Question

How can I parse the flash vars from a string like this?

<script type="text/javascript">
flashvars.added = "2010-07-18";
flashvars.name  = "testing+purposes";
flashvars.user  = "jhon+doe";
</script>

I am using curl to get the string.

May not be perfect, but should at least get you started:

$matches = array();
preg_match_all('~flashvars\.([a-z]+) .*=.*"(.*)";~i', $script, $matches);

if (!empty($matches[1])) {
    $flashVars = array();
    foreach ($matches[1] as $index => $key) {
        $flashVars[$key] = $matches[2][$index];
    }
}

var_dump($flashVars);

Probably could be more efficient, but again should help you get started.
