I know how to send a calendar invite by php (icalendar) but I want to just add an event to the receiver's calendar by sending an email. So that there is no RSVP buttons (Outlook) or other response needed.

Can anyone help me with this?

There is no difference between a calendar event and an invite: they both use the standard. The appearance of the RSVP buttons depends on the iCalendar RSVP parameter in the ATTENDEE lines.

For example:

ATTENDEE;CUTYPE=INDIVIDUAL;ROLE=REQ-PARTICIPANT;RSVP=FALSE;CN=Jennifer:mailto:jen@test.ex

The important parameter in there is RSVP. It indicates whether the organizer would like to receive an RSVP or not. Its default value is false, so omitting the parameter establishes the same effect: the recipient receives the invite, and does not request a RSVP.

Note: mail software manufacturers may choose to ignore this: nothing can be done about that... :)
