根据条件在php中搜索并删除多维数组中的元素

Question

我有一个关于多dim数组的简单问题，我想删除任何redundent元素让我说在我的情况下，[serviceMethod] => PL来了2次，我想搜索'PL'关于{{ 1}}如果一个元素价格较低，我想保留它并删除数组中的另一个

[APIPriceTax]

）

这是我的伪代码：Array ( [0] => Array ( [carrierIDs] => 150 [serviceMethod] => CP [APIPriceTax] => 30.63 [APIPriceWithOutTax] 28.32 [APIServiceName] => Xpresspost USA [APIExpectedTransitDay] => 2 ) [1] => Array ( [carrierIDs] => 155 [serviceMethod] => PL [APIPriceTax] => 84.13 [APIPriceWithOutTax] => 73.8 [APIServiceName] => PurolatorExpressU.S. [APIExpectedTransitDay] => 1 ) [2] => Array ( [carrierIDs] => 164 [serviceMethod] => PL [APIPriceTax] => 25.48 [APIPriceWithOutTax] => 22.35 [APIServiceName] => PurolatorGroundU.S. [APIExpectedTransitDay] => 3 ) 是实际数组

$carrierAddedToList

Answer 1

由于没有in_array()搜索多维元素，因此需要构建一个由serviceMethod键入的关联数组。然后，您可以使用isset()检查我们是否已经拥有该方法的元素。

$newArray = array();
foreach ($carrierAddedToList as $cK) {
    $sm = $cK['serviceMethod'];
    if (!isset($newArray[$sm]) || $newArray[$sm]['APIPriceTax'] > $cK['ApiPriceTax']) {
        $newArray[$sm] = $cK;
    }
}
// Now convert associative array to indexed:
$newArray = array_values($newArray);
