Question

以下数组来自$ output变量

Array
(
    [title] => Subtotal
    [data] => $1,104.05
)
Array
(
    [title] => Total Shipping
    [data] => $56.45
)
Array
(
    [title] => Order total
    [data] => $1,160.50
)
Array
(
    [border] => top
    [title] => Paying by
    [data] => PayPal
)

我想将以下数组与上面的数组分开，并希望将其存储在新变量中。注意：阵列变得动态。

Array
(
    [title] => Order total
    [data] => $1,160.50
)

请帮助!!

Answer 1

试试这个，

$array = array(
    Array
(
    [title] => Subtotal
    [data] => $1,104.05
)
Array
(
    [title] => Total Shipping
    [data] => $56.45
)
Array
(
    [title] => Order total
    [data] => $1,160.50
)
Array
(
    [border] => top
    [title] => Paying by
    [data] => PayPal
)
);

$second_array = array();

foreach($array as $key => $arr){
    if(isset($arr['title']) && $arr['title'] === 'Order total'){
        $second_array = $arr;
        unset($array[$key]);
    }
}

此代码将检查title密钥是否设置及其值

Answer 2

$array = [
    [
    'title' => 'Subtotal',
    'data' => '$1,104.05'
    ],
    [
    'title' => 'Total Shipping',
    'data' => '$56.45'
    ],
    [
    'title' => 'Order total',
    'data' => '$1,160.50'
    ],
    [
    'border' => 'top',
    'title' => 'Paying by',
    'data' => 'PayPal'
    ]
];


for($i = 0; $i<=count($array); $i){
    if(isset($array[$i]['title']) && $arr[$i]['title'] === 'Order total'){
        $newarr = $arr;
        unset($array[$key]);
    }
}

Answer 3

您应该使用array_filter()。

$array = [
    [
    'title' => 'Subtotal',
    'data' => '$1,104.05'
    ],
    [
    'title' => 'Total Shipping',
    'data' => '$56.45'
    ],
    [
    'title' => 'Order total',
    'data' => '$1,160.50'
    ],
    [
    'border' => 'top',
    'title' => 'Paying by',
    'data' => 'PayPal'
    ]
];

$array = array_filter($array, function($ar) {
   return ($ar['title'] == 'Order total');  //check condition and return record with key
});

$newArray = [];  // your new array
$key = key($array);  // get key of result array
$newArray = $array[$key];  // assign result record to new array
echo "<pre>"; print_r($newArray);

<强>输出： -

Array
(
    [title] => Order total
    [data] => $1,160.50
)
