Need confirmation of sent information

I used form.send function to deliver form variables to the server.
On the server side I use php script to receive variables and manually add slashes to quotes ’ or ".
However this time I found something wrong.
It turns out that variables sent by the form.send function have already add slashes to quotes ’ or ".
I’m not very sure, so I need conformation of the fact.
Thank you very much!

I’v found where the problem is.
It’s not about dhtmlx.form, but the php .ini file.
When magic_quotes_gpc=On, Magic quotes are added for incoming GET/POST/Cookie data.
