PHP - 在另一个域上插入进程

Question

I have this condition, there is 2 site with its own database and domain. in this site, there is a form which the data save on database C on another domain.

is there any way to make the "insert process" be on domain C, because after the insert process the data will send via email to a certain address.

I thought to make function on domain C, and call the function in the site(A or B) to run the insert process. but I dont know how to do it. or is there any way to do it.

sorry for bad english

Answer 1

If you are using both site on same server then just make database connection for other database and execute query using this connection for insertion and other connection to access data from current database. and if you are running application on different different server then use Web Service (REST/SOAP) to communicate between application .
