How to make this work??
Error to compare the two variables together.
<?php $a = 5; $isBoolean = true; $isIdentical = '5'; $isIdentical ($a == $isIdentical); //Place your code below this comment ?>
A few things here:
- On line 5 in your excerpt, you are missing an "=" between $isIdentical and the opening parentheses "(".
- The instructions for the challenge tell you to: "Compare the variable $a as equal and of the same type as the string "5" and assign the results to $isIdentical." So, we aren't just seeing if the values match - we're seeing if the TYPE of value matches (e.g. string, integer, boolean, etc).
So, we should have code that looks like this:
<?php $a = 5; //Place your code below this comment $isBoolean = true; $isIdentical = ($a === "5"); // Note how we use three equals ("===") ?>
Do you see the difference between $a (which has a value of 5) and "5"? There are no quotes around the 5 in $a, because it's an integer. The quotes around "5" tell PHP to handle it like a string. A double equal sign (==) compares the value, a triple equal sign (===) compares the TYPE of value.
Hope that helps - you were on the right track, just missing a couple equal signs :)
