I just realized that I pasted the wrong while function. It is still
the same, only I meant for it to be:
while( $x > $maxx )
Since $maxx will be a number less that $x. It starts reading the data
from the top left corner of the "graph" However, I now get a 500
error. The error_log says: Allowed memory size of 8388608 bytes
exhausted (tried to allocate 10 bytes)
I've never encountered this in my PHP adventures.
