Accessing Javascript In PHP variable

Question

I have a php variable of javascript code which was parsed from another page. Is there a simple way to access the javascript variables individually with php?

PHP:

$cool = "<script type='text/javascript'>
var Title = 'This is the title';
var Text = 'Some text here';

Title.info.showinfo({

    'thumb':'image.jpg',
    'date':'Oct 2',
    'year':'2011'

});
</script>";

What Im trying to accomplish:

$title = "This is the title";
$text = "Some text here";
$thumb = "image.jpg";
$date = "Oct 2";
$year = "2011";

If the other page cooperates with you, get the data from it as JSON and all will be fine. Otherwise I don't envy you. — Jon

Try this: timwhitlock.info/blog/2009/11/14/… a PHP-based JS parser/tokenizer. Should let you extract those fairly easily. — Marc B

If your input follows a solid pattern, use a RegExp: php.net/manual/en/function.preg-match.php — Rob W

try something like this,

<?php
$data = array(
    'key1' => 'value1',
    'key2' => 'value2'
);
$str = "some string";
?>

then output it using JSON data format,

<script type='text/javascript'>
var data = <?php echo json_encode($data);?>;
var str = <?php echo json_encode($str);?>;

alert(data.key1); // value1
alert(str); // some string
</script>

It's not javascript yet. It's just a piece of string. And there's no simple way to get those values from PHP. Some ways are.

Dive into the string(code) and get the values by explode()ing or pattern matching with regex.
Send the code to client first, let the javascript run and send back via AJAX.
If you have control of the javascript code, make the variables accessible by PHP in the first place.
