preg_replace

what do i change so my preg_replace allows spaces too?  At the mo, it allows letters a-z upper and lower and numbers 0-9... but i need to keep spaces...

preg_replace('/[^a-z0-9]/i','',$string);

Add a space into your regexp:

preg_replace('/[^a-z0-9 ]/i','',$string);

-r-

Yes :-)

The block-anchors define a set of characters [a-z] matches all alpha's, [a-z ] al alpha's and spaces.

By using [^ instead of [ you can match all characters but the ones inside the [].

So [^a-z0-9 ] matches all but alphanumerics and spaces.

-r-
