Question

I need all words to be in proper case, with first letters capitalized and others lower case.

I tried:

array_walk_recursive($my_array,'ucwords');

But I guess the function needs to be user-defined.

So I wrote:

function ucrecursive($value,$key) {
    return ucwords($value);
}

array_walk_recursive(&$my_array,'ucrecursive');

Still doesn’t work. Any ideas?

EDIT: sample data:

Array
(
    [0] => Array
        (
            [count] => 768
            [value] => SATIN NICKEL
        )

    [1] => Array
        (
            [count] => 525
            [value] => POLISHED CHROME
        )

    [2] => Array
        (
            [count] => 180
            [value] => AGED BRONZE
        )

etc…

Should be pretty easy to build it yourself:

function ucWordsRecursive( array &$array ) {
    foreach( $array as &$value ) {
        if( is_array( $value ) ) {
             ucWordsRecursive( $value );
        }
        else if( is_string( $value ) ){
            $value = ucwords( strtolower( $value ) );
        }
    }
}
