php3.x

We have a large number of people submitting a large
number of docs...I'm having a problem with some docs
coming through with high ascii characters in the text,
apparently the dbm database we're using chokes on some
high ascii chars.  I need to eliminate characters in
the text from 122 to 255.  I can't seem to find a
simple way to do this....I have a routine, it works
but it takes too long, something like;

for ($i=122; $i<256; $i++){
 
$textline=str_replace(chr($i),'',$textline)

}


Anyone know of a better, faster way to filter out
these high ascii charcters
