用php給5位同學隨機生成語文、數學、英語、化學、物理、政治六門課的成績

//隨機得出每個學生每門課的成績

for ($i=1;$i<6;$i++){

$stuData[$i]['yuwen'] = rand(10,100);

$stuData[$i]['shuxue'] = rand(10,100);

$stuData[$i]['yingyu'] = rand(10,100);

$stuData[$i]['huaxue'] = rand(10,100);

$stuData[$i]['wuli'] = rand(10,100);

$stuData[$i]['zhengzhi'] = rand(10,100);

}

$stuCount = array();

//計算總成績

foreach ($stuData as $k=>$v){

$stuCount[$k] = $v['yuwen'] + $v['shuxue'] + $v['yingyu'] + $v['huaxue'] + $v['wuli'] + $v['zhengzhi'];

}

echo '<pre>';print_r($stuCount);//未排序之前的總成績

//從高到低排序

rsort($stuCount);

echo '<pre>';print_r($stuCount);//排序之後的總成績
