Cálculo da curva de Bézier em PHP

Este é um código em PHP que contém funções que implementam o cálculo da curva de Bézier (quadrática e cúbica). Os algoritmos estão escritos em uma estrutura simples e semelhante a aplicação pura das respectivas equações, para deixar o código o mais limpo possível, e assim, didático.

As curvas de Bézier, cúbica e quadrática:
