函数式编程 Functional Programming 函数在 PHP 中是”第一等公民”,即函数可以被赋值给一个变量,包括用户自定义的或者是内置函数,然后动态调用它。函数可以作为参数传递给其他函数(这一特性被称为高阶函数),也可以作为函数返回值返回。 PHP 支持递归,也就是函数自己调用自己,但多数 PHP 代码使用迭代

Is Python a functional programming language? In Python, Why would one use a decision statement contained inside the branch of another decision statement? How to get a list of values into columns and rows in python? In Python, assume that the variable plist has been defined and ref...
DFD lets illustrate the flow of data, how the input data are transformed to output results across the sequence of functional transformations. DFD consists of four major components: entities, processes, data stores, data flows. When you need to draw a Data Flow Diagram the ConceptDraw DIAGRAM ...
“Shell and Guts” combinations of object-oriented and functional programming There’s been much talk about a strategy of having functional cores, nuggets, or guts embedded within an object-oriented shell. Here’s a picture frommy recent book: ...
