三维关联数组如下所示。
Array
(
[COL] => Array
(
[0] => Array
(
[emp_num] => 1000001
[user_name] => Test User
[amount] => 775.00
[name] => COL
)
[1] => Array
(
[emp_num] => 26
[user_name] => John Doe
[amount] => 555.00
[name] => COL
)
)
[RA. 20%] => Array
(
[0] => Array
(
[emp_num] => 1000001
[user_name] => Test User
[amount] => 110.00
[name] => RA. 20%
)
)
[BS] => Array
(
[0] => Array
(
[emp_num] => 1000001
[user_name] => Test User
[amount] => 444.00
[name] => BS
)
)
)
我想删除每个最内部数组的最后一对key=>value。（要删除键具有[名称]的键值对）结果应该像下面的数组。
Array
(
[COL] => Array
(
[0] => Array
(
[emp_num] => 1000001
[user_name] => Test User
[amount] => 775.00
)
[1] => Array
(
[emp_num] => 26
[user_name] => John Doe
[amount] => 555.00
)
)
[RA. 20%] => Array
(
[0] => Array
(
[emp_num] => 1000001
[user_name] => Test User
[amount] => 110.00
)
)
[BS] => Array
(
[0] => Array
(
[emp_num] => 1000001
[user_name] => Test User
[amount] => 444.00
)
)
)
我为此写了一个函数。
<!-- language: php -->
function remove_name_from_psa($psa_array){
foreach( $psa_array as $key=>$value ) {
foreach( $value as $key2=>$value2 ){
foreach( $value2 as $key3=>$value3 ){
if( $key3 != 'name') {
$psa_name_removed[$key][$value[$key2][$value2[$key3]]] = $value3;
}
}
}
}
return $psa_name_removed;
}
返回的数组是这样的，这显然不是我所需要的。
Array ( [COST OF LIVING] => Array
( [] => 555.00 )
[RENT ALLOW. 20%] => Array
( [] => 110.00 )
[BASIC SALARY] => Array
( [] => 444.00 )
)
还有很多未定义的偏移量和未定义的索引通知$psa_name_removed[$key][$value[$key2][$value2[$key3]]] = $value3;//这是我弄错的线路吗？或者整个方法是错误的？：-P
我怎样才能让它发挥作用？有人能帮忙吗
非常感谢。
function remove_name_from_psa($psa_array){
foreach( $psa_array as $key => $value ) {
foreach( $value as $key2 => $value2 ){
unset( $psa_array[$key][$key2]['name'] );
}
}
return $psa_array;
}
Wee，功能解决方案！
$array = array_map(function ($i) {
return array_map(function ($j) {
return array_diff_key($j, array_flip(array('name')));
}, $i);
}, $array);
更传统的解决方案：
foreach ($array as &$i) {
foreach ($i as &$j) {
unset($j['name']);
}
}
注意as &$i中的&。使用此引用来修改项目。
foreach($array as &$foo){
foreach($foo as &$bar){
unset($bar['name']);
}
}
要真正取消设置3D阵列中的最后一个元素，您需要执行以下操作：
$data = array(
array(
array(1, 2, 3),
),
);
foreach ($data as $i1 => $j1) {
foreach ($j1 as $i2 => $j2) {
end($j2);
unset($data[$i1][$i2][key($j2)]);
}
}
var_dump($data);
点击此处查看实际操作：

function remove_name_from_psa( $psa_array ){
foreach( $psa_array as $key => $value ) {
foreach( $value as $key2 => $value2 ) {
array_pop( $psa_array[$key][$key2] );
}
}
return $psa_array;
}
