Cut off last char of a string

PHP Code:

---

$str = substr($str,strlen($str)-1); 


---

i thought that would take my string, and take the last char off, how do i do it?

Also, is the newline character "\n" because it isnt working correctly..

In windows the newline consists of two characters \r\n and in MAC OS the newline character is just a carrige return \r. To shaveo ff the last n chracters:

PHP Code:

---

 $str = substr($str, -1); 


---

But if you're just looking to get rid of trailing whitespace, trim() would be a better choice.

Thanks guys, i resolved this myself:

PHP Code:

---

$ip = substr($ip,0,-1); 


---

vAd, that just left me with the last char, it didnt cut it off of the string (well actually i guess it did..)

CornedBee, it isnt the same thing every time, and it is not whitespace ever, thanks though

oops :blush:

Thanks anyways, i should type clearer :wave:
