Looping through letters instead of numbers
Here are a few examples.
for ($i =ord( 'A'); $i <= ord('Z'); $i++){
print($i . ' '); #> outputs 65,66,67,...,90
}
print($i . ' '); #> outputs 65,66,67,...,90
}
for($i=chr('65'), $j=0; $i<=chr('90'), $j<=25; $i++, $j++){
print($i . ' '); #> outputs A,B,C,...,Z
}
print($i . ' '); #> outputs A,B,C,...,Z
}
Below is an explanation of two functions chr() and ord().
chr ( int ascii ) takes the integer ord ( string string ) takes the string
or
for($letters = range('A','Z'), $i=0; isset($letters{$i}); $i++)
echo $letters{$i}." ";
echo $letters{$i}." ";

By the way A=65 and Z=90 and the rest of the letters are in between. You could print A in html as "ampersand #65;".
