在多维数组中搜索值并保持键关联
[英]Search value in multidimension array and keep keys association
问题描述
I have this array converted from xml of webservice. 
我从Web服务的xml转换此数组。 I have 500 items in this array. 我有500个项目在这个数组中。 I want to search any value and return all found array items with key association ( similar to database select query ). 我想搜索任何值并返回具有键关联的所有找到的数组项（类似于数据库select查询）。 So if I search 'dummy' then it should return first item of this array. 因此，如果我搜索“虚拟”，则它应返回此数组的第一项。

I tried stripos to search string in array value and in_array based functions but either it gives incorrect result or key association is not maintained. 我尝试了stripos在基于数组值和基于in_array的函数中搜索字符串，但是它给出的结果不正确或键关联未得到维护。
I am unable to find a way to maintain key->value. 我找不到保持键->值的方法。
function search($array, $key, $value)
{
$results = array();
if (is_array($array))
{
if (isset($array[$key]) && $array[$key] == $value)
$results[] = $array;
foreach ($array as $subarray)
$results = array_merge($results, search($subarray, $key, $value));
}
return $results;
}
This may be worst function you have ever seen but this do the job. 这可能是您见过的最糟糕的功能，但是可以完成任务。 If some one can make it recursive ( array may be further deeper ). 如果有人可以使其递归（数组可能会更深）。
function search_in_multi_array($srchvalue, $array)
{
$foundkey = '';
if (is_array($array) && count($array) > 0)
{
foreach($array as $pkey => $pvalue)
{
foreach($pvalue as $ckey => $cvalue)
{
if (is_array($cvalue) && count($cvalue) > 0)
{
if(in_array($srchvalue,$cvalue))
{
$foundkey[$pkey][$ckey] = $cvalue;
}
foreach($cvalue as $dkey => $dvalue)
{
if(!is_array($dvalue))
{
$pos = stripos($dvalue, $srchvalue);
if ($pos !== false)
{
$foundkey[$pkey][$ckey] = $cvalue;
}
}
}
}
}
}
}
return $foundkey;
}
Function call - $needle = 'fox'; 函数调用-$ needle ='fox'; search_in_multi_array($needle, $my_array); search_in_multi_array（$ needle，$ my_array）; This is the output 这是输出

You may want to have a look at XPath to run queries against the "raw" XML, see DOMXPath for example. 您可能需要查看XPath才能针对“原始” XML运行查询，例如，请参阅DOMXPath 。
Something like /myRootTag/someDayTag[.//text()[contains(.,'MY_SEARCH_VALUE')]] should do the trick, selecting and returning all the someDayTag XML elements below the myRootTag which have the text MY_SEARCH_VALUE in any child node. 喜欢的东西/myRootTag/someDayTag[.//text()[contains(.,'MY_SEARCH_VALUE')]]应该做的伎俩，选择并返回所有someDayTag下面的XML元素myRootTag具有文本MY_SEARCH_VALUE任何子节点。

You can use array_search() function to look through the array values. 您可以使用array_search（）函数浏览数组值。 But array_search only looks in single-dimensional array. 但是array_search只看一维数组。
Since you have a multi-dimensional array, you can write custom recursive function to search recursively in the array 由于您具有多维数组，因此您可以编写自定义递归函数以在数组中递归搜索
function recursive_array_search($needle,$haystack) {
foreach($haystack as $key=>$value) {
$current_key=$key;
if($needle===$value OR (is_array($value) && recursive_array_search($needle,$value) !== false)) {
return $current_key;
}
}
return false;
}
But please note, using array_search() is a easier approach but not a optimised function. 但是请注意，使用array_search（）是更简单的方法，但不是优化的函数。 Which means if you're more concerned about your memory utilisation then I would also addtionally suggest. 这意味着，如果您更担心内存使用率，那么我也建议您。
- Create a new array say 'dictionary' and store them like
$dictonary[<key-searched>] = array('12.12.2014', '13.12.2014')创建一个名为'dictionary'的新数组，并将其存储为$dictonary[<key-searched>] = array('12.12.2014', '13.12.2014') - So you process them once, and cache them 因此，您只需处理一次并缓存它们
- So next time when you want search again for the same key, you can first check if the key exists in dictionary. 因此，下次要再次搜索相同的键时，可以首先检查该键是否存在于字典中。 If exists return from there, else use array_search and cache the results in dictionary 如果存在从那里返回，否则使用array_search并将结果缓存在字典中
Its always easier to search by key-value than to search in a multi-dimensional array. 通过键值进行搜索总是比在多维数组中进行搜索更容易。

I've made a simple routine that will extract the values in the array you're looking for: 我做了一个简单的例程，它将提取您要查找的数组中的值：
function search_keys($needle,$haystack)
{
foreach($haystack as $key => $value)
{
if (is_array($value)) $output[$key] = search_keys($needle,$value);
else if (strpos($value,$needle) !== FALSE) $output[$key] = $value;
}
return isset($output) ? $output : NULL; // prevent warning
}
echo '<pre>';
print_r(search_keys('garden',$data));
echo '</pre>';
This will return 'garden' as: 这将返回“花园”为：
Array
(
[12.12.2014] => Array
(
[7] => Array
(
[Type] => garden
)
)
)
You can further process the output of this function, or change the function, as needed. 您可以根据需要进一步处理此功能的输出，或更改功能。
