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 )
