在php中显示html代码

This is my code:

<?php 
   $baseurl = '<base_url>';
?>
<font class="font_style"><?php echo $baseurl;?></font>

When iam trying to display the variable $baseurl it takes as as a html tags and nothing will bedisplayed

But i want to display as:

<font class="font_style"><base_url></font>

How can i do this?

<?php echo htmlspecialchars ($baseurl);?>

Check htmlspecialcharsdoc and htmlentitiesdoc.

Use the html entities &lt; and &gt; instead of the special characters < and >.

Same goes for some other characters, most prominently &amp; instead ot &. Here's a reference for you:

<font class="font_style"><?php echo htmlentities($baseurl);?></font>
