我离这个很近，我只能尖叫。
这就是我所追求的。我有两个数组。第一个是：
array("id", "txtLname", "txtFname");
二是：
Array
(
[0] => Array
(
[id] => 220
[RecordGUID] => 1233C9-1F7A15-E8A447-C56CB2-227C20-2829E0
[txtEmplid] => 5469857
[txtLname] => Jones
[txtFname] => Richard
[txtMname] =>
[txtEmail] => email address
[Reg_Pass] => umbra1234
[Reg_User] => user
[txtSecEmail] => user@gmail.com
[dtDOB] => 1979-02-28
[drpStatus] => STUDENT
[lstWaive] => 1
[ENTERED] => 2013-09-15 18:03:18
[Status] => 0
[Approvalcode] => 17dc8e7336f0e9fd3411a4d9617efe865c5744ac
[Approvaldate] => 2013-09-15 18:03:47
[Approved] => 1
)
[1] => Array
(
[id] => 221
[RecordGUID] => DD1E72-368879-68CFE2-E03010-ECE1B1-0974E9
[txtEmplid] => 4454688
[txtLname] => Mathews
[txtFname] => Richard
[txtMname] =>
[txtEmail] => user2@gmail.com
[Reg_Pass] => umbra1234
[Reg_User] => user
[txtSecEmail] => user3@gmail.com
[dtDOB] => 1979-02-28
[drpStatus] => STUDENT
[lstWaive] => 1
[ENTERED] => 2013-09-16 12:28:08
[Status] => 0
[Approvalcode] => 7182769e45dc38a3a747c4bdb128e2f0a8c658e4
[Approvaldate] =>
[Approved] => 0
)
[2] => Array
(
[id] => 222
[RecordGUID] => 40D8E7-04C600-30A829-8E26CC-498BBE-9D3DF6
[txtEmplid] =>
[txtLname] =>
[txtFname] =>
[txtMname] =>
[txtEmail] =>
[Reg_Pass] =>
[Reg_User] =>
[txtSecEmail] =>
[dtDOB] => 1979-02-28
[drpStatus] => STUDENT
[lstWaive] => 1
[ENTERED] => 2013-09-16 12:28:24
[Status] => 0
[Approvalcode] => 8d2c33f7b7d6ef620811dbc4358e8103346bfb59
[Approvaldate] =>
[Approved] => 0
)
)
我所需要做的就是遍历第二个数组并删除与第一个数组不匹配的项目。结果如下：
Array
(
[0] => Array
(
[id] => 220
[txtLname] => Method
[txtFname] => Richard
)
[1] => Array
(
[id] => 221
[txtLname] => Method
[txtFname] => Richard
)
[2] => Array
(
[id] => 222
[txtLname] => Method
[txtFname] => Richard
)
)
这是我到目前为止所做的。
foreach ($r as $reg) {
foreach($reg as $k => $v) {
if ($k == !in_array($k, $f)) {
echo $reg[$k];
}
}
}
我得到的回显响应是第一个数组中所有数据的列表，减去第一个数组中的字段。因此，它正在删除以下项目我想删除，但我似乎无法将其转换为正确的格式。
提前感谢您的帮助。
$arr1 = array("id"=>1, "txtLname"=>1, "txtFname"=>1)
$result = array();
// $arr2 = array 2 (check your code)
foreach ($arr2 as $el) {
$result[] = array_intersect_key($el, $arr1);
}
var_dump($result);
将
echo $reg[$k];替换为unset($reg[$k]);
