PHP range() from A to ZZ?

Question

Is it possible to get a range with PHP from A to ZZ*?

a b c ... aa ... zx zy zz

For me this didn\'t work:

range(\'A\', \'ZZ\');

Answer 1

You can combine two foreach loops to generate something like that.

// Single letters
foreach(range('A', 'Z') as $letter) {
    echo $letter;
}

// AA-ZZ combinations
foreach(range('A', 'Z') as $letter1) {
    foreach(range('A', 'Z') as $letter2) {
        echo $letter1 . $letter2;
    }
}
