PHP Operators Step By Step Tutorial - Part 7: Ternary operator is the other condition of operator which evaluates the expression of representing moderation model of if... else.... statement. Ternary operator is written down with ?:. Its syntax:


(expr1) ? (expr2) : (expr3);

If expr1 is evaluated as true, hence expr2 is done, while if expr2 is evaluated as false, hence expr3 is done.

File name: ternaryoperator.php


<html>
<head>
<title>Using Ternary Operator</title>
</head>

<body>
<h1>Using Ternary operator</h1>
<?
	$x = 15;
	$y = 7;
	$z = ($x > $y)?($x / $y):($y * $x);
	printf ("x = %d <br>", $x);
	printf ("y = %d <br>", $y);
	printf ("z = %d <br>", $z);
	$value = 95;
	$info = ($value>=60)? "Pass": "Do not pass";
	printf ("value = %d <br>",$value);
	printf ("info = %s", $info);
?>
</body>
