I have a big array like this this one (only 5 entries here)
Array
(
[1] => Array
(
[last_token] => atokenforexample
[idmembre] => 31800
[key] => 821fbe3f4623649562f75a3de132c908
[idmembre_mobile] => 230106
)
[2] => Array
(
[last_token] => atoken1
[idmembre] => 83586
[key] => 0854ea148c95c08a30c623a313e645a9
[idmembre_mobile] => 126634
)
[3] => Array
(
[last_token] => atoken1
[idmembre] => 138727
[key] => 622c0803a8f662c1df852001017b5db8
[idmembre_mobile] => 119326
)
[4] => Array
(
[last_token] => atokensocool
[idmembre] => 163737
[key] => 8bab884bf46c14abfceaef7abcdf14f9
[idmembre_mobile] => 222066
)
[5] => Array
(
[last_token] => WOWanothetoken
[idmembre] => 236345
[key] => 41c17896091d9417b305e70541039249
I need to get a unique array from this on only one column, the last_token :
So here i need to swipe the array with key 3 (array[3]) because his last_token is the same as array[2][last_token].
Array unique can't work here.. :(
To save the last occurrence:
foreach($array as $value) {
$result[$value['last_token']] = $value;
}
$result = array_values($result);
Or to save the first occurrence:
foreach(array_reverse($array) as $value) {
$result[$value['last_token']] = $value;
}
$result = array_reverse(array_values($result));
Probably a more elegant way but I'm starving and off to eat.

I have two array. array one and array two. I want to merge these array into single array with key. My output result is valid but sequence is not correct.
Array one
Array
(
[0] => test-685f1e7bc357187e449479d627100102
[1] => test-685f1e7bc357187e449479d627d29390

Array two

[1] => DF955298-A664-4FA7-9586-FCD4CF988888
)
Expected Result
Array
(
[0] => Array
(
[key] => test-685f1e7bc357187e449479d627100102
[uuid] => DF955298-A664-4FA7-9586-FCD4CF977777

[uuid] => DF955298-A664-4FA7-9586-FCD4CF988888
)
)
My code is for that result is mentioned below:
$record = array();
foreach ($keys_array as $key => $all_key) {
foreach ($uuid_array as $uuid_key => $all_uuid) {
$record[$key]['key'] = $all_key;
$record[$uuid_key]['uuid'] = $all_uuid;
}
}
My output sequence is not valid. Where is the problem
Array

[0] => Array
(
[key] => test-685f1e7bc357187e449479d627100102

)
)
Simple solution:
$record = array();
foreach ($keys_array as $key => $all_key) {
$record[] = [
'key' => $all_key,
// get value under the same key from `$uuid_array`
'uuid' => $uuid_array[$key],
];
}
I have an array which is as follows:
Array
(
[0] => Array
(
[postId] => 105
[postTitle] => Test
[postNonArray] => Subzero
[postDesc] => Array
(
[0] => Array
(
[para] => Subzero
[align] => L
)
)
[postDate] => 25.08.2016
[postTime] => 13:44

[1] => Array
(
[postId] => 106
[postTitle] => Test 2
[postNonArray] => Test
[postDesc] => Array

