Comparison between PHP and JS "problem solving" moduls (4) CODE
$empty_Array = []; // returns false, in JS it returns true $test0 = 0; // returns false $test1 = 1; // returns true $string_Zero = '0'; // returns false, in JS it returns true $quotes = ' '; // returns false $null = null; // returns false 
if (0) {                            // false same as empty, true same as 1
	echo "true";
} else {
	echo "false";
}
// therefore condition returns false :)

Operators priority
In first case 'result' will be 'false' because && operator executes first and result will be assign to 'result'. Like this: $result = ("First" && false); 

$result = "First" && false;
var_dump($result);
result will be 'First', because first executes $result = "First" and next execute AND operator. Like this: ($result = "First") && false; 

$result = "First" AND false;
var_dump($result);
