embed HTML code in php, which is a php type file Add html code~

There are many ways to embed HTML in PHP. Here are several common ways:

The first method: Use echo to output HTML code

Because some HTML elements have double quotes, the content output by echo is enclosed in single quotes to avoid errors and save the escaping step. For example, code like this:

<?php
    if(!$_POST){
    echo ‘<form action="" method="post">
    服务器地址：<input type="text" name="host" value="localhost" /><br />
    数据库账号：<input type="text" name="user" value="" /><br />
    数据库密码：<input type="password" name="pwd" value="" /><br />
    指定数据库：<input type="text" name="db" value="test" /><br />
    <input type="submit" value="确定"/>
    </form>‘;
    }
?>

Copy after login

or this with escape symbols:

<?php
     echo "<input type=\"submit\" value=\"确定\"/>" ;
 ?>

Copy after login

Second method: Directly introduce HTML files into PHP

An HTML file (test.html), the main code is:

<body>
    <p>我是一段Html代码</p>
</body>

Copy after login

Use php's include() function to connect the external HTML file to the PHP file

<?php
    include ("test.html");
?>

Copy after login

Output:

##The third method: use (<<<) marker

This is first seen in the template code of PHP168.

<?php
    print <<<EOT
    <div class="slidecont">{$label[deepblue_mainslide]}</div>
    <div class="newcontainter">
        <div class="head">{$label[deepblue_mainh1]}</div>
        <div class="cont" id="Tab1">{$label[deepblue_maint1]}</div>
        <div class="cont" id="Tab2">{$label[deepblue_maint2]}</div>
    </div>
    <a href="$rs[url]" title="$rs[descrip]" target="_blank">$rs[name]</a>
EOT;
?>

Copy after login

The document between "

" and "EOT;" is directly output. A better way to understand it is "a multi-line echo".

The advantage is that it is convenient to output large sections of HTML, no escaping is required, and variables can be quoted.

But there is one more thing to note when using (

) tags: the end of the identifier string EOT; must be on its own line, and no more content is allowed before or after it. , otherwise this php file will be equivalent to waste.

The EOT tag here can be replaced with any tag, such as
