我目前有一個包含三個字符串的數組，我的目標是將數組中的這三個字符串轉換為單獨的關聯數組。這是數組：$arr = array( "action: Added; amount: 1; code: RNA1; name: Mens Organic T-shirt; colour: White; size: XL", "action: Subtracted; amount: 7; code: RNC1; name: Kids Basic T-shirt; colour: Denim Blue; size: 3-4y", "action: Added; amount: 20; code: RNV1; name: Gift Voucher; style: Mens; value: ￡20",我想讓關聯數組的鍵是操作、數量、項目代碼等，首先我想我應該嘗試將數組的內容轉換為字符串，以使其更易于管理。// Convert $arr to a string.$imploded = implode(": ",$arr);//echo $imploaded;$str = $imploded;$results = preg_split('/: [;,]/', $str);print_r($results);理想情況下，我希望數組看起來像這樣。我對 PHP 很陌生，所以任何幫助和建議將不勝感激。array( 'action' => '', 'amount' => '', 'code' => '', 'name' => '', 'colour' => '', 'size' => '',);

這可能是您所需要的：
<?php
$arr = array(? ?
? "action: Added; amount: 1; code: RNA1; name: Mens Organic T-shirt; colour: White; size: XL",? ??
? "action: Subtracted; amount: 7; code: RNC1; name: Kids Basic T-shirt; colour: Denim Blue; size: 3-4y",? ??
? "action: Added; amount: 20; code: RNV1; name: Gift Voucher; style: Mens; value: ￡20"
);
? ??
foreach ($arr as $string) {
? ?//Build array
? ?preg_match_all("/ [ ]?([^:]+): ([^;]+)[ ;]? /x", $string, $p);
? ?$array = array_combine($p[1], $p[2]);
? ?//Print it or do something else with it
? ? print_r($array);
}

很簡單：
$arr = array(
"action: Added; amount: 1; code: RNA1; name: Mens Organic T-shirt; colour: White; size: XL",
"action: Subtracted; amount: 7; code: RNC1; name: Kids Basic T-shirt; colour: Denim Blue; size: 3-4y",
"action: Added; amount: 20; code: RNV1; name: Gift Voucher; style: Mens; value: ￡20",
);
$data = [];
foreach ($arr as $line) {
$newItem = [];
foreach (explode(';', $line) as $item) {
$parts = explode(':', $item);
$newItem[trim($parts[0])] = trim($parts[1]);
}
$data[] = $newItem;
}
print_r($data);
在此處撥動。

您可以使用 ：
$tempArray = array();
foreach($arr as $data){
$dataExplode = explode(';', $data);
$temp = array();
foreach($dataExplode as $key => $child){
$childExplode = explode(':', $child);
$temp[$childExplode[0]] = $childExplode[1];
}
array_push($tempArray, $temp);
}
print_r($tempArray); //to print array collection
您將獲得單獨的集合array()

只是為了好玩，還有一種方法可以做到這一點：
$arr = array(
"action: Added; amount: 1; code: RNA1; name: Mens Organic T-shirt; colour: White; size: XL",
"action: Subtracted; amount: 7; code: RNC1; name: Kids Basic T-shirt; colour: Denim Blue; size: 3-4y",
"action: Added; amount: 20; code: RNV1; name: Gift Voucher; style: Mens; value: ￡20",
);
$result = array_map(function($line) {
return array_combine(...array_map(null, ...array_chunk(preg_split('/[:;]\s+/', $line), 2)));
}, $arr);
print_r($result);
基本上，我們用兩個可能的分隔符 : 或 ; 后跟空格來分割該行。
然后 array_chunk 函數將鍵和值分組在一起，我們為每一行得到如下所示的內容：
Array
(
[0] => Array
(
[0] => action
[1] => Added
)
[1] => Array
(
[0] => amount
[1] => 1
)
* * *
通過擴展和映射上面的數組，我們得到它的旋轉版本，如下所示：
Array
(
[0] => Array
(
[0] => action
[1] => amount
* * *
)
[1] => Array
(
[0] => Added
[1] => 1
* * *
)
)
我們現在可以擴展這個數組并將其傳遞給array_combine函數，這樣我們就有了一個很好的關聯數組，其中填充了所需的鍵和值。
然后我們映射所有的線，這樣我們就得到了格式良好的結果。
