ionCube 10.2+ applied advanced obfuscation techniques tailored to the PHP 7.2 bytecode structure. It randomized instruction mappings and encrypted variable names. This made it much harder to reverse-engineer than code from older PHP 5.x versions. The Truth About Online ionCube Decoders

Even if you break the encryption (which would require brute-forcing a 256-bit key – computationally infeasible), the result is low-level Zend opcodes, not original PHP.
