How do I print out raw string which contain tags in PHP?

Question

For example:

$str="<script>alert('hello');</script>";

If I use echo to print it out, it will pop up an alert window in the browser.

How can I print out the raw string <script>alert('hello');</script> in this case?

Answer 1

Depends if you want the words script in. If yes, then

You should use this.

echo htmlspecialchars($str);

See http://php.net/manual/en/function.htmlspecialchars.php

If not just use strip_tags http://php.net/manual/en/function.strip-tags.php

Answer 2

You can use htmlspecialchars

$str = htmlspecialchars( "<script>alert('hello');</script>" )
