Way to get all alphabetic chars in an array in PHP?

Question

Is there a way to get all alphabetic chars (A-Z) in an array in PHP so I can loop through them and display them?

Answer 1

$alphabet = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z')

Answer 2

<?php 

$array = Array();
for( $i = 65; $i < 91; $i++){
        $array[] = chr($i);
}

foreach( $array as $k => $v){
        echo "$k $v \n";
}

?>

$ php loop.php 
0 A 
1 B 
2 C 
3 D 
4 E 
5 F 
6 G 
7 H
...

Answer 3

$alphas = range('A', 'Z');

Answer 4

$array = range('a', 'z');

Answer 5

To get both upper and lower case merge the two ranges:

$alphas = array_merge(range('A', 'Z'), range('a', 'z'));

Answer 6

Another way:

$c = 'A';
$chars = array($c);
while ($c < 'Z') $chars[] = ++$c;
