$var++ character increment ?

Anon

This was easy in c....

In PHP,
$var++ doesn`t do "a" -> "b",

something like

$var = (string)(((int)$var) + 1)

doesn`t work either...

any ideas ?

dont know how this works in php (did you
take a look at string-functions?) but i
understand y this works in c.
char is simply a datatype that contains
numbers from 0 to 255. every number specifies
exactly one character. if you do char++ you
increment the number. as a matter of fact
you'll get the next char (if you increment
the char 'Z' you'll get some symbols)

replying to my own post I know but....

I managed to get the result I wanted by:

chr(ord ($var) +1);

Who says PHP doesn't have a little bit of something for every taste?

discobean

chr(ord ($var) +1);

Does anybody know how to do the above in ASP?

I'm using a char(2) character (eg. AA, A😎 as a primary key in my database, and to increment it I'm using a stored procedure in MS SQL.

So I need some code that'll go into the stored procedure to increment it.

I want it in the SP rather than in PHP because it'll have 2 front ends, one in PHP and another in coldFusion.
