在 Laravel 9 中,查找集合中的多个键值对的实现
1、现在集合格式如下
Illuminate\Support\Collection Object
(
[items:protected] => Array
(
[0] => Array
(
[id] => 77631
[name] => 客户姓名
[email] => 44445@163.com
[type] => 1
)
[1] => Array
(
[id] => 77630
[name] => 王某人2
[email] => 4444@163.com
[type] => 0
)
[2] => Array
(
[id] => 77629
[name] => 王某人
[email] => 44445@163.com
[type] => 1
)
[3] => Array
(
[id] => 77628
[name] => 王某某
[email] => 44445@163.com
[type] => 1
)
[4] => Array
(
[id] => 77627
[name] => 李某某
[email] => 4444@163.com
[type] => 1
)
)
[escapeWhenCastingToString:protected] =>
)
2、如果需要基于 id 查找,firstWhere 方法返回集合中具有给定键 / 值对的第一个元素
$customer = $customers->firstWhere('id', 77631);
print_r($customer);
exit;
Array
(
[id] => 77631
[name] => 客户姓名
[email] => 44445@163.com
[type] => 1
)
3、现在需要基于 name 与 email 这2个键值对查找。first 方法返回集合中通过给定真值测试的第一个元素。符合预期
$customer = $customers->first(function ($value, $key) {
return $value['name'] == '客户姓名' && $value['email'] == '44445@163.com';
});
print_r($customer);
exit;
Array
(
[id] => 77631
[name] => 客户姓名
[email] => 44445@163.com
[type] => 1
)
