I have a multidimensional array like this, I need to merge subarrays with the same messageID value.
$myarray = Array (
[0] => Array
(
[messageId] => 5ACE9D8841
[sender] => john#doe.com
)
[1] => Array
(
[messageId] => 7EE67D8170
[sender] => dan#doe.com
)
[2] => Array
(
[messageId] => 8095FD8836
[sender] => cat#doe.com
)
[3] => Array
(
[messageId] => 7EE67D8170
[dest] => mitch#doe.com
[status] => sent
[date] => 2021-02-01 11:06:55
)
);
Expected result , [1] and [3] are merged into [1] because they share the same [messageId] :
Array
(
[0] => Array
(
[messageId] => 5ACE9D8841
[sender] => john#doe.com
)
[1] => Array
(
[messageId] => 7EE67D8170
[dest] => mitch#doe.com
[status] => sent
[date] => 2021-02-01 11:06:55
[sender] => dan#doe.com
)
[2] => Array
(
[messageId] => 8095FD8836
[sender] => cat#doe.com
)
)
I don't mind about the key index or the order.
EDIT : I've tried array_merge, array_merge_recursive and many others. Best result was obtained with
foreach ($myarray as $sub_arr) {
$result_arr = array_merge($result_arr, $sub_arr);
$result_arr = array_unique($result_arr);
}
It works but returns only the last iteration :
Array
(
[messageId] => 7EE67D8170
[dest] => mitch#doe.com
[status] => sent
[date] => 2021-02-01 11:06:55
[sender] => dan#doe.com
)
Regards
Try using array_reduce function with callback function:
$result = array_values(array_reduce($myarray, function($rows, $item){
if (array_key_exists('messageId', $item) && is_scalar($item['messageId'])) {
$rows = array_replace_recursive($rows ?? [], [$item['messageId'] => $item]);
}
return $rows;
}));
print_r($result);

I have the following Multidimensional arrays
if($this->conn->row_count($sql)==true){
while($row=$statement->fetch()){
$problems[]=[
'order_id'=>$row['order_id'],
'details'=>['remark'=>$row['remark'],'date'=>$row['date']]
];
}
return $problems;
}
And then i print it out
echo '<pre>',print_r($problems),'</pre>';
Result
Array
(
[0] => Array
(
[order_id] => 4683
[details] => Array
(
[remark] => happy
[date] => 2018-06-09---10:16:41am
)
)
[1] => Array
(
[order_id] => 4683
[details] => Array
(
[remark] => unhappy
[date] => 2018-06-10---03:29:00am
)
)
[2] => Array
(
[order_id] => 4440
[details] => Array
(
[remark] => very unhappy
[date] => 2018-06-10---03:34:00am
)
)
)
I am trying to group them into a new Multidimensional Array if same order_id and join details. order_id could have more than 2 because there may more remarks on this order_id *just like the following
Array
(
[0] => Array
(
[order_id] => 4683
[details] => Array
(
[remark] => happy
[date] => 2018-06-09---10:16:41am
),
(
[remark] => unhappy
[date] => 2018-06-10---03:29:00am
)
)
[1] => Array
(
[order_id] => 4440
[details] => Array
(
[remark] => very unhappy
[date] => 2018-06-10---03:34:00am
)
)
)
For a clearer picture, please take a look at the screenshot
Any idea how to create a new array just like the Output?
You can group it by an associative array. You can use array_values to convert the associative array into a simple array.
$problems = [];
if($this->conn->row_count($sql)==true){
while($row=$statement->fetch()){
if ( !isset( $problems[ $row['order_id'] ] ) ) {
$problems[ $row['order_id'] ] = [
'order_id' => $row['order_id'],
'details' => []
];
}
$problems[ $row['order_id'] ]['details'][] = ['remark'=>$row['remark'],'date'=>$row['date']];
}
return array_values( $problems );
}
I have JSON arrays of objects. I am trying to sort an array using usort. I want to use value field from field_listing_order. It sorted using value. I am missing something but not able to figure it out. please review the code. Thanks!
