Re: preg_replace \\1 yIKES!

Capitalize the first letter of a word: ucwords()[1] Now, if it's just for practice, then you need a little change in you code, since strtoupper('\\2') will give '\\2' (i.e. does nothing) and the letter will remain the same. One way to do it would be $text = 'hello world (any ...world)'; echo preg_replace('/\b(\w)/Xe', 'strtoupper("\\1")', $text); check the manual[2] for more info...

Wow this is hard I can't wait till I get the hang of it. Capitalize the first letter of a word. echo preg_replace('/(^)(.)(.*$)/', strtoupper('\\2') . '\\3', 'yikes!'); // outputs yikes! Nope didn't work. So I want to see if I'm in the right place: echo preg_replace('/(^)(.)(.*$)/', '\\1' . '-' . strtoupper('\\2') . '-' . '\\3', 'yikes!'); //outputs -y-ikes! So yea I've got it surrounded why now strtoupper: Yikes! -- Atentamente / Sincerely, J. Rafael Salazar Magaña