[2] => Array

[postVideo] =>
)
)
As you can see, there is two post details with postId=106;
How can I remove the redundant data from the array based on postId?
The project is on PHP.
I think this is what you are trying to achieve:-
$array = array_map("unserialize", array_unique(array_map("serialize", $array)));
echo "<pre/>";print_r($array);
Check output(whole code with your original array):- https://eval.in/630678
Note:- It will remove the duplicate values (so whole duplicate array will gone as you asked in comment)
I would suggest loop like the one below. It will go through all the elements from $your_array_name and will make an unique array of id where we will store the postIds. We will also check if there are duplicated in the $unique_ids array, and if so we will remove that duplicate element.
$unique_ids = array();
foreach($your_array_name as $key => $value){
//check if the postId is in the array of the unique ids
if(!in_array($value['postId'], $unique_ids)()){
array_push($unique_ids,$value['postId']); //if it is not - push it there
} else {
unset($your_array_name($key)); //if it is - remove the whole element from the array
}
}
You will need to loop the data and create a new array with unique values so here you go:
$ShowNewArray = array();
foreach($array as $key => $value){
if(!array_key_exists('postId', $ShowNewArray)){
$ShowNewArray[$value['postId']] = $value;
}
}
print_r($ShowNewArray);
Hope it will help you.
I am new in PHP and love to learn it.
I want to merge two or more arrays having same keys only. And neglect the arrays whose keys are not in both the Arrays. Like
Here is the First Array :
Array
(
[1] => Array
(
[111] => 36265
)
[2] => Array
(
[222] => 36265
)
[3] => Array
(
[333] => 36265
)
)
and Second Array as :
Array
(
[1] => Array
(
[444] => 36265
)
[2] => Array
(
[555] => 36265
)
[4] => Array
(
[666] => 36265
)
)
And i want my result to be as :
Array
(
[1] => Array
(
[111] => 36265
[444] => 36265
)
[2] => Array
(
[222] => 36265
[555] => 36265
)
)
Neglecting the rest Array with key [3] & [4]....
So Please anyone tell me how to get this. I try out "array_merge_recursive()" but this one displays all keys.
Thanks in advance.
You'd have to loop over one of the arrays, check for the existence of the current key in the other array, if it exists, merge them, eg:
$output = array();
foreach ($array1 as $key => $value) {
if (array_key_exists($key, $array2)) {
$output[$key] = $value + $array2[$key];
}
}
Here's a demo
You're probably looking for array_intersect_key.
You could also use a foreacah loop and create a new one. While in this loop you can use one of the arrays keys to match them both. Consider this example:
$array1 = array( 1 => array(111 => 36265), 2 => array(222 => 36265), 3 => array(333 => 36265), ); $array2 = array( 1 => array(444 => 36265), 2 => array(555 => 36265), 4 => array(666 => 36265), );
$new_array = array();
foreach($array1 as $key => $value) {
if(isset($array2[$key])) {
$new_array[$key][key($array1[$key])] = reset($array1[$key]);
$new_array[$key][key($array2[$key])] = reset($array2[$key]);
}
}
echo '<pre>';
print_r($new_array);
echo '</pre>';
Should yield something like this:
Array
(
[1] => Array
(
[111] => 36265
[444] => 36265
)
[2] => Array
(
[222] => 36265
[555] => 36265
)
)
Is there a way to delete a dimension in a array (only if it's empty), it's pretty dificult to explain with words, so that's what i want to do :
I have an array that returns :
(
[region1] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
)
I want it to be :
(
[region1] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
foreach($array as $key => $value) {
$array[$key] = reset($value);
}
That will replace each value in the outer array with the first element of that value.
how can i count an element if it appears more than once in the same array?
I already tried with array_count_values, but it did not work, is it beacuse i got more than one key and value in my array?
This is my output from my array (restlist)
Array (
[0] => Array ( [restaurant_id] => 47523 [title] => cafe blabla)
[1] => Array ( [restaurant_id] => 32144 [title] => test5)
[2] => Array ( [restaurant_id] => 42154 [title] => blabla2 )
[3] => Array ( [restaurant_id] => 32144 [title] => test5)
[4] => Array ( [restaurant_id] => 42154 [title] => blabla2 )
)
I want it to count how many times the same element appears in my array and then add the counted value to my newly created 'key' called hits in the same array.
Array (
[0] => Array ( [restaurant_id] => 47523 [title] => cafe blabla [hits] => 1)
[1] => Array ( [restaurant_id] => 32144 [title] => test5 [hits] => 2)
[2] => Array ( [restaurant_id] => 42154 [title] => blabla2 [hits] => 2)
)
This is how i tried to do what i wanted.
foreach ($cooltransactions as $key)
{
$tempArrayOverRestaurants[]= $key['restaurant_id'];
}
$wordsRestaruants = array_count_values($tempArrayOverRestaurants);
arsort($wordsRestaruants);
foreach ($wordsRestaruants as $key1 => $value1)
{
$temprestaurantswithhits[] = array(
'restaurant_id' => $key1,
'hits' => $value1);
}
foreach ($restlistas $key)
{
foreach ($temprestaurantswithhits as $key1)
{
if($key['restaurant_id'] === $key1['restaurant_id'])
{
$nyspisestedsliste[] = array(
'restaurant_id' => $key['restaurant_id'],
'title' => $key['title'],
'hits' => $key1['hits']);
}
}
}
I know this is probably a noob way to do what i want but i am still new at php..I hope you can help
Just try with associative array:
$input = array( /* your input data*/ );
$output = array();
foreach ( $input as $item ) {
$id = $item['restaurant_id'];
if ( !isset($output[$id]) ) {
$output[$id] = $item;
$output[$id]['hits'] = 1;
} else {
$output[$id]['hits']++;
}
}
And if you want to reset keys, do:
$outputWithoutKeys = array_values($output);
