Based on the examples from this page, I wanted to convert the below if statement to a ternary expression.
Working code using if statement:
if (!empty($address['street2'])) echo $address['street2'] . '<br />';
I am not sure how this should be written using a ternary operator so that the echo works only if street2 exists in the array and is not an empty string.
The
(condition) ? /* value to return if condition is true */
: /* value to return if condition is false */ ;
syntax is not a "shorthand if" operator (the ? is called the conditional operator) because you cannot execute code in the same manner as if you did:
if (condition) {
/* condition is true, do something like echo */
}
else {
/* condition is false, do something else */
}
In your example, you are executing the echo statement when the $address is not empty. You can't do this the same way with the conditional operator. What you can do however, is echo the result of the conditional operator:
echo empty($address['street2']) ? "Street2 is empty!" : $address['street2'];
and this will display "Street is empty!" if it is empty, otherwise it will display the street2 address.
