With Phpobsu the php code is made almost unreadable by all variables, functions, classes and Interfacees are replaced by random gennerierte combinations of numbers and letters. Select a "start file", all variables, functions, classes and Interfacees of the file to be replaced. The trick in all php files which are in the same directory are identical variable substitution . Your your included files work after encryption still the same as before. If certain variables are not encrypted, so they write them separated by commas, in a file called "db.txt". This file must be in the same directory as Phpobsu.exe. Furthermore, all comments and unnecessary line breaks are removed from the source code and the code thus optimized automatically.
