How to find and display the maximum value in PHP?

In PHP, you can utilize the built-in max() function to find the maximum value in a set of numbers and display it using an echo statement.

Here is an example code:

$values = [10, 5, 8, 15, 3];
// 使用max()函数查找最大值
$maxValue = max($values);
// 输出最大值
echo "最大值是：".$maxValue;

This code initially defines an array $values containing a set of numerical values. Then, it uses the max() function to find the maximum value in the array and assigns it to the variable $maxValue. Finally, it prints out the maximum value using the echo statement.

Running the above code will produce:

最大值是：15

You can modify the input array $values according to your own needs, as well as the output format and style.
