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\');

Please check this simple solution incrementing char.

How to list from A to Z in PHP, and then on to AA, AB, AC, etc

Use this recursive function to get the exact range from A to ZZ

function myRange($end_column = '', $first_letters = '') {
    $columns = array();
    $length = strlen($end_column);
    $letters = range('A', 'Z');

    // Iterate over 26 letters.
    foreach ($letters as $letter) {
      // Paste the $first_letters before the next.
      $column = $first_letters . $letter; 
      // Add the column to the final array.
      $columns[] = $column;
      // If it was the end column that was added, return the columns.
      if ($column == $end_column)
          return $columns;
    }

    // Add the column children.
    foreach ($columns as $column) {
      // Don't itterate if the $end_column was already set in a previous itteration.
      // Stop iterating if you've reached the maximum character length.
      if (!in_array($end_column, $columns) && strlen($column) < $length) {
          $new_columns = myRange($end_column, $column);
          // Merge the new columns which were created with the final columns array.
          $columns = array_merge($columns, $new_columns);
      }
    }

    return $columns;
}

call function like.

print_r(myRange('ZZ'));

will give you result

A B C . . . ZX ZY ZZ
