I wrote a rather naive snake implementation... it worked by each position being logged in an array... so each time you move a for loop scanned the array for collisions it would take a little longer. The target machine was a 50Mhz Sparcstation LX so... I thought nothing of it when writing it but it became obvious when running the game. After about 100 indexes it would get so slow you could just about walk away and get coffee, perhaps I exaggerate a bit but still! Rather than using an array of previous positions, I probably should have allocated an array the size of the play area and marked them traversed or not.

NOTES
Note
In PHP versions before 5.0.0 you must use ocicolumnname(3) instead. This name still can be used, it was left as alias of
oci_field_name(3) for downwards compatability. This, however, is deprecated and not recommended.
