What does & mean in php?

Question

&& is clear in PHP which means AND. But how about just &?

For example, what does $error['type'] & E_FATAL mean?

Please help me since I am stuck. The code is here:

function shut(){

   $error = error_get_last();

   if($error && ($error['type'] & E_FATAL)){
       handler($error['type'], $error['message'], $error['file'], $error['line']);
   }

}

It's the bitwise AND operator. PHP manual.

Also, read this: Reference - What does this symbol mean in PHP?

Also, when directly in front of a variable ( like &$cow) it means that variable is a reference. That's not the case in this example though. – JAL Sep 21 '13 at 09:59
Yes, but passing/assignment by reference is not what the OP meant. – Mark Sep 21 '13 at 10:00

yes, I said that too. I was just adding to the information. – JAL Sep 21 '13 at 10:02
Yeah, but I figured it's best not to overload him/her with information. Baby steps – Mark Sep 21 '13 at 10:03
