## Drawing A Parabolic Curve With Straight Lines In PHP

A parabolic curve is a type of curve where every point is an equal distance from a focal point. There a number of different way to generate this sort of curve using math, but one of the simplest is to use straight lines to create the illusion of the curve.

The curve is created by diving two axis into equal points and then drawing a line from the first point on one axis to the last point on the opposite axis. Each line of the curve is drawn in the same way, repeating the process of drawing a line between opposite points for every point along the axis.
