I have a multidimensional array in php and i need to change the column order with the order of a second simple array.
EDIT:
Although both arrays are the same in regard of values and keys, im using this for export with phpexcel, and it generates the xls file with the order of the given array. I need to change that order so the xls file looks that way.
The array looks like this:
Array
(
[0] => Array
(
[name] => Name1
[sn] => Sn1
[somenumber] => 43234234
)
[1] => Array
(
[name] => Name2
[sn] => Sn2
[somenumber] => 4564564
)
[2] => Array
(
[name] => Name3
[sn] => Sn3
[somenumber] => 6575647456745
)
)
And the second array is this:
Array
(
[0] => sn
[1] => name
[2] => somenumber
)
What i need is the first array to be ordered based on the second so it looks like this:
Array
(
[0] => Array
(
[sn] => Name1
[name] => Sn1
[somenumber] => 43234234
)
[1] => Array
(
[sn] => Name2
[name] => Sn2
[somenumber] => 4564564
)
[2] => Array
(
[sn] => Name3
[name] => Sn3
[somenumber] => 6575647456745
)
)
this is how you can sort your array:
$template array:
//template array
$reference = array('sn', 'name', 'somenumber');
$array_to_sort = Array
(
"0" => Array
(
"somenumber" => "Name1",
"sn" => "Sn1",
"name" => "43234234"
),
"1" => Array
(
"sn" => "Name2",
"somenumber" => "4564564",
"name" => "Sn2"
),
"2" => Array
(
"sn" => "Name3",
"name" => "Sn3",
"somenumber" => "6575647456745"
)
);
$ordered_array = [];
foreach ($array_to_sort as $key => $value) {
$ordered_array[] = array_replace(array_flip($reference), $value);
}
print_r($ordered_array);
If all keys always present
// Make template array with correct order of keys
$template = array_flip($second);
foreach($array as &$x) {
// replace values in template
$x = array_replace($template, $x);
}

I'm using print_r(array_unique($array, SORT_REGULAR)); on the array below but it does not work.
I'm trying to filter out the redundant data.
Notice that [Order] and its key value pairs are all the same. But [Transaction] and its key value pairs are unique.
I need to get the [Order] element data and combine it with the 3 different [Transaction] elements.
My array
Array
(
[0] => Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[TransPO] => TR11211
[TransactionPrice] => 91.17
)
)
[1] => Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[TransPO] => TR11212
[TransactionPrice] => 180.41
)
)
[2] => Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[TransPO] => TR11213
[TransactionPrice] => 209.99
)
)
)
The final array I need will look something like this.
Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[0] => Array
(
[TransPO] => TR11211
[TransactionPrice] => 91.17
)
[1] => Array
(
[TransPO] => TR11212
[TransactionPrice] => 180.41
)
[2] => Array
(
[TransPO] => TR11213
[TransactionPrice] => 209.99
)
)
)
I can flatten the original array and then use array_unique, but wanted to see if there is a better way to accomplish what I need.
my code:
$myarray = array(
0 => array(
"Order" => array("PO" => "TR11214", "OrderID" => 242856952012),
"Transaction" => array("TransPO" => "TR11211", "TransactionPrice" => 91.17)
),
1 => array(
"Order" => array("PO" => "TR11214", "OrderID" => 242856952012),
"Transaction" => array("TransPO" => "TR11212", "TransactionPrice" => 180.41)
),
2 => array(
"Order" => array("PO" => "TR11214", "OrderID" => 242856952012),
"Transaction" => array("TransPO" => "TR11213", "TransactionPrice" => 209.99)
)
);
print_r(array_unique($myarray, SORT_REGULAR));
If you want to determine how many unique values of the Order element there are in your array, you need to apply array_unique only to the Order elements, which you can do using array_column:
$unique_orders = count(array_unique(array_column($myarray, 'Order'), SORT_REGULAR));
You can process your array using a list of keys which have non-unique values to generate an array, while other keys will have just a single value:
$non_unique_keys = ['Transaction'];
$output = array();
foreach (array_keys($myarray[0]) as $key) {
if (in_array($key, $non_unique_keys)) {
$output[$key] = array_column($myarray, $key);
}
else {
$output[$key] = $myarray[0][$key];
}
}
print_r($output);
Example Output:
Array (
[Order] => Array (
[PO] => TR11214
[OrderID] => 242856952012
)
[Sales Tax] => Array (
[PO] => TR11214
[SalesTaxAmount] => 0
)
[Transaction] => Array (
[0] => Array (
[TransPO] => TR11211
[TransactionPrice] => 91.17
)
[1] => Array (
[TransPO] => TR11212
[TransactionPrice] => 180.41
)
[2] => Array (
[TransPO] => TR11213
[TransactionPrice] => 209.99
)
)

