6,268 PointsI think the answer here is:
$isIdentical = ($a === "5")
So first you need to check if $a and the string "5" is equal + of the same type (using something like ===). Then you need to assign the answer of that into $isIdentical
Haven't actually watched this video yet, but you could give it a shot ?

10,868 PointsGot stuck here as well! Realizing now that var_dump() is a function that returns the kind and value of whatever is passed into the parentheses (a.k.a. arguments). So, $isIdentical effectively gets declared as a boolean variable once the strict comparison operator is used in Sinead's example. If we take a var_dump on $isIdentical (sorry couldn't resist) then it should return "boolean(false)" to the console since it's purpose is to "dump" information about the variable. In this case we have a variable that is a boolean and it's value is false. More about var_dump here: http://php.net/manual/en/function.var-dump.php

Courses Plus Student 252 Points"Create a new variable name $isIdentical. Compare the variable $a as equal and of the same type as the string "5" and assign the results to $isIdentical."
