我知道已经回答了这个问题,但是我在代码中使用了它并对其进行了扩展,以便您不必仅通过uid进行搜索。我只想与可能需要此功能的其他任何人共享它。
这是我的示例,请记住这是我的第一个答案。我删除了param数组,因为我只需要搜索一个特定的数组,但是您可以轻松地添加它。
同样,在我的情况下,由于其他字段可能不是唯一的,因此可能有多个键要返回。
/**
* @param array multidimensional
* @param string value to search for, ie a specific field name like name_first
* @param string associative key to find it in, ie field_name
*
* @return array keys.
*/
function search_revisions($dataArray, $search_value, $key_to_search) {
// This function will search the revisions for a certain value
// related to the associative key you are looking for.
$keys = array();
foreach ($dataArray as $key => $cur_value) {
if ($cur_value[$key_to_search] == $search_value) {
$keys[] = $key;
}
}
return $keys;
}
后来,我最终编写了此代码,以允许我搜索另一个值和关联键。因此,我的第一个示例允许您在任何特定的关联键中搜索值,然后返回所有匹配项。
其中一个值(“泰勒”)在一定的关联键(FIRST_NAME)发现第二个例子说明你和另一个值(true)的另一关联键(使用)被发现,并返回所有匹配(钥匙里的人与名字使用“泰勒” AND)。
/**
* @param array multidimensional
* @param string $search_value The value to search for, ie a specific 'Taylor'
* @param string $key_to_search The associative key to find it in, ie first_name
* @param string $other_matching_key The associative key to find in the matches for employed
* @param string $other_matching_value The value to find in that matching associative key, ie true
*
* @return array keys, ie all the people with the first name 'Taylor' that are employed.
*/
function search_revisions($dataArray, $search_value, $key_to_search, $other_matching_value = null, $other_matching_key = null) {
// This function will search the revisions for a certain value
// related to the associative key you are looking for.
$keys = array();
foreach ($dataArray as $key => $cur_value) {
if ($cur_value[$key_to_search] == $search_value) {
if (isset($other_matching_key) && isset($other_matching_value)) {
if ($cur_value[$other_matching_key] == $other_matching_value) {
$keys[] = $key;
}
} else {
// I must keep in mind that some searches may have multiple
// matches and others would not, so leave it open with no continues.
$keys[] = $key;
}
}
}
return $keys;
}
使用功能
$data = array(
array(
'cust_group' => 6,
'price' => 13.21,
'price_qty' => 5
),
array(
'cust_group' => 8,
'price' => 15.25,
'price_qty' => 4
),
array(
'cust_group' => 8,
'price' => 12.75,
'price_qty' => 10
)
);
$findKey = search_revisions($data,'8', 'cust_group', '10', 'price_qty');
print_r($findKey);
结果
Array ( [0] => 2 )
