Uppercase first letter and rest lower

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

There is a single, native function that performs title-casing and is multibyte-safe. This is a very tidy solution because you don't need to prepare the string to be all lowercase before making the leading letter of all words uppercase.

Code: (Demo)

$string = "OH HeLlo world, it'S \"NiCE\" 'to' sEe you!";
echo mb_convert_case($string, MB_CASE_TITLE, 'UTF-8');

Output:

Oh Hello World, It's "Nice" 'To' See You!

The above demonstrates that the coment at https://www.php.net/manual/en/function.mb-convert-case.php#119629 is incorrect about the behavior relating to double-quote wrapped words.

Also, in Laravel, there is a helper method that can be mentioned: title().

use Illuminate\Support\Str;

$converted = Str::of('a nice title uses the correct case')->title();

// A Nice Title Uses The Correct Case

If you have multiple words in your string, ucwords() can convert the first letter of each word to uppercase.

$string = 'hello world HELLO, wORlD HOW are You';
echo upperLowerCase($string);

function upperLowerCase($string) {
  return ucwords(strtolower($string));
}

You should go like this

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

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

"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.

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

And voila :)
