I have a ldap request that returns an array, however the returned array is full of "counts" and odd pointers, as this application is an API designed to be used with Javascript on mobile devices, the less text there is the better.
What is the most efficient way to strip out all the values that don't have the key count? As well as the ones that just seem to be saying what the keys are (eg [0] => cn)?
Array
(
[status] => OK
[count] => 4
[results] => Array
(
[count] => 3
[0] => Array
(
[cn] => Array
(
[count] => 1
[0] => James Bee
)
[0] => cn
[umanprimaryou] => Array
(
[count] => 1
[0] => Awesome School
)
[1] => umanprimaryou
[ou] => Array
(
[count] => 2
[0] => School of Awesome
[1] => Faculty of Engineering
)
etc...
Aiming for
Array
(
[status] => OK
[results] => Array
(
[0] => Array
(
[cn] => Array
(
[0] => James Bee
)
[umanprimaryou] => Array
(
[0] => Awesome School
)
[ou] => Array
(
[0] => School of Awesome
[1] => Faculty of Engineering
)
etc...
For further explanation I am wanting to unset all the [count] => value pairs and if possible the values such as [0] => cn in the results array.
Untested code:
function strip_count(array $arr) {
foreach ($arr as $key => $value) {
if (is_array($arr[$key])) {
strip_count($arr[$key]);
} else {
if ($key == 'count') {
unset($arr[$key]);
}
}
}
}
Edit: I wrote this before you edited your question, but it shouldn't be too hard to modify this recursive function to strip out the other things you wish to remove as well.
Might wanna look into using array_walk_recursive and check if $key == 'count' in your user defined function.

)
So I have tried many times but the desired output is not coming . please help me out how to get the desired output.
It seemed like that answer could be modified, or put in a function that you could call multiple times if needed to combine more than two arrays.
There's probably cleaner ways to handle this with array functions like array_merge or array_walk, but this is the general idea of how I might approach it. I haven't tested this, but maybe it's useful.
foreach($first as $key1 => $value){
foreach($second as $key2 => $value2){
// match the ids and check if array key exists on first array
if($value['id'] === $value2['id'] && empty($first[$key2])){
$first[$key][$key2] = $value2;
}
}
}
EDIT: Based on the answer you posted vs the question you asked, are you incrementing the collection numbers or just setting them? In other words why use +=? You should also be able to remove array_merge and array_push.
Below is geared more towards what you're trying to do. I haven't tested this either, but if you run into errors, post your code with the errors returned so that it's easier to debug:
foreach($ids as $k)
{
$thisArray = $newArray[] = array("id"=>$k->id,"name"=>$k->name);
foreach($q1 as $k1)
{
if($k->id == $k1->id && !empty($k1->mcollecton))
{
$thisArray['mc'] = $k1->mcollecton;
}
}
foreach($q2 as $k2)
{
if($k->id == $k2->id && !empty($k2->dcollecton))
{
$thisArray['dc'] = $k2->dcollecton;
}
}
}
// This should have both new collections fields on all array items
print_r($newArray)
I have an array like the following. This is the results of a query on one of our servers.
Array
(
[count] => 1
[0] => Array
(
[name] => Array
(
[count] => 1
[0] => mac
)
[0] => name
[staffid] => Array
(
[count] => 1
[0] => 1234
)
[1] => staffid
[school] => Array
(
[count] => 1
[0] => western
)
[2] => school
[count] => 3
[dn] => cn=mac,cn=staff
)
)
How do I loop through this array and create a new array as follows.
Array
(
[name] => mac
[staffid] => 1234
[school] => western
)
I've tried a foreach loop echoing the key & values, but I'm not sure where to go from there. There will be more results returned as the query is expanded, but original array layout will be the same and the new layout needs to be the same format.
Any ideas ?
Thanks
Try this:
$result = array();
foreach($yourArray as $element){
for($i=0;$i<$element['count']; $i++){
unset($element[$element[$i]]['count']);
$result[$element[$i]] = implode(', ', $element[$element[$i]]);
}
}
I have a multi-dimensional array that I would like to get unique sub-values from, but also have a count of how many times those unique sub-values occurred.
For instance, this would be my starting array:
[0] => Array
(
[0] => Array
(
[id] => 1533438473619168
)
[1] => Array
(
[id] => 3333333333333333
)
)
[1] => Array
(
[0] => Array
(
[id] => 1533438473619168
)
[1] => Array
(
[id] => 5555555555555555
)
)
[2] => Array
(
[0] => Array
(
[id] => 1533438473619168
)
[1] => Array
(
[id] => 77777777777777777
)
)
In the end, I'd like to have an array that looks like this:
[0] => Array
(
[0] => Array
(
[id] => 1533438473619168
[count] => 3
)
[1] => Array
(
[id] => 3333333333333333
[count] => 1
)
[2] => Array
(
[id] => 5555555555555555
[count] => 1
)
[3] => Array
(
[id] => 77777777777777777
[count] => 1
)
)
Is there any general/easy way to do this without iterating through the first array for each value, comparing/storing the values in a temporary array, checking them, and adding to the count?
