Tips, tricks and tools for creating your own data-driven app, brought to you in partnership with Qlik.

In looking at my Google Analytics statistics, I see a lot of visitors searching for PHP shorthand if/else (ternary) information. I've gone through my code library and picked out some examples of ternary operator usage.

Basic True / False Declaration

$is_admin = ($user['permissions'] == 'admin' ? true : false);

Conditional Welcome Message

echo 'Welcome '.($user['is_logged_in'] ? $user['first_name'] : 'Guest').'!';

Conditional Items Message

echo 'Your cart contains '.$num_items.' item'.($num_items != 1 ? 's' : '').'.';

Conditional Error Reporting Level

error_reporting($WEBSITE_IS_LIVE ? 0 : E_STRICT);

Conditional Basepath

echo '<base href="http".($PAGE_IS_SECURE ? 's' : '').'://mydomain.com" />';

Nested PHP Shorthand

echo 'Your score is:  '.($score > 10 ? ($age > 10 ? 'Average' : 'Exceptional') : ($age > 10 ? 'Horrible' : 'Average') );

Leap Year Check

$is_leap_year = ((($year % 4) == 0) && ((($year % 100) != 0) || (($year %400) == 0)));

Conditional PHP Redirect

header('Location: '.($valid_login ? '/members/index.php' : 'login.php?errors=1')); exit();
