Comparison operators allow us to "compare" values and return a true/false result. In this video, we'll be taking a look at the less than and greater than operators and combining operators.
Documentation
Ternary Operator
Another conditional operator is the "?:" (or ternary) operator. The expression (expr1) ? (expr2) : (expr3) evaluates to expr2 if expr1 evaluates to TRUE, and expr3 if expr1 evaluates to FALSE.
Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.
Additional Examples
If we were only checking 60 or greater and we are going to do something in either case, we could also use something like:
if ($score < 60) {
echo 'Please try again';
} else {
echo 'You completed the level!';
}
