### PHP语法
|
|||
|
|
|
|||
|
|
PHP语法的结构有点像：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
<?php
|
|||
|
|
|
|||
|
|
// Your PHP code goes here.
|
|||
|
|
|
|||
|
|
?>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
此PHP脚本可以放在文档中的任何位置。 PHP文件通常包含HTML标记和一些脚本代码。 PHP文件的默认文件扩展名为`.php` 。
|
|||
|
|
|
|||
|
|
###如何在PHP中发表评论？
|
|||
|
|
|
|||
|
|
PHP代码中的注释是不作为程序的一部分读取/执行的行。它的唯一目的是让正在查看代码的人阅读。
|
|||
|
|
|
|||
|
|
在PHP中，注释可以通过单行或多行两种方式进行。 下面给出的代码片段解释了它：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
<?
|
|||
|
|
// This is a single-line comment
|
|||
|
|
|
|||
|
|
# This is also a single-line comment
|
|||
|
|
|
|||
|
|
/*
|
|||
|
|
This is a multiple-lines comment block
|
|||
|
|
that spans over multiple
|
|||
|
|
lines
|
|||
|
|
*/
|
|||
|
|
?>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
