[TOC]One, for loopRepeated execution of a series of commands is common in programming. Usually you need to repeat a set of commands until you reach a certain condition, such as working with all the files in a directory, all users on the system, or
We will introduce the first container in SSIs 2008: For Loop container,This container is not used in many practical applications, but it is useful in some special scenarios. It is used to realize the loop of a variable and assign values to the
There are three types of cycles:1. For loopFormat: For (initialization of the loop variable; loop condition; increment of the loop variable) {loop body}2. While loopFormat: while (condition) { loop body }3. Do While loopFormat: Do {

Preface
For the for loop, I believe it is not common. But this is because I didn't understand the meaning of a for loop when I read the code.
This for loop is written as
The loops in Python are basically the same as the loops in other languages, except that the writing format is different.1. for loop: for [loop condition]:[Loop statement] satisfies the loop condition, executes the loop statement, executes one time

There are several methods to jump out of the loop in php, one is to use goto, and the other is to use the new php goto command. I will introduce it below.
Break is used in various loops and switch statements mentioned above. Its role is to jump out
