the answer is 'b=2' because first the value of 'a' is assigned to the variable 'b' then it is incremented. since at the time of assignment its value is 2 so result is "b=2"

it is important to understand the order of operations with the increment operator. There are 2 versions of the increment operator: $a++ ++$a there's one important a subtle difference between them. $a++ executes the increment LAST inside the line of code. ++$a executes the increment FIRST inside the line of code. example: $a = 5 print($a++) // prints 5 since increment executes after print. print($a) // prints 6 print (++$a) // prints 7 since increment executes before print.
