[appleeaters]Script Doesn't Quit

I am trying out the example scripts and whenever I run it, the script doesn't end at the end of the game. For example it runs ok, and then I get something like:

---------------Move 159---------------
The player moved from (183,216) to (183,216) (command: 5)
The closest robot (183,216) is 0 unit(s) away from the player (183,216)
The closest apple (189,222) is 8.4852813742386 unit(s) away from the player (183,216)
---------------Move 160---------------
The player moved from (183,216) to (183,216) (command: 5)
The closest robot (183,216) is 0 unit(s) away from the player (183,216)
The closest apple (189,222) is 8.4852813742386 unit(s) away from the player (183,216)
---------------Move 161---------------
The player moved from (183,216) to (183,216) (command: 5)
The closest robot (183,216) is 0 unit(s) away from the player (183,216)
The closest apple (189,222) is 8.4852813742386 unit(s) away from the player (183,216)

... and so on.

Am I doing something wrong?

Doh!

Nevermind, it turns out I didn't realize it but my version of PHP was too old... I upgraded and it works great now.
