PHP JAVASCRIPT參數傳遞

Question

我在php頁面中有這樣的代碼

<?php
$a = 1;
<script>
var foo<?php echo $a?> //Var foo1 will be created
</script>
?>

但是然后我想分離javascipt頁面並傳遞一個參數

<?php
 // some scripts here...

<script src="initialize.js"></script>
<script>
$(document).ready(function(){
        initialize(<?php echo $a?>);
    });
</script>

javascript頁面/initialize.js

initialize(a){  var foo+a } // i also wanted to create a var foo1

但是控制台將錯誤無法初始化foo + a變量

我想獲得的是從這里創建一個javascript var foo1

謝謝

<?php
    $a = 1;
    echo "<script> var foo".$a.";</script>"
?>

或在您的HTML內

<?php $a = 1; ?>
<script>
var foo<?php echo $a?>;
</script>
