Answer 1

<?php
$list=array(
    array('name'=>'AAA','score'=>67,'dengji'=>0),
    array('name'=>'BBB','score'=>98,'dengji'=>0),
    array('name'=>'CCC','score'=>43,'dengji'=>0),
);
function cmp($a,$b){
    global $list;
    $a=$list[$a]['score'];
    $b=$list[$b]['score'];
    if($a>$b){
        return true;
    }
    return false;
}
uksort($list,'cmp');
$list=array_values($list);
echo '姓名|分数|名次<br>';
foreach($list as $k=>$row){
    echo $row['name'].'|'.$row['score'].'|'.($k+1);
}
