PHP to update incident email

Content

Hello,

We develop some PHP code in order to support Business Rule,

Rule is the following:

Customer receives an automated email that send from our company email (not related to Oracle), and on the email subject there is the customer email, example:

"9/21/2017 Form - order id, Tom B [email protected]"

and we would like to copy/replace the customer email from the subject (bold) and put it into the customer/contact email (replace the original system company address email).

 

In PHP code we divide it into 2 parts, first we enter it to custom field (works great) and second part, to enter to the email address (where we are facing the issues).