array_unique() is intended for single dimensional arrays. If you want to use it on a multi-dimentional array, you should consider using usort() instead. Then you'll need to iterate through the array in reverse manually, searching for duplicates and removing them.
I've tried some solutions from:
In PHP, how do you change the key of an array element?
php array from multidimensional array keys values
But its is not exacly what i need, i tried to mix some solutions but notting helped.
I have an array from my database:
Array (
[0] => Array (
[ID] => 1
[USER_ID] => 1
[DATA] => UNIQUE
[VALUE] => buuu )
[1] => Array (
[ID] => 2
[USER_ID] => 1
[DATA] => NICKNAME
[VALUE] => NoAd ) )
And i want to transform that database to:
Array (
[UNIQUE] => buuu
[NICKNAME] => NoAd
[any new [2]...[3]... from previous array
after that code:
foreach($playerdata as $segment){
foreach($segment as $key => $value ){
$newArray[$value] = $value;
}
}
my array looks like:
Array ( [UNIQUE] => UNIQUE
[buuu] => buuu
[NICKNAME] => NICKNAME
[NoAd] => NoAd )
i tried use 3x foreach but it ends in error all time i think i need to change some variables in my foreach but no idea how.
Now that I see the other answers it seems it's array_column you are looking for.
It returns an array column and the third parameter is what the key name should be.
$player_data = array(array(
"ID" => 1,
"USER_ID" => 1,
"DATA" => "UNIQUE",
"VALUE" => "buuu"
),
array(
"ID" => 1,
"USER_ID" => 1,
"DATA" => "NICKNAME",
"VALUE" => "NoAd"
));
$new = array_column($player_data, "VALUE", "DATA");
var_dump($new);
Output:
array(2) {
["UNIQUE"]=>
string(4) "buuu"
["NICKNAME"]=>
string(4) "NoAd"
}

