如何在php中逐字显示echo内容

Question

I'm looking to literally display the contents of echo or print instead of PHP processing the HTML contained within.

For example, if I have the following: echo("<a href='$file'>$file</a> <br /> "); the PHP parser will literally display all my files within a directory as links. What if I wanted to literally output the HTML tags without executing them so that would be displayed as plain text?

Thanks.

Instead of echo, use php function htmlentities inside a html code tag:

echo "<code>";
echo htmlentities("<a href='$file'>$file</a> <br />
");
echo "</code>";
