Coiling is among the most ancient forms of pottery making. The potter forms coils by rolling clay and then builds up forms by stacking the coils on top of each other and attaching them with liquid clay or slip. The coils are then usually smoothed over, making a smooth surface. Native American pottery is usually made this way and then the pots are covered with colored slip and decorated.
For one thing, it helps give it added stability, as each coil is threaded onto the coil below it. Also, using the coiling technique, it is possible to build thicker or taller walled vessels, which may not have been possible using earlier methods. The technique permits control of the walls as they are built up and allows building on top of the walls to make the vessel look bigger and bulge outward or narrow inward with less danger of collapsing or cracking during firing.

Coil construction can be used for large pots that would be impractical to throw from a single lump. Coils can also be used to throw pots without a driven wheel, or to form irregular shapes that do not lend themselves to throwing on a wheel. A potter uses coils or rolled slabs to help achieve a consistent wall thickness, which tends to make the piece more durable both in firing and everyday use.
No, you are better using the correct type ie: $_POST or $_GET
