Add header Access-Control-Allow-Origin to XMLHttpResponse in php

Question

I am sending XHR request to server written in php which is working fine. but at some cross domain origin are not allowing loading and processing the response from server. it is throwing error

XMLHttpRequest cannot load http://mydomain/getInfo?blabla. Origin http://www.somedomain.com is not allowed by Access-Control-Allow-Origin.

so how can I set Access-Control-Allow-Origin in the response headers in php?

If your JavaScript runs on example.com and the server you are requesting to is in example.net. Make sure it allows the page your js is running by this header

Access-Control-Allow-Origin: http://example.com/ajax.html

Also you need to send Origin header from ajax to the server

Origin: http://example.com/ajax.html
