Use string before end 32 characters?

[oni-kun]

I have a hash that is 32 characters long, it's concatenated after another string which is of variable length. How do I extract anything before the end 32 characters? "$string . md5(...);" is what I have to give a clearer picture. I've tried everything with string manipulation and couldn't find a fully working method.. I can't find what just $string is.

Considering the last 32 characters of the string is the hash and you want to remove it use this:

 

$string = substr($string, 0, -32);

 

If you want to remove everything except the hash use this

 

$string = substr($string, -32);

 

Again both is dependent on the 32 digit long hash being on the end of the string as you stated.

Works perfectly, and I learned a thing about strings! Thanks.
