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

You can use the range() function to get all alphabetic characters in an array in PHP. The range() function generates an array of elements within a specified range. To get all alphabetic characters, you can use the range() function with the lowercase and uppercase ASCII values for the start and end of the range:

<?php

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

print_r($alphabet);

foreach ($alphabet as $letter) {
  echo $letter . " ";
}

?>

or

<?php

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

foreach ($alphabet as $letter) {
    echo $letter . " ";
}

?>

The first example will create an array of lowercase alphabets, and the second one will create an array of both uppercase and lowercase alphabets.
