YUI compressor is very useful and powerful tool for javascript files compression. Many developers compress their static javascript files but what about files with PHP tags?

But lets try to feed it to YUI: # yui test.js function(){var b;Ext.addShortcut("finance");var a}; PHP tags are stripped away by YUI and ...

According to the specification above i wrote a piece of the PHP code that dumps all headers sent by client under any PHP SAPI: foreach ($_SERVER as $key => $value) { if (strpos($key, 'HTTP_') === 0) { $chunks = e...
