Free Letters - Can Punctuation Be Free?

[steco]

I read an archived thread ( I can't post to it so here it is again)
Free Letters - Can Punctuation Be Free?
As suggested, I replaced the following line of code in
includes/functions/function_prices.php

Code: $letters_count = strlen(str_replace(' ', '', $string));
with
Code:
$letters_count = strlen(str_replace(' ', '', str_replace('.', '', $string)));
It does work, for "." but I'd like to add other punctuation as well. Specifically, comma, periods, dashes, and apostrophes. Might someone be able to toss me a clue?
thanks

never mind .. I figured it out. not sure how pretty it is .. but it works.
So, for anyone else struggling with this .....

The pattern is to add a space after the last str_replace('foo', '', then repeat that
str_replace('foo', '',
and don't forget to add another curved bracket after $string

The code previously posted to not charge for the "period" was:

$letters_count = strlen(str_replace(' ', '', str_replace('.', '', $string)));

to allow ' " . , - / ( ) % # I changed it to:

$letters_count = strlen(str_replace(' ', '', str_replace('.', '', str_replace(',', '', str_replace("'", '', str_replace('-', '', str_replace('/', '', str_replace('"', '', str_replace('(', '', str_replace(')', '', str_replace('%', '', str_replace('#', '', $string))))))))))));

BTW single quote was a problem, I eventually solved by putting it in double quotes
If anyone knows a better way to do any of this ... let me know.

I have some code for this that I am playing with that will allow you to say what letters, spaces, characters, etc. are free ...

With luck it will get out in an up coming release ...
