Question

Just curious if anyone knows a quick way to use ucwords() on a string replacining
underscores with spaces? I have a preg_replace that will do it, but won’t add the
needed spaces in between…

// this_string_contents -> ThisStringContents
preg_replace('/(?:^|_)(.?)/e',"strtoupper('$1')",$string); 

And the reverse

// ThisStringContents -> this_string_contents
strtolower(preg_replace('/([^A-Z])([A-Z])/', "$1_$2", $string)); 

It would be nice if these were symmetrical too, the above
will do something like this

* this_is_a_string -> ThisIsAString -> this_is_astring
* GetURLForString -> get_urlfor_string -> GetUrlforString

Don’t use regex if you don’t have to- use str_replace instead.

str_replace('_', ' ', $string);
