Process Control in PHP

The process Control of PHP includes three kinds of sequential structure, branch structure and cyclic structure. The branching structure includes an if statement and a switch statement. Loop structure includes for loop, while loop, Do-while Loop, in the array part we will also contact the Foreach Loop statement, with a foreach statement of the array elements to traverse, very convenient.

First, sequential structure

That is, an uncontrolled process that executes code in sequence by default.

Second, the branch structure control of PHP

Let the program code have a selective execution, including a single branch, two branches, and multiple branches.
