How to capitalise first letter in PHP

resetreset · 07-28-2010, 02:04 AM

Hi,
I have a string such as "helLo wOrlD". I'd like to transform this into "Hello World", ie. capitalise the first letter of every word, and transform the rest into small letters, both being compulsory.
How do I do it?

Thanks.

These should help:

http://www.php.net/manual/en/function.strtolower.php
http://www.php.net/manual/en/function.ucfirst.php

Always try looking at the documentation first!

Googling for "php+proper()", I came across this as the first suggestion. It might also be what you need.

as also the link in the text says, ucwords() does exactly that, so his workaround you posted is quite unnecessary

ucword() for the first letter in a string, ucwords for every word's first letter in a string

You know I find it quite funny that search engines only work on certain continents, in certain states and even sometimes as close as a few suburbs away (as has been my experience). Personally I have yet to come across one of these magical places that allows me to frequent all site on the internet except any of the search engines, even to the point where I go to a site with a search engine built in (say www.linuxquestions.org) and for the life of me I can't access it either.

Well ... live and learn I guess.

I was actually looking for a solution with regular expressions. PHP does have regex's, right?

it has, look at preg_match(), preg_replace(), preg_match_all(), but out of curiosity, why use regex for this?

Oh no particular reason, I've just done this sort of thing before in Perl, and there I used regex's, so I was looking to go the same way here....

, but the solutions suggested above will do just fine!

PHP isn't Perl, so things are done a bit differently.

yeah it isn't, nonetheless it includes above mentioned functions (and couple more) to run regex stuff.
preg stands for, iirc, "perl regular" [expressions]
