How to get paypal payment details?

Question

PHP

I transfer the payment to php.
In the form I specify:

<input name="return" type="hidden" value="succes" />
 <input name="cancel_return" type="hidden" value="fail" />
 <input name="notify_url" type="hidden" value="notifi" />

Question. =)
How can I accept all the payment data to check whether the user has paid or not and write the payment information to the database.
I also specify in the form
<input name="rm" type="hidden" value="0" />
to receive data in get, but again - where to receive them and what parameters does this data have?

Read the hardware docks from paypal, it makes sense to try to program what you don't know
