+= in php

Hello!

http://www.w3schools.com/php/php_operators.asp According to this, I am supposed to be able to use += instead of $email_body = $email_body . '' but it doesn't work...

1 Answer

Judging by the name of your variable: $email_body, I assume it's a String variable. You cannot do += on Strings because that's used for addition (of integers for example).

What you're looking for is .= which is for concatenating strings.

Got it now, Thanks !