There is no need for loops to solve this.
lets assume $playerdata has the below values
Array (
[0] => Array (
[ID] => 1
[USER_ID] => 1
[DATA] => UNIQUE
[VALUE] => buuu )
[1] => Array (
[ID] => 2
[USER_ID] => 1
[DATA] => NICKNAME
[VALUE] => NoAd ) )
[2]----
[3]----
$newArray = [];
foreach($playerdata as $record) {
$newArray[$record['DATA']] = $record['DATA'];
$newArray[$record['VALUE']] = $record['VALUE'];
}
print_r($newArray);
You could try something like the following:
$newArray = array();
foreach($playerdata as $segment){
$newArray[$segment['DATA']] = $segment['VALUE'];
}
This code gets the DATA as key and VALUE as value from each part of the array and stores it in $newArray.
How to add extra values to a existing array
$item = get_post_meta($post->ID, 'extra_fileds', true);
when I print $item I get the following
Array
(
[0] => Array ( [name] => test1 [type] => this1 [location] => 1 )
[1] => Array ( [name] => test2 [type] => this2 [location] => 2 )
)
I would like to add a extra field and make it like`
Array
(
[0] => Array ( [name] => test1 [type] => this1 [location] => 1 )
[1] => Array ( [name] => test2 [type] => this2 [location] => 2 )
[2] => Array ( [name] => test3 [type] => this3 [location] => 3 )
)
Thank you in advance
Write
$item[] = ['name'=>'test3','type'=>'this3','location'=>3];
Here either you can use array_push or $rows[] will solve your problem.
Try this code snippet here
ini_set('display_errors', 1);
$rows=Array (
0 => Array ( "name" => "test1","type" => "this1", "location" => 1 ),
1 => Array ( "name" => "test2" ,"type" => "this2", "location" => 2 ) );
$arrayToAdd=Array ( "name" => "test3","type" => "this3", "location" => 3 );
Solution 1:
array_push($rows, $arrayToAdd);
Solution 2:
$rows[]=$arrayToAdd;
Use array push.
$new_array_item=array("name" => "test3","type" => "this3", "location" => 3);
array_push($item, $new_array_item);
print_r($item);
You're array is at the moment stored in $item.
To add a new item use these brackets: [ ].
Here is your code:
$item[] = [
'name' => 'test3'
'type' => 'this3'
'location' => 3
]
You can use this as much as you like to add more items.
I think that this is the best solution but you can also take a look at php array_push() function.
I am trying to form a specific multidimensional array from a mysql result set.
I would like it to look like this:
array(
'product_name' => 'prod_1',
'categories' => array(1,2,3,4)
);
The db result return an array that looks something like this
Array
(
[0] => Array
(
[id] => 1
[product_name] => prod_1
)
[1] => Array
(
[id] => 2
[product_name] => prod_1
)
[2] => Array
(
[id] => 3
[product_name] => prod_1
)
[3] => Array
(
[id] => 4
[product_name] => prod_1
)
As you can see, i would like to group the product name and place the id into another array
Does anyone have any tips on how to do this?
$yourarray = array(array('id'=>1, 'product_name' => 'prod_1'), array('id'=>2, 'product_name' => 'prod_2'),array('id'=>3, 'product_name' => 'prod_3'));
$multiarray = array();
for($i=0; $i<count($yourarray);$i++){
$multiarray['product_name'][] = $yourarray[$i]['product_name'];
$multiarray['product_id'][] = $yourarray[$i]['id'];
}
print_r($yourarray); //original array
print_r($multiarray); //gives you multi array
Something similar to this?
Your original array:
Array
(
[0] => Array
(
[id] => 1
[product_name] => prod_1
)
[1] => Array
(
[id] => 2
[product_name] => prod_2
)
[2] => Array
(
[id] => 3
[product_name] => prod_3
)
)
The result would print:
Array
(
[product_name] => Array
(
[0] => prod_1
[1] => prod_2
[2] => prod_3
)
[product_id] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
Did you try GROUP_CONCAT. It's something like:
SELECT name, GROUP_CONCAT(name) AS friends FROM friendships GROUP BY name;

$multiarray = array();
foreach ($yourarray as $value) {
if(!isset($multiarray['product_name'])) {

The difficulty here is that PHP's functions such as array_merge() and array_merge_recursive() will not merge data into numeric keys, but rather will re-key any duplicate numeric key. So for example given two arrays:
array(
'test' => 'abc',
0 => 'xyz'
);
array(
'test' => 'def',
0 => 'uvw'
);
Merging them together with array_merge() will produce an array like:
array(
'test' => 'def',
0 => 'xyz',
1 => 'uvw'
);
So, you need a custom function to be "additive" on any key, regardless of whether it is a string or numeric key. Try this:
function mixed_key_array_merge() {
$args = func_get_args();
$result = array();
foreach ($args as $arg) {
// discard non-array arguments; maybe this could be better handled
if (!is_array($arg)) {
continue;
}
foreach ($arg as $key => $value) {
if (!isset($result[$key])) {
$result[$key] = $value;
} else if (is_array($result[$key])) {
$result[$key] = call_user_func_array('mixed_key_array_merge',array($result[$key],$value));
}
}
}
return $result;
}
