PHP is awesome

This is how you create a anonymous function in PHP:

$newfunc = create_function('$a,$b', 'return "ln($a) + ln($b) = " . log($a * $b);');

You've misconfigured your spelling checker. The American spelling is, and always has been, fetid, whereas the spelling you used, foetid, is British. You can tell because the British managed not to mangle the Latin the word is derived from.
Since you seem to be quite bad at technology, perhaps you should find a paper dictionary to confirm this for you if you do not believe me.
