how to strip the last $num characters from a string?

[cmason22]

how do i strip the last 3 (for example) characters from a string.

for exaple, how would i turn

"welcome to my phpbuilder thread"

to:

"welcome to my phpbuilder thr"

(can't use str_replace because there might be multiple occurances)

Thanks!
