绘制一条曲线，在PHP中的多个点周围弯曲？

Question

I want to draw a dynamically generated line that bends around n points in php, depending on input. I know I could use image arc and painstakingly get the curves to overlap at the proper angles so that multiple curves give the illusion of a single bendy line. But is there is an easier/cleaner way?

If you wish the client side to render this I recommend using the canvas tag See reference here: http://www.html5canvastutorials.com/tutorials/html5-canvas-bezier-curves/

Or use imagemagick backend if you with the server side to do it

look up Bezier Primitive on page http://www.imagemagick.org/Usage/draw/#bezier
