尝试返回键“距离”包含最大值的数组,而不是仅返回值。
IE。从:
[0] => Array
(
[pid] => 1
[type] => lj
[distance] => 211849216
[maxspeed] => 277598944
...
)
[1] => Array
(
[pid] => 1
[type] => lj
[distance] => 230286752
[maxspeed] => 289118816
...
)
[2] => Array
(
[pid] => 1
[type] => lj
[distance] => 230840928
[maxspeed] => 298438336
...
)
...
我希望得到[2]
:
(
[pid] => 1
[type] => lj
[distance] => 230840928
[maxspeed] => 298438336
...
)
我已经能够通过以下方式获得最大值:
function max_dist($a) {
return $a["distance"];
}
$jump = max(array_map("max_dist", $jumps)));
但与 JS/下划线的优雅简单不同:
var jump=_.max(jumps,function(o){
return +o.distance;
});
它只返回最大距离值。
我只需要在 PHP 中遗漏一些简单的东西!
