我有这个数组数据:
Array
(
[0] => Array
(
[product_sequence] => 1
[quantity] => 1
[attributes] => Array
(
)
)
[1] => Array
(
[product_sequence] => 1
[quantity] => 1
[attributes] => Array
(
[Colour] => Black
)
)
)
通过product_sequence
我厌倦了:
array_search('1', $_SESSION["cart"])
但这根本不会返回任何数据

请尝试使用此
要查找符合搜索条件的值,您可以使用<div id="input"></div>
<div id="output"></div>
功能:
表示价值:
array_filter
表示密钥:
$searchword = '1';
$matches = array_filter($example, function($var) use ($searchword) { return preg_match("/\b$searchword\b/i", $var); })

您可以使用foreach
,也可以使用array_filter
。一个简化的例子:
<?php
$products = [
[
'product_sequence' => 1,
],
[
'product_sequence' => 1,
],
[
'product_sequence' => 2,
]
];
$productSequence = 1;
$filteredProducts = array_filter($products, function($product) use ($productSequence) {
// only return elements that test `true`
return $product['product_sequence'] === $productSequence;
});
print_r($filteredProducts);
收率:
Array
(
[0] => Array
(
[product_sequence] => 1
)
[1] => Array
(
[product_sequence] => 1
)
)
