%XX where XX cannot be a certain set of values

[The Letter E]

I'm trying to get a regex to match two places after a %, but when i do a negated character class i can't group two characters together.

 

ie.

$regex = '/%[^20\30\5B]/i';

 

so %1 - %19 would match and %21 - %29 will match and %31 + will match, and anything that isn't 5B will match.

 

I went into it thinking it would be simple, but it's not turning out that way.

 

Thanks for any help.

You have a mixture of different methods applied in your reged. Sounds like you will need negative look ahead and alternation. Give this a try.

 

/%(?!20|30|5B)/i
