I have an application which sends bulk emails to client. I have used PHP to develop this application. But my requirement is when i select list of email ids, If it has 3k contacts then divide that list in 3 groups. means in first group there will be 1k contacts, in second group 1k contacts and so on.
How to do this? Is their any inbuilt function in php to do this? or any other solution? please help me with this.
