我有一个从DB输出的数组

Array

    (
        [0] => Array
            (
                [name] => Fernando Alonso
                [time1] => 3.25
                [time2] => 3.25
                [time3] => 3.5
            )

        [1] => Array
            (
                [name] => Jenson Button
                [time1] => 34
                [time2] => 41
                [time3] => 41
            )
    )

我想要做的是为每个司机输出他们的名字和最快的时间,比如

费尔南多·阿尔索索,时间3 - 3.5

简森巴顿,时间2,时间3 - 41

我正在使用max()进行游戏但由于第一个元素是字符串而不是int / num,因此遇到麻烦而无法正常工作

任何想法我怎么写这个功能?

好的,你去吧,你试试max()

是对的
function get_highest_time($driver) {
    // First find the highest time
    $highest_time = max($driver['time1'], $driver['time2'], $driver['time3']);
    // now find all of the array keys that match that time
    $times = array_keys($driver, $highest_time);
    // now turn that array of keys into a string and add the highest time to the end
    return implode(', ', $times) . ' - ' . $highest_time;
}

foreach ($arr as $driver) { // Where $arr is your array of drivers
    print $driver['name'] . ': ' . get_highest_time($driver) . '<br />';
}

修改

刚刚注意到你说你想要驾驶员最快的时间,这肯定是最低的数字?如果是max()

,请交换min()
