Question

Take two strings:

"o'sulLivAn"
"doUble-baRrel"

Desired result:

"O'Sullivan"
"Double-Barrel"

I thought ucwords(strtolower($str)) might do the trick but it treats the strings as a single word.

I know I can explode, or rather preg_split the string and then capitalize the parts and put it back together again, but I’m wondering if there’s a better way of doing it?

Usually with PHP and this sort of thing there tends to be a function hiding away somewhere that’d be useful but isn’t obvious or well known.

Answer 1

There’s no php function to do this.

Here’s a one-liner with no loop (kinda)

$str1 = "double-barrel";
$str2 = "o'sulLivAn";


function my_ucase( $str, $chars="-'" ) {
    return implode(array_map( 'ucwords', array_map( 'strtolower', preg_split( "~([".$chars."])~", $str, null, PREG_SPLIT_DELIM_CAPTURE ))));
}

echo my_ucase($str1);
echo my_ucase($str2);
