<code class="html"><script type="text/javascript">
    var php_var = "<?php echo $php_var; ?>";
</script></code>

Method 2: AJAX Request

Alternatively, you can utilize AJAX to load the PHP variable asynchronously:

<code class="javascript">$.ajax({
    url: 'get_variable.php',
    dataType: 'json',
    success: function(data) {
        var php_var = data.variable;
    }
});</code>
