用于打印交替加减序列的Php代码

<?php
function printAlternateSequence($n) {
    $num1 = 0;
    $num2 = 1;
    
    for ($i = 1; $i <= $n; $i++) {
        if ($i % 2 != 0) {
            echo $num1 . " ";
            $num1 += 2;
        } else {
            echo $num2 . " ";
            $num2 += 2;
        }
    }
}

$n = 10; // 打印序列的长度
printAlternateSequence($n);
?>
