Answer 1

I think you should use the range function:

$a=range("A","Z");
foreach($a as $char)
    echo $char."\n";

Answer 2

You can either do:

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

Or:

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

Answer 3

If you're looking for a comprehensive set of Excel functionality, then take a look at PHPExcel which provides a lot of methods for manipulating cell addresses and ranges, as well as reading/writing for Excel and various other spreadsheet file formats

Answer 4

This code for display A,B,...,ZY,ZZ.

function print_char($end_no=90, $start_no=65, $prefix_no=0)
{ $vasant='';
    if($prefix_no==0)
    {
        for($set=$start_no; $set<=$end_no; $set++)
        {
            $vasant.=(chr($prefix_no).chr($set)).', ';
        }
    }
    else
    {
        for($set=$start_no; $set<=90; $set++)
        {
            $vasant.=(chr($set)).', ';
        }
        for($pre_loop=65; $pre_loop<=$prefix_no; $pre_loop++)
        {
            for($set=$start_no; $set<=90; $set++)
            {
                if($set>=$end_no && $pre_loop==$prefix_no)
                {
                    $vasant.=(chr($pre_loop).chr($set)).'. ';
                    break;
                }
                else
                {
                    $vasant.=(chr($pre_loop).chr($set)).', ';
                }
            }
        }
    }
    return $vasant;
}


$show=print_char(90,65,90);
echo $show;

Answer 5

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

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