如何根据PHP的容量进行排序

Question

我有一组这样的单件容量

$array1 = array("1 Go", "1 To", "2 To", "500 Go", "320 Go")

当我整理它时，它会：

1 Go
1 To
2 To
320 Go
500 Go

我想要的是：

1 Go
320 Go
500 Go
1 To
2 To

我尝试使用natsort()函数，它提供与asort()相同的结果：

1 Go
1 To
2 To
320 Go
500 Go

我怎样才能在PHP中做到这一点呢？

Answer 1

$array1 = array("1 Go", "1 To", "2 To", "500 Go", "320 Go");
$go = $to = array();
foreach($array1 as $v){
    if(strpos($v, 'Go') !== false){
        $go[] = $v;
    }elseif(strpos($v, 'To') !== false){
        $to[] = $v;
    }
}
sort($to);
sort($go);
$array1 = array_merge($go,$to);
print_r($array1);

结果：

Array ( [0] => 1 Go [1] => 320 Go [2] => 500 Go [3] => 1 To [4] => 2 To ) 

Answer 2

试试他的：

$array1 = array("1 Go", "1 To", "2 To", "500 Go", "320 Go");
$toArray = array();
$goArray = array();

foreach ($array1 as $item)
{
     if (strpos($item, "Go")) array_push($goArray, $item);
     else array_push($toArray, $item);
}

asort($toArray);
asort($goArray);

array_merge($goArray, $toArray);
