php replace question

[hyeclass]

hey,
how can i replace
test[backspace]

with tes

so [backspace] gets replace with backspace ....
donno how to explain this

[Bryon]

You would want it like:

test[backspace]
or
wordtoyomomma[backspace]

Would become:

tes
or
wordtoyomomm

?

So the "[backspace]" gets "taken out", along with the last character in the string?
If you explain more clearly I can help you out.