stdClass Object
(
[node_title] => abc
[nid] => 2281
[field_api_order_value] => 201
[field_node_entity_type] => node
[_data] => Array
(
[nid] => Array
(
[entity_type] => node
[entity] => stdClass Object
(
[title] => abc
[field_listing_order] => Array
(
[und] => Array
(
[0] => Array
(
[value] => 8
[format] =>
[safe_value] => 8
)
)
)
)
)
)
)
stdClass Object
(
[node_title] => abc
[nid] => 2243
[field_api_order_value] => 204
[field_node_entity_type] => node
[_data] => Array
(
[nid] => Array
(
[entity_type] => node
[entity] => stdClass Object
(
[title] => abc
[field_listing_order] => Array
(
[und] => Array
(
[0] => Array
(
[value] => 3
[format] =>
[safe_value] => 3
)
)
)
)
)
)
) stdClass Object
(
[node_title] => abc
[nid] => 2431
[field_api_order_value] => 242
[field_node_entity_type] => node
[_data] => Array
(
[nid] => Array
(
[entity_type] => node
[entity] => stdClass Object
(
[title] => abc
[field_listing_order] => Array
(
[und] => Array
(
[0] => Array
(
[value] => 1
[format] =>
[safe_value] => 1
)
)
)
)
)
)
)
and So on ...
foreach ($view->result as $result) {
$node = $result->_data['nid']['entity'];
$listing_order = $node->field_listing_order[LANGUAGE_NONE][0];
.....
// code goes here and it works well. sorting issue
}
usort ($node->field_listing_order[LANGUAGE_NONE][0], function($a, $b){
return strcmp($a->value, $b->value);
}); ?>
If you need to sort all the nodes using the field_listing_order value, you need to compare the values along the full path, from the first object to the value:
usort($view->result, function($a, $b) {
$la = $a->_data['nid']['entity']->field_listing_order[LANGUAGE_NONE][0]['value'];
$lb = $b->_data['nid']['entity']->field_listing_order[LANGUAGE_NONE][0]['value'];
return $la - $lb ;
});
In this case $a and $b are two different nodes which could be compared. That why you should compare the field_listing_order's value of these nodes. The answer is working with $la- $lb
I am trying to get the 'name' value from within a 'nested array' I am not sure if thats the correct term in PHP.
Array (
[0] => Array
(
[event] => Array
(
[id] => 28140972
[name] => Northwich v Lincoln United FC
[countryCode] => GB
[timezone] => Europe/London
[openDate] => 2017-03-08T19:45:00.000Z
)
[marketCount] => 24
)
[1] => Array
(
[event] => Array
(
[id] => 28140974
[name] => Viimsi MRJK v Paide Linnameeskond II
[countryCode] => EE
[timezone] => Europe/London
[openDate] => 2017-03-08T17:00:00.000Z
)
[marketCount] => 24
)
}
I am trying to access the 'name' key of every item in the array, but struggling to do it. Any advice?
$arrayOfNames = array_map(function ($item) {
return $item['event']['name'];
}, $yourPreviousArray);
Test case:
>>> print_r($data)
Array
(
[0] => Array
(
[event] => Array
(
[id] => 1
[name] => James
)
)
[1] => Array
(
[event] => Array
(
[id] => 2
[name] => Jim
)
)
)
=> true
>>> array_map(function($item) {
... return $item['event']['name'];
... }, $data)
=> [
"James",
"Jim",
]
>>>
You can do something like this:
foreach ($array as $item) {
echo $item['event']['name'].'<br/>';
}
I want to get the value of 'GUID' with the value of 'SamAccountName'. i.e. I only have the value pf 'SamAccountName' and I would like to get the value of 'GUID' for that part of the array.

This was originally a stdClass object but I used json_decode(json_encode($obj), true) to convert to an associative array.
