PHP - echo variable into JavaScript

I am trying to put a value within some javascript code like so:

<?
$page = "test";

echo ('<script id="template-download" type="text/x-jquery-tmpl">
<tr class="template-download{{if error}} ui-state-error{{/if}}">
    {{if erro开发者_如何学运维r}}
        <td class="name" style="display: none;">${name}</td>
        <td class="size" style="display: none;">${sizef}</td>
.....etc...
            {{if thumbnail_url}}
                <img src="Img/');
                $page;
                echo('.jpg">
            {{/if}}
.....etc....
</script>');
?>

And the end value looks like this:

            {{if thumbnail_url}}
                <img src="Img/.jpg">
            {{/if}}

and it doesn't put the value? What am i missing???

You're not echoing page.

echo $page;

thats because you're using single quotes so echo doesnt evaluates $vars and like Joe said, particulary $page is not being echoed
