PHP -- 添加注释

PHP支持3种风格的注释

1.C++风格（//）的注释

这种注释不能出现?>标记，如果开启short_open和asp_tag设置，>和%>同样不能出现在注释中

<span style="color: #000000;">php    </span><span style="color: #0000ff;">echo</span> 'Hello,PHP!';     <span style="color: #008000;">//</span><span style="color: #008000;">我是注释，不被执行    </span>?>

2.C语言风格，不允许嵌套注释

<span style="color: #000000;">php    </span><span style="color: #008000;">/*</span><span style="color: #008000;">    *我是注释，不被执行    </span><span style="color: #008000;">*/</span>    <span style="color: #0000ff;">echo</span> ‘Hello，PHP!<span style="color: #000000;">’;</span>?>

3.Shell风格，同C++的禁令

<span style="color: #000000;">php    </span><span style="color: #0000ff;">echo</span> 'Hello,PHP!';   <span style="color: #008000;">#</span><span style="color: #008000;">我是注释，不被执行</span>?>
