How to use a for loop in PHP to output the maximum value of an array?

You can use a for loop and an if statement to find the maximum value in an array. Here is an example code:

<?php
$numbers = array(1, 5, 7, 3, 9, 2);
$max = $numbers[0]; // 假设第一个元素为最大值

for ($i = 1; $i < count($numbers); $i++) {
    if ($numbers[$i] > $max) {
        $max = $numbers[$i]; // 更新最大值
    }
}

echo "数组的最大值为: " . $max;
?>

Here we assume the first element in the array is the maximum value, then we use a for loop to iterate through the array. If a larger element is found, we update the maximum value. Finally, we output the maximum value.

The output results in:

数组的最大值为: 9
