Uppercase first letter and rest lower

问题

Ive been looking around for a way in PHP to have a string converted, so that the first letter becomes uppercase and the rest lower case.

At the moment I am doing what I believe is the standard way:

ucfirst(strtolower($string));

But I have found that some programming languages (ie. tcl) can do it with one cammand:

totitle

Is there a way to do this in PHP? It's not a problem as such, I'm just a curios dude :D

Thanks

回答1:

function totitle($string){
  return ucfirst(strtolower($string));
}

And voila :)

You should go like this

<?php
$string= 'HELLO WORLD';
$string = strtolower($string);
$string = ucfirst($string);
?>

"Title" casing capitalizes each word in a string (i.e. every letter following white space). Your approach would result in "Gone with the wind," whereas title casing would yield "Gone With The Wind".

I wouldn't worry about it: what you're doing is simple and intuitive, and if it gets you what you want, there's not any intrinsic functions that do the same thing.

You can create such function yourself.

Do not forget that you should use mb_* functions for data that was input by user. English is not the only language people use. Look at this question: ucfirst() function for multibyte character encodings
