我有两个数组:
Array
(
[0] => Array
(
[id] => 1
[type] => field
[remote_name] => Title
[my_name] => title
[default_value] => http%3A%2F%2Ftest.com
)
[1] => Array
(
[id] => 2
[type] => field
[remote_name] => BookType
[my_name] => book-type
[default_value] =>
)
[2] => Array
(
[id] => 3
[type] => value
[remote_name] => dvd-disc
[my_name] => dvd
[default_value] =>
)
)
Array
(
[title] => Test
[book-type] => dvd
)
我需要取第二个数组中的每个键,将其与第一个数组中my_name
的值匹配,并将其替换为第一个数组的相应remote_name
的值,同时保留第二个阵列的值。
一定有一些c array
zy函数可以提供帮助!
EDIT:在少数情况下,第二个数组的value
需要替换为第一个数组remote_name
的value
,其中第二个阵列的值与第一个阵列的my_name
的值匹配。我怎样才能做到这一点?
EG:book-type => dvd
应转变为BookType => dvd-disc
喜欢这样吗?:
$first = array(
array(
'id' => 1,
'type' => 'field',
'remote_name' => 'Title',
'my_name' => 'title',
'default_value' => 'http%3A%2F%2Ftest.com',
),
array(
'id' => 2,
'type' => 'field',
'remote_name' => 'BookType',
'my_name' => 'book-type',
'default_value' => '',
),
array(
'id' => 3,
'type' => 'value',
'remote_name' => 'dvd-disc',
'my_name' => 'dvd',
'default_value' => '',
),
);
$second = array(
'title' => 'Test',
'book-type' => 'dvd',
);
$map = array('fields' => array(), 'values' => array());
foreach ($first as $entry) {
switch ($entry['type']) {
case 'field':
$map['fields'][$entry['my_name']] = $entry['remote_name'];
break;
case 'value':
$map['values'][$entry['my_name']] = $entry['remote_name'];
break;
}
}
$new = array();
foreach ($second as $key => $val) {
$new[isset($map['fields'][$key]) ? $map['fields'][$key] : $key] = isset($map['values'][$val]) ? $map['values'][$val] : $val;
}
print_r($new);
输出:
Array
(
[Title] => Test
[BookType] => dvd-disc
)
解释:
第一个循环收集字段和值的my_name/remote_name对,并使它们更易于访问。像这样:
Array
(
[fields] => Array
(
[title] => Title
[book-type] => BookType
)
[values] => Array
(
[dvd] => dvd-disc
)
)
第二个循环将遍历CCD_ 10并使用其中的键/值对来填充CCD_。但这样做将检查$map
中的键/值是否重复。
未在映射中找到的键或值将按原样使用。
foreach($arr1 as &$el) {
$el['remote_name'] = $arr2[$el['my_name']];
}
unset($el);
我不知道这样一个c array
zy函数,但我知道如何做到:
//$array1 is first array, $array2 is second array
foreach($array1 as $key => $value){
if (isset($value['remote_name'], $value['my_name']) && $value['remote_name'] && $value['my_name']){
$my_name = $value['my_name'];
if (isset($array2[$my_name])) {
$remote_name = $value['remote_name'];
$array2[$remote_name] = $array2[$my_name];
//cleanup
unset($array2[$my_name]);
}
}
}
