NYCPHP Meetup

[Edward Potter]

I guess after debugging a zillion lines of php code (by the way some
great responses here).  A tip?

BREAK IT DOWN!   Start with <?php  ?>  if you have too. Add your code
line by line. YOU WILL ALWAYS be able to fix the bug. In the end, it's
just a chip made of silicon -which is really just sand!

"Silicon is present in the sun and stars and is a principal component
of a class of meteorites known as aerolites."
