Best way to list Alphabetical(A-Z) using PHP

You can either do:

foreach (range('A', 'Z') as $char) {
    echo $char . "\n";
}

Or:

for ($char = 'A'; $char <= 'Z'; $char++) {
    echo $char . "\n";
}

range() supports letters since PHP 4.1, so you can do this:

$azRange = range('A', 'Z');
foreach ($azRange as $letter)
{
  print("$letter\n");
}

You can do it in this way as well: ASCII range used here.

for($i = 65 ; $i<=90; $i++)
{
  echo chr($i);
}
