我有一個(gè)數(shù)組，其中有一個(gè)數(shù)組，我想為“power”的每個(gè)數(shù)組值創(chuàng)建一個(gè)新數(shù)組。做這個(gè)的最好方式是什么？原始數(shù)組：Array( [0] => Array ( [date] => 2019-09-16 15:16:03 [stid] => 64 [beam] => 1 [power] => {1,3,7,8,9} [gates] => 5) [1] => Array ( [date] => 2019-09-16 15:17:03 [stid] => 64 [beam] => 1 [power] => {14,15,16} [gates] => 3))編輯：輸出數(shù)組應(yīng)該從 1 開始遞增門Array( [0] => Array ( [date] => 2019-09-16 15:16:03 [gate] => 1 [power] => 1 ) [1] => Array ( [date] => 2019-09-16 15:16:03 [gate] => 2 [power] => 3 ) [2] => Array ( [date] => 2019-09-16 15:16:03 [gate] => 3 [power] => 7 ) [3] => Array ( [date] => 2019-09-16 15:16:03 [gate] => 4 [power] => 8 ) [4] => Array ( [date] => 2019-09-16 15:16:03 [gate] => 5 [power] => 9 ) [5] => Array ( [date] => 2019-09-16 15:17:03 [gate] => 1 [power] => 14 ) [6] => Array ( [date] => 2019-09-16 15:17:03 [gate] => 2 [power] => 15 ) [7] => Array ( [date] => 2019-09-16 15:17:03 [gate] => 3 [power] => 16 ))對(duì)所有 8（5 和 3）個(gè)冪值繼續(xù)，這樣得到的數(shù)組是 8 個(gè)數(shù)組的數(shù)組。

# Original Data Structure
$arr =
[
[
'date' => '2019-09-16 15:16:03',
'stid' => 64,
'beam' => 1,
'power' => '{1,3,7,8,9}',
'gates' => 5
],
[
'date' => '2019-09-16 15:17:03',
'stid' => 64,
'beam' => 1,
'power' => '{14,15,16}',
'gates' => 3
]
];
$output = [];
foreach ($arr as $a)
{
$gateCount = 0;
foreach (explode(',', trim($a['power'], '{}')) as $p)
{
$output[] = [
'date' => $a['date'],
'gate' => $gateCount++ % $a['gates'] + 1,
'power' => $p
];
}
}
print_r($output);
輸出：
Array
(
[0] => Array
(
[date] => 2019-09-16 15:16:03
[gate] => 1
[power] => 1
)
[1] => Array
(
[date] => 2019-09-16 15:16:03
[gate] => 2
[power] => 3
)
[2] => Array
(
[date] => 2019-09-16 15:16:03
[gate] => 3
[power] => 7
)
[3] => Array
(
[date] => 2019-09-16 15:16:03
[gate] => 4
[power] => 8
)
[4] => Array
(
[date] => 2019-09-16 15:16:03
[gate] => 5
[power] => 9
)
[5] => Array
(
[date] => 2019-09-16 15:17:03
[gate] => 1
[power] => 14
)
[6] => Array
(
[date] => 2019-09-16 15:17:03
[gate] => 2
[power] => 15
)
[7] => Array
(
[date] => 2019-09-16 15:17:03
[gate] => 3
[power] => 16
)
)
筆記：
['beam']并且['stid']根據(jù)您的樣本被遺漏了。如果需要，可以輕松添加。

你可以這樣做：
$newArray = [];
foreach ($oldArray as $element) {
foreach ($element['power'] as $power) {
$element['power'] = $power;
$newArray[] = $element;
}
}
