Replacing < with &lt; and > with &gt;

[Jack Franklin]

Hi all,

When a user adds a comment to the blog, their entry is put into the database using '<' and '>' so when the comment is displayed, it actually displays the code properly, not the code itself. How can I replace < and > with &lt; and &gt;? I know you use str_replace but you can only replace one thing in that right? So what do I do?

use htmlentities()

PHP: Select all

<?php
$str = "A 'quote' is <b>bold</b>";

// Outputs: A 'quote' is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str);
?>
