Getting area from string

[plznty]

How could I only get the [value] area out of the string

document.observe("dom:loaded", function() { initView([value], [random]); });

 

Thanks in advance, I've tried with explodes etc, just got a bit crusty from not doing enough PHP lately

$a= 'document.observe("dom:loaded", function() { initView([value], [random]); }); ';
preg_match('/initView\(\[(.*?)\]/', $a,$out);
echo $out[1];
