PHP selector problem

[MeChill]

Hello guys, I'm not sure that here is right part to post this question ( if it's not, accept my apologize and move it <3 )
I have a reseller directadmin panel and i've made a user for myself, i need php version 5.3 on my user but the others are 5.6.
i want to change my new user's php version to 5.3 while the others are still 5.6. i sent a ticket to the shop where i bought reseller from and they answered me that my custombuild version is 2 but there's no option in my domain setup to change my php version ( my support told me i have to send another ticket 7 days later, that's why i am asking from you)
Sorry for my English xD hope u help me.

If there's no PHP selector visible in the domain setup that probably means no second PHP version has been installed on the server. You should contact your support and ask them if it's possible to install PHP 5.3 as a second PHP version with custombuild.
