# Collide


Challenge [Link](
There is php code, to get the flag.


From the source code, We know that there is two parameters called `shell` and `pwn`. Also it has different values. To get our flag by crashing the execution of both `hash()` calls and you need to send `shell` and `pwn` as an arrays.
