Is it possible to write a regex which checks if a string (javascript & php code) is minified?

Is it possible to write a regular expression which checks if a string (some code) is minified? Many PHP/JS obfuscators remove white space chars (among other things). So, the final minified code sometimes looks like this: PHP: $a=array();if(is_array($a)){echo'ok';} JS: a=[];if(typeof(a)=='object'&&(a instanceof Array){alert('ok')} in both cases there are no space chars before and after "{", "}", ";", etc. There also some other patterns which can help. I am not expecting a high accuracy regex, just need one which checks if at least 100 chars of string looks like minified code. Thanks in advice. PURPOSES: web malware scanner
