How to use the ternary operator in PHP?

The ternary operator in PHP is used to succinctly represent conditional statements. Its syntax is as follows:

$variable = (condition) ? value_if_true : value_if_false;

If the condition is true, $variable’s value will be set to value_if_true; if not, $variable’s value will be set to value_if_false.

For example, the following code uses a ternary operator to determine if a variable is greater than 10, and based on the result of the evaluation, it sets the value of another variable.

$number = 15;
$result = ($number > 10) ? '大于10' : '小于等于10';
echo $result; // 输出：大于10
