Embedding HTML in PHP: Common Methods and Code Examples

PHP provides multiple ways to embed HTML, and this guide lists several common methods.

Output HTML with echo

<code>&lt;?php
    $int=rand(0,1);
    if($int==1){
        echo "&lt;p&gt;取到的随机数是1&lt;/p&gt;";
    }else{
        echo "&lt;p&gt;取到的随机数不是1&lt;/p&gt;";
    }
?&gt;
</code>

Embed PHP inside HTML

This approach allows inserting PHP code at any point within a large block of HTML.

<code>&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
      &lt;meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /&gt;
      &lt;meta http-equiv=\"Content-Language\" content=\"zh-CN\" /&gt;
      &lt;title&gt;Hello World&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;?php
      echo \"Hello world!这是正文\";
    ?&gt;
&lt;/body&gt;
&lt;/html&gt;
</code>

Use heredoc (<<<) syntax

The heredoc syntax is useful for outputting large blocks of HTML without escaping.

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

Include external HTML file

An external HTML file (e.g., test.html) can be inserted using PHP's include() function.

<code>&lt;?php
    include(\"test.html\");
?&gt;
</code>