To get this exact format you may need to iterate thought your current array and do the counting manually, however php has the array_count_values() and array_unique() functions for this kind of thing:
http://php.net/manual/en/function.array-count-values.php
http://php.net/manual/en/function.array-unique.php
Because you are only concerned with the deepest values of the array, using array_walk_recursive seems suitable for this. Note that a reference to the output array $counted is used in the callback.
array_walk_recursive($ids, function($id, $k) use (&$counted) {
$counted[$id] = isset($counted[$id]) ? $counted[$id] + 1 : 1;
});
Using the id as the key in the $counted array will simplify the counting. The result of this will be somewhat different from your suggested output, but in my opinion it would actually be simpler to use. (e.g. foreach ($counted as $id => $count) {...).
$counted = array(
"1533438473619168" => 3
"3333333333333333" => 1
"5555555555555555" => 1
"77777777777777777" => 1);
I've spent the day playing with deceze's answer but I'm no closer to making it work. I may have part of it, but not sure how to get recursion in array_filter.
My Array looks like this (sample):
Array
(
[name] => root
[ChildCats] => Array
(
[0] => Array
(
[name] => Air Conditioning
[ChildCats] => Array
(
[0] => Array
(
[name] => Ducted Air Conditioning
[ChildCats] => Array
(
[0] => Array
(
[name] => Supply & Install
[ChildCats] => Array
(
[0] => Array
(
[name] => Daiken
[S] => 6067
)
)
)
[1] => Array
(
[name] => Supply Only
[ChildCats] => Array
(
[0] => Array
(
[name] => Mitsubishi
[S] => 6026
)
)
)
)
)
[1] => Array
(
[name] => Split System Air Conditioning
[ChildCats] => Array
(
[0] => Array
(
[name] => Supply & Install
[ChildCats] => Array
(
[0] => Array
(
[name] => Daiken
[S] => 6067
)
[1] => Array
(
[name] => Fujitsu Split Air Conditioning Systems
[S] => 6464
)
[2] => Array
(
[name] => Mitsubishi Electric Split Air Conditioning Systems
[S] => 6464
)
)
)
)
)
)
)
[1] => Array
(
[name] => Appliance / White Goods
[ChildCats] => Array
(
[0] => Array
(
[name] => Clearance
[S] => 6239
)
[1] => Array
(
[name] => Cooktops
[ChildCats] => Array
(
[0] => Array
(
[name] => Ceramic Cooktops
[S] => 6239
)
[1] => Array
(
[name] => Element Cooktops
[S] => 6067
)
[2] => Array
(
[name] => Gas Cooktops
[S] => 6239
)
[3] => Array
(
[name] => Induction Cooktops
[S] => 6239
)
)
)
)
)
Now lets say I try to extract just the parts of the array relevent to the following keypair:
S => 6067.
I'd like the result to look like:
Array
(
[name] => root
[ChildCats] => Array
(
[0] => Array
(
[name] => Air Conditioning
[ChildCats] => Array
(
[0] => Array
(
[name] => Ducted Air Conditioning
[ChildCats] => Array
(
[0] => Array
(
[name] => Supply & Install
[ChildCats] => Array
(
[0] => Array
(
[name] => Daiken
[S] => 6067
)
)
)
)
)
[1] => Array
(
[name] => Split System Air Conditioning
[ChildCats] => Array
(
[0] => Array
(
[name] => Supply & Install
[ChildCats] => Array
(
[0] => Array
(
[name] => Daiken
[S] => 6067
)
)
)
)
)
)
)
[1] => Array
(
[name] => Appliance / White Goods
[ChildCats] => Array
(
[0] => Array
(
[name] => Cooktops
[ChildCats] => Array
(
[0] => Array
(
[name] => Element Cooktops
[S] => 6067
)
)
)
)
)
)
)
What I cannot get my head arround is should I be creating a new array or using array filter.
Playing with deceze code I've got the search working using the following:
function recursive_assoc_in_array(array $haystack, array $needle, $childKey = 'ChildCats') {
if (array_intersect_assoc($haystack, $needle)) {
echo "Found via array_intersect_assoc ".$haystack[name]."\n";
return true;
}
foreach ($haystack[$childKey] as $child) {
if (recursive_assoc_in_array($child, $needle, $childKey)) return true;
}
return false;
}
But if I try to process with,
$array = array_filter($array, function (array $values) {
return recursive_assoc_in_array($values, array('S' => '6067'));
});
I get the original array which leads me to think I have to get recursion running on the array_filter query.
