问题是如何重置密钥,例如数组:
Array (
[1_Name] => Array (
[1] => leo
[4] => NULL
)
[1_Phone] => Array (
[1] => 12345
[4] => 434324
)
)
重置为:
Array (
[1_Name] => Array (
[0] => leo
[1] => NULL
)
[1_Phone] => Array (
[0] => 12345
[1] => 434324
)
)
Array (
[id] => 3
[user_id] => 1
[clan_id] => 1
[date] => 2009-09-24 09:02:05
[skill1rank] => 1
[skill1lvl] => 2376
[skill1xp] => 1804229942
[skill2rank] => 53
[skill2lvl] => 99
[skill2xp] => 120510105
[skill3rank] => 5526
[skill3lvl] => 99
[skill3xp] => 21581237
[skill4rank] => 622
...
[skill21xp] => 38458116
[skill22rank] => 184
[skill22lvl] => 99
[skill22xp] => 22217059
[skill23rank] => 5267
[skill23lvl] => 99
[skill23xp] => 13396733
[skill24rank] => 101
[skill24lvl] => 99
[skill24xp] => 15724235
[skill25rank] => 903
[skill25lvl] …我如何df -h --total在centos上运行后从下面提取的内容中填充一个包含总价值的变量。注意：结果不是来自命令行，而是来自php文件。
我如何仅使用PHP捕获最后一行中的百分比值？

我的第二个阵列B是: ["1604","1606","1607","1610"]
但是当我执行时:
$results= array_diff($b,$a);
然后我得到了这样的结果但我不想要关联(即2如下).我只想要钥匙.(即1607).
我的输出数组结果是:{"2":"1607"}
我希望输出像["1607"].
采取以下数组：
$fruits = [
'apple', 'banana', 'grapefruit', 'orange', 'melon'
];
葡萄柚令人恶心，所以我想取消它。
$key = array_search('grapefruit', $fruit);
unset($fruit[$key]);
葡萄柚不在我的$fruit数组中，但是我的键不再正确编号。
array(4) {
[0] => 'apple'
[1] => 'banana'
[3] => 'orange'
[4] => 'melon'
}
我可以遍历该数组并创建一个新数组，但我想知道是否有更简单的方法来重置密钥。
