hiho@ll

i have a big problem with this:
$string = "test:test_test";

with a regex (and using e.g. preg_split) i want to split the above string into:
test
test
test

(how this stuff can be found within the array doesn't matter, the stringparts should be correctly)

the above example works with this:
$regex = "/[^A-Za-z0-9=]/";
e.g.
preg_split($regex,$string);

thats what i want and it works
explanation: split a string using a seperator which is NOT one of those characters: A-Za-z0-9=
but it's not complete:
i want this too
split a string using a seperator which is NOT one of those characters: A-Za-z0-9= AND a escaped non A-Za-z0-9 character!!!!

example: test:test\_test
result: test
test_test
if the result is test\_test it's not a problem

BUT i don't get it work

so any help would be great

thx@ll

So to make sure I understand this clearly: you want a string s to be split into tokens using delimiters which are anything but alphanumeric characters, the '=', and escaped non-alphanumeric characters. To simplify:

delimiter = unescaped non-alphanumeric characters

I don't have the ability to test it however this *might* help:

To match any escaped non-alphanumeric would be:
/\\[^A-Za-z0-9=]/

Perhaps the following:
/[^\\][^A-Za-z0-9=]/

This should match any non-alphanumeric character whose preceeding character is NOT a '\'.
