limit number of characters

[error_22]

Thanks a lot for replying!

Im experiencing a problem though;

If I use...

PHP Code:

echo substr('abcdef', 0, 4);  // abcd 


...It works, but not if I replace "abcdef" with "$adsresult[message]" i just get:

"$ads"

Im assuming it simply prints parts of the variable, what do I ned to change so it actually prints the content of the variable?

Thanks so much
Niklas

EDIT: nvm, it works now, thanks a lot for helping!