Sounds like you want to get the GUID portion for the value of 'SamAccountName'. Use a foreach loop:
function getGUID($san, $array) {
foreach($array as $a) {
if($a['SamAccountName'] == $san) {
return $a['GUID'];
}
}
return false;
}
$guid = getGUID("SamAccountNameHere", $yourArray);
You can use a simple loop to fetch it
$id = 0;
foreach($data as $item) {
if (isset($item['SamAccountName']) && 'accountName' == $item['SamAccountName']) {
$id = $item['GUID'];
break;
}
}
var_dump($id);
is this what you are looking for?
function findBySam($arrayList, $sam) {
foreach($arrayList as $array) {
if($array['SamAccountName'] == $sam) {
return $array;
}
}
return false;
}
Here is an example of a function that you could use. This assumes that there will be only one object with the SamAccountName that you supply in the array (it just uses the first one that it finds). It returns the GUID of the matching array and false if it cannot find an array with a matching SamAccountName.
function getGuidForSamAccountName($arr, $name) {
foreach ($arr as $elem) {
if ($elem['SamAccountName'] === $name) {
return $elem['GUID'];
}
}
return false; //No match found
}
You can use array_filter function of php:
http://php.net/manual/en/function.array-filter.php
example:
$GUID = "sample";
array_filter($array, "findElement");
function findElement($el) {
return $el["GUID"] == $_GLOBAL["GUID"];
}
Not a very elegant solution... but it should work.
I have a rather annoying array structure to work with and I need to sort it by any arbitrary key combination. 2 records are displayed below but multiple records with or without the same structure will be present when sorting is actioned.
Here are two records.
Array(
[0] => Array
(
[cid] => 1
[title] => Mr
[first_name] => Abet
[last_name] => Simbad
[emails] => Array
(
[374] => Array
(
[eid] => 374
[name] => ski lodge
[email] => simbad#skifree.com
)
[373] => Array
(
[eid] => 373
[name] => work
[email] => simbad#work.com
)
[375] => Array
(
[eid] => 375
[name] => personal
[email] => simbad#gmail.com
)
)
)
[1] => Array
(
[cid] => 2
[title] => Mrs
[first_name] => Angie
[last_name] => Stokes
[emails] => Array
(
[590] => Array
(
[eid] => 590
[name] => work
[email] => angie#gmail.com
)
)
)
So if I wanted to sort by email in ascending order in the emails array, how can I get the second complete record to come first in the result array? angie#gmail.com comes before simbad#....
Also Some records will not contain an emails array. They would be last in the result set.
Any help would be much appreciated.
The array shown is a cut down version but I have addresses, notes, phones and websites in the same annoying structure. Ideally I could sort with something like
$sort = array('emails','email')
$data = sort_data_func('ASC',$sort,$data);
But anything steps in the right direction will help. :)
Here's some code I have so far
$sort = array('emails','email');
foreach($contacts as $ckey => $c){
if(is_array($c[$sort[0]])){
foreach($c[$sort[0]] as $key1 => $sort0){
if($sort0[$sort[1]]!=''){
$res[$sort[0]][$ckey][$sort[1]][] = $sort0[$sort[1]];
}
}
}
}
print_r($res);
Which produces:
Array
(
[emails] => Array
(
[0] => Array
(
[0] => simbad#skifree.com
[1] => simbad#work.com
[2] => simbad#gmail.com
)
[1] => Array
(
[0] => angie#gmail.com
)
)
)
But I have no idea where to go from here.
EDIT
OK I have the records in the currect order now but how can I keep the initial record ID in the resulting array?
Here's what I'm using.
$direction=='ASC'
function cmp_asc($a, $b){
$key = current(array_keys($a));
sort($a[$key]);
$a[$key] = current($a[$key]);
sort($b[$key]);
$b[$key] = current($b[$key]);
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
function cmp_desc($a, $b){
$key = current(array_keys($a));
asort($a[$key]);
$a[$key] = current($a[$key]);
asort($b[$key]);
$b[$key] = current($b[$key]);
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
if($direction=='ASC'){
usort($res[$sort[0]], 'cmp_asc');
}else{
usort($res[$sort[0]], 'cmp_desc');
}
In
Array

One of the usort functions, combined with a self-written comparison function that detects the order in which two elements should be sorted, should do the trick.
