the example below should turn any character exept "\*" (*= any
char) into an "x":
Besides that all mine needed was a extra \
$term = 'char \not xed';
preg_replace('/(?

This is completly different problem. It isn't a matching issue but
a replacement issue.
preg_replace('/\\\.{1}/', '', $term);
You want to remove all \* characters.

Turn that around. What you need to do is remove \* from your string...
$new_str = preg_replace('/\\./','',$old_str);
Regular expressions are for "pattern matching"... not matching everything
BUT a pattern.

example: "this is \ba test"

isn't there a way to do this?

Maybe...
$term = preg_replace('/[^\\]./','x',$term);
which would replace any character that's NOT a \ followed by any other
character with an x...
Not tested, of course. :)

[PHP] (another) regex difficulty
regular expressions
the example below should turn any character exept "\*" (*= any char)
into an "x":
$term = preg_replace('/[^(\\\)+(.){1}]/', 'x', $term);
but i guess because of the [brackets] the "." (period) is treated as
character "." instead as metacharacter (that matches any char).
anyone knows how to work around this?
thanks for your effort
best wishes,
jns
ps: thanks for your help, holmes and kilimajer!
