WTF?

PHP Code:

echo rtrim("s/asd", "/asd"); //Outputs nothing
echo rtrim("wws/asd", "/asd"); //Outputs ww 


Why doesn't this work???

If I replace "s" with q it works. However if I replace "s" with "q" and "asd" with "qsd" it doesn't work. Why???

EDIT:

It seems the characters don't have to be in order. How could I fix this?

what exactly are you trying to do?

Are you trying to get it to output:

just s in the first case?

from http://ca3.php.net/rtrim

rtrim — Strip whitespace (or other characters) from the end of a string

I got it solved but was wondering how could I make it so that it only removes characters in order.

i.e.

PHP Code:

rtrim('This is a short short sentence', 'cents');
// returns 'This is a short short ' 


So characters have to be in order.
