PHP htmlentities Double Encoding

Question

I'm trying to save the contents of a WYSIWYG input into an Oracle database. Here's what I'm using:

$data = htmlentities($_POST['data'], ENT_QUOTES, "UTF-8");

My expectation is that when I'm going to put John's as the value for the input, it will be saved on the database as John's , but instead it is being saved as John' .

To me it looks like a double HTML entity encoding issue.

Can you help me fix this?

Answer 1

Browsing through the documentation , I noticed that the last parameter is a boolean for double encoding.

$data = htmlentities($_POST['data'], ENT_QUOTES, "UTF-8", false);

did the trick.
