I would like to replace all chars in a string that are not a-z or 0-9

has to be a faster way.
I know there is a solution but my chemo-brain is slowing me down today. Sorry...
$output = preg_replace('#[^a-z0-9]#i', '', $input);
I always forget what the 'special' 'shortcut' tokens are for specifing
alphanumeric chars, etc in regexps so I mostly end up writing it the long way
round (as above).
and as someone else mentioned str_replace (and preg_replace) can take
arrays of strings for the find and replace args which save you doing multiple
calls -
although to what extent this is true is, I believe, dependant on your php
version
(check the docs for the specifics)
Any suggestions?
TIA
