No, but there are multiple ways this can be done.

You could create a string, loop through it's length, then access the $i 
character in the string.

$sAlpha = 'ABCDEF...XYZ';
for($i=0;$i<26;++$i)
{
   $sLetter = $sAlpha{$i};
   // code
}


or maybe loop through an array of the letters

foreach(array('A','B','C',...,'X','Y','Z') as $sLetter)
{
   // code
}

or even use the ASCII values

for($i=65;$i<91;++$i)
{
   $sLetter = chr($i);
   // code
}


I tend to prefer the first method, but, depending on your situation, one 
of the others might work better.
