$a="变量的值将被带入";
echo
<br>    php中echo     虽然echo "...";可以断行,但若其中如出现",则仍需做转义<br>处理。需写做:<br>    echo "<br>    aaaa\"uiuie\"<br>    ...<br>    ";<br>    而使用echo     书写格式:<br>    echo     xxx;<br>    其中:1、xxx应符合变量名的要求,可以使用中文;<br>          2、必须存在于独立行中;<br>          3、xxx; 必须顶格,否则出错;<br>          4、$a,函数不被执行,有点模板的意思。<br>    phpinfo();<br>help;<br>?>                   <center>                     </center>
            <p style="width:100%;text-align:center;margin:10px 0">
