Make every first character uppercase in array

Question

I'm trying to get all my first characters in a PHP array to be uppercase.

PHP code:

<?php
$ordlista = file_get_contents('C:/wamp/www/bilder/filmlista.txt');

$ord = explode("\n", $ordlista);

sort($ord,SORT_STRING);

foreach ($ord as $key => $val) {
    echo $val."<br/>";
}
?>

Answer 1

$ord = array_map('ucfirst', $ord);

Answer 2

$ord=array_map(function($word) { return ucfirst($word); }, $ord);

Answer 3

To support UTF-8 multibyte characters, like "Russian" for example, you would need

$ord = array_map(function($str){
    return mb_strtoupper(mb_substr($str, 0, 1)).mb_strtolower(mb_substr($str, 1));
}, $ord);

This uses the mb_ucfirst function from https://stackoverflow.com/a/14161325/175071

Answer 4

Sometimes, the raw data would looks something like this:

$ord = ['apple', 'GUAVA', 'mango', 'BANANA'];

To full-proof this:

$ord = array_map('ucfirst', array_map('strtolower', $ord));

What this does is it converts everything into a lower case first, then capitalize each word.
