.

<script>
var test=<?php echo "hi"; ?>;
alert(test);
document.title=test;
</script>

Even this simple script is not working.

  1. The page is saved as .php
  2. The page resides in WAMP server and is accessed as localhost/test.php

.
.

EDIT: Full code:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Test</title>

<script>
    var test=<?php echo "hi"; ?>;
    alert(test);
    document.title=test;
</script>

</head>
<body>
<div id="test-canvas" style="float:left;width:100%;height:100%;"></div>
</body>
</html>

    I believe your omitted the ' ' in the script

    <script>var test = '<?php echo $variable; ?>';</script>
    

    Hope this helps, good luck.
