Question

Character encoding

Good evening.
Can anyone help. There are php files encoded in it, how to understand what is written there? And how also to encode?
\x00\x00\x01\x58
\x00\x00\x00\x20
\x03
\x00\x00\x00\x00
\x90\x76
Can someone help me decode this? And then how to encode back in the same way?
