What is the name of the following type of if/else syntax:
print $foo = ($hour < 12) ? "Good morning!" : "Good afternoon!";
I couldn't find any dedicated page in the php manual. I knew that it existed, because I've read a book (last year) with it, and now I found this post.
This is called a ternary expression
http://php.net/manual/en/language.expressions.php
You should note, this is not an "alternate syntax for if" as it should not be used to control the flow of a program.
In the simple example of setting variables, it can help you avoid lengthy if statements like this: (ref: php docs)
// Example usage for: Ternary Operator
$action = (empty($_POST['action'])) ? 'default' : $_POST['action'];
// The above is identical to this if/else statement
if (empty($_POST['action'])) {
$action = 'default';
} else {
$action = $_POST['action'];
}
However it can be used other places than just simple variable assignent
function say($a, $b) {
echo "{$a} {$b}";
}
$foo = false;
say('hello', $foo ? 'world' : 'planet');
//=> hello planet
