PHP function to build string from numerals?

Question

Hi is there a PHP function to build a string of alpha characters from numerals?

e.g

1 = a
2 = b
3 = c

etc?

each character has an unique ascii code: Take a look at this: asciitable.com I think you need code to convert ascii code to character am i right? — Thomas

You can use the chr() function combined with an offset for this e.g.:

$offset = 96;
echo chr(1 + $offset);
echo chr(2 + $offset);
echo chr(3 + $offset);

Depending on what you want in the end, strtr ^[docs] might be sufficient:

$str = strtr('1234567890', 'abcdefghij', $str);

Iterate the string and use ord() to convert from characters to numeric values. Then apply the necessary offset. If you want to convert from numeral to characters, use chr().

if I understand the question correctly, he wants to change numbers into letters, not the other way around