At this point I just go blank.
Additionally, the array keys will need to be reindexed on the produced new array. Any ideas?
--Additional 7/7/14
How about if I try to build a new array from the old one?
I'm trying:
function exploreArrayandAdd($Array) {
if ($Array['ChildCats']) {
foreach ($Array['ChildCats'] as $key => $value) {
$NewArray['ChildCats'][] = exploreArrayandAdd($value);
}
} else {
if ($Array['S'] == 6026) {
//echo "1";
return $Array;
}
}
}
But cannot work out how to pass the new array out of the function?
Tried removing branches that don't match using:
function exploreArray(&$Array) {
if ($Array['ChildCats']) {
foreach ($Array['ChildCats'] as $key => $value) {
$result = exploreArray($Array['ChildCats'][$key]);
if ($result === false)
unset($Array['ChildCats'][$key]);
}
} else {
// print_r($Array);
if ($Array['S'] == 6026) {
return true;
} else {
unset($Array);
return false;
}
}
//if ($NoChildCat==true) print_r($Array);
}
But I believe it is the wrong way as it does work at the bottom of the array but not back up towards the top as siblings make result true.
Also this won't reindex the array keys.
function recursive_array_filter(array $array, $childKey, callable $test) {
if (isset($array[$childKey]) && is_array($array[$childKey])) {
foreach ($array[$childKey] as $key => &$child) {
if (!$child = recursive_array_filter($child, $childKey, $test)) {
unset($array[$childKey][$key]);
}
}
if (!$array[$childKey]) {
unset($array[$childKey]);
}
}
return !empty($array[$childKey]) || $test($array) ? $array : [];
}
$array = recursive_array_filter($array, 'ChildCats', function (array $array) {
return array_intersect_assoc($array, ['S' => 6026]);
});
To express the algorithm in words: you descend down into the array first, following all ChildCats branches to their end. In each level you return the values as they are back to the caller if they match your test or if they have children, or you return an emptied array (you could also return false if you prefer). If some child turns out empty, you prune it with unset.
I have implemented the test as a callback function here for best reusability of the code.
I am trying to write some php code to process the second dimension's value of an array based on similar values of the first dimension values.
Following is the sample output.
[0] => Array (
[0] => 1
[1] => 0.091238491238491
)
[1] => Array (
[0] => 2
[1] => 0.2221793635487
)
[2] => Array (
[0] => 2
[1] => 0.10662717512033
)
[3] => Array (
[0] => 4
[1] => 0.44354338998346
)
[4] => Array (
[0] => 6
[1] => 0.2248243559719
)
[5] => Array (
[0] => 6
[1] => 0.31764705882353
)
[6] => Array (
[0] => 6
[1] => 0.15764625384879
)
[7] => Array (
[0] => 6
[1] => 0.19160083160083
)
[8] => Array (
[0] => 12
[1] => 0.31054875069499
)
[9] => Array (
[0] => 12
[1] => 0.10915034227918
)
[10] => Array (
[0] => 15
[1] => 0.32915461266474
)
//...........goes to 46000 elements
Now what I want to do is, if the index 0 values of each array is similar then I want to add the index 1's value.
So for example, if 0 index values for 4 arrays are same , I want to add index 1 values of all 4 arrays.
If there is a unique value on 0th index, dont add it with anything, simply store index 1's value and move on.
Thanks very much.

$added = array();
foreach ($array as $item) {
if (isset($added[$item[0]])) {
$added[$item[0]] += $item[1];
} else {
$added[$item[0]] = $item[1];
}
}
$p=0;
$temp = $final_prod_ex[0][1];
for($x=0; $x<count($final_prod)-1; $x++){
if($final_prod_ex[$x][0]==$final_prod_ex[$x+1][0]){
$temp = $temp + $final_prod_ex[$x+1][1];
}
else{
$ans[$p] = $temp." ".$final_prod_ex[$x][0];
$temp = $final_prod_ex[$x+1][1];
$p++;
}
}
Finally figured it out after a lot of thinking(I'm new to programming)...Array's name is $final_prod_ex. Comment on this if I can make it better. And sorry #deceze. I could not understand your solution. I know you were trying to give the value of one array as an index to another. But what the scenario is, that value isnt like 0,1,2,3,4.... Its like 1,3,5,6,7,10. We are missing numbers in between. Maybe I didnt understand your solution. Correct me if I am wrong.
Thanks for all the help.
