如何将密钥添加到现有数组（PHP）

我有一个现有的数组（如下所示）

我在这个数组中有一个所需的键设置——第一个值的键是orderid，所以我希望orderid=>1000000154

我该怎么办？我相信我必须再次爆炸数组，但我不确定如何编写它，我的任何尝试都没有让我更接近

---

谢谢

只需循环使用

explode（）

设置键和值即可。使用分解数组中的第一项作为键，第二项作为值，然后取消设置现有项（数值索引数组元素）以进行清理

$input = array(
    "orderid:100000154",
    "shipping_method:channelunitycustomrate_channelunitycustomrate",
    "qty_ordered:1.0000",
    "shipping_firstname:John",
    "shipping_lastname:Doe",
    "shipping_company:",
    "shipping_street1:123 Fake Street",
    "shipping_street2:",
    "shipping_city:LAUREL",
    "shipping_postcode:20723-1042",
    "shipping_region:Maryland",
    "shipping_country:US",
    "vendor_sku:3397001814",
    "vendor_linecode:",
    "
    "
);

foreach($input as $key => $val) {
    if(strstr($val, ":")) {
        $exploded = explode(":", $val);
        $input[$exploded[0]] = $exploded[1];
    }
    unset($input[$key]);
}
echo "<pre>";
var_dump($input);
echo "</pre>";

在数组上循环，在

：

上分解，并将键/值分配给新数组。

$input = array(
    "orderid:100000154",
    "shipping_method:channelunitycustomrate_channelunitycustomrate",
    "qty_ordered:1.0000",
    "shipping_firstname:John",
    "shipping_lastname:Doe",
    "shipping_company:",
    "shipping_street1:123 Fake Street",
    "shipping_street2:",
    "shipping_city:LAUREL",
    "shipping_postcode:20723-1042",
    "shipping_region:Maryland",
    "shipping_country:US",
    "vendor_sku:3397001814",
    "vendor_linecode:",
    "
    "
);

foreach($input as $key => $val) {
    if(strstr($val, ":")) {
        $exploded = explode(":", $val);
        $input[$exploded[0]] = $exploded[1];
    }
    unset($input[$key]);
}
echo "<pre>";
var_dump($input);
echo "</pre>";

array(14) {
    ["orderid"]=>
      string(9) "100000154"
    ["shipping_method"]=>
      string(45) "channelunitycustomrate_channelunitycustomrate"
    ["qty_ordered"]=>
      string(6) "1.0000"
    ["shipping_firstname"]=>
      string(4) "John"
    ["shipping_lastname"]=>
      string(3) "Doe"
    ["shipping_company"]=>
      string(0) ""
    ["shipping_street1"]=>
      string(15) "123 Fake Street"
    ["shipping_street2"]=>
      string(0) ""
    ["shipping_city"]=>
      string(6) "LAUREL"
    ["shipping_postcode"]=>
      string(10) "20723-1042"
    ["shipping_region"]=>
      string(8) "Maryland"
    ["shipping_country"]=>
      string(2) "US"
    ["vendor_sku"]=>
      string(10) "3397001814"
    ["vendor_linecode"]=>
      string(0) ""
}

$result = array();
foreach($yourArray as $row) {
    list($key, $value) = explode(":", $row);
    $result[$key] = $value;
}
