Pass the email onto another php file

Hi,
I am in progress building a bot. It checks the email status and if inactive it makes it active. I have seperate php file to handle the status change. I capture the user entered email address by $user_email = @$_REQUEST['incoming_message'];. However I am having trouble to pass the same value ($user_email variable) onto the next php file to handle the status check.

I tried to set the attribute with extracted data as value. But it shows the extracted data value as it is. Not the real value.

Kindly help me to sort this out.
