php 自动排课算法代码

以下是一个简单的 PHP 自动排课算法的示例代码：

// 定义课程表数组
$timetable = array(
    "星期一" => array(),
    "星期二" => array(),
    "星期三" => array(),
    "星期四" => array(),
    "星期五" => array(),
);

// 定义课程数组
$courses = array(
    "语文",
    "数学",
    "英语",
    "物理",
    "化学",
    "生物",
    "历史",
    "地理",
    "政治",
);

// 定义每个课程需要上多少次课
$course_counts = array(
    "语文" => 3,
    "数学" => 4,
    "英语" => 3,
    "物理" => 2,
    "化学" => 2,
    "生物" => 2,
    "历史" => 2,
    "地理" => 2,
    "政治" => 2,
);

// 定义每天最多上多少节课
$max_per_day = 4;

// 随机排课
foreach ($courses as $course) {
    $count = $course_counts[$course];
    for ($i = 0; $i < $count; $i++) {
        $day = array_rand($timetable);
        if (count($timetable[$day]) < $max_per_day) {
            $timetable[$day][] = $course;
        } else {
            $i--;
        }
    }
}

// 输出课程表
foreach ($timetable as $day => $courses) {
    echo $day . ":\n";
    foreach ($courses as $course) {
        echo "\t- " . $course . "\n";
    }
}

该算法随机排课，并且遵守每天最多上多少节课的限制。你可以根据自己的需求，修改该算法以实现更复杂的课程排布。
