How can I do to merge "artist" value with "title" value in one value?. I'm using PHP 5.2.4 if that helps.
I have this array
Array
(
[0] => Array
(
[artist] => Narcosis
[title] => Destruir
[duration] => 137
[date] => 1370807642
[genre_id] => 18
)
[1] => Array
(
[artist] => Ricardo Palma Fanjul
[title] => Mutant
[duration] => 347
[date] => 1448227909
[genre_id] => 18
)
)
The expected output would be like this, just show element "title" with twice values:
Array
(
[0] => Array
(
[title] => Narcosis - Destruir
[duration] => 137
[date] => 1370807642
[genre_id] => 18
)
[1] => Array
(
[title] => Ricardo Palma Fanjul - Mutant
[duration] => 347
[date] => 1448227909
[genre_id] => 18
)
)
Try this:
foreach ($mainArr as $index=>$subArr) {
$subArr['title'] = $subArr['artist'].' - '.$subArr['title'];
unset($subArr['artist']);
$mainArr[$index] = $subArr;
}
mainArr is the array declared above.
p.s. I have not tested this code yet
Try this:
$new = array_map(function($v) {
$v['title'] = $v['artist'].' - '.$v['title'];
unset($v['artist']);
return $v;
}, $arr);
OR
foreach ($arr as &$a) {
$a['title'] = $a['artist'].' - '.$a['title'];
unset($a['artist']);
}

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 stuck on this and really don't know how to solve it.
I have two multi-dimensional arrays and need to match every "entry_id" from second array with first one. Then need to check if every "file_no" from second array is in database (first array) and "status" are matched with 1st array . If "status" is different, update second array with string (e.g. updated value) like this:
...
[status] => Array
(
[0] => abc
[1] => defghijk - "updated value"
)
So I have first array from database:
Array
(
[0] => Array
(
[entry_id] => 1
[file_no] => KSBR 40 INS 3674 / 2014
[status] => abc
)
[1] => Array
(
[entry_id] => 9
[file_no] => KSUL 77 INS 18898 / 2013
[status] => abc
)
[2] => Array
(
[entry_id] => 9
[file_no] => KSUL 77 INS 21218 / 2013
[status] => defg
)
)
And second array generated from script:
Array
(
[0] => Array
(
[entry_id] => 1
[id] => 500910/098
[fullname] => Milan Vrtal
[type] => person
[file_no] => Array
(
[0] => KSBR 26 INS 37146 / 2013
[1] => KSBR 40 INS 3674 / 2014
)
[status] => Array
(
[0] => status1
[1] => status2
)
)
[1] => Array
(
[entry_id] => 2
[id] => 46900217
[fullname] => ENTEC a.s.
[type] => company
[file_no] => Array
(
[0] => KSBR 28 INS 1232 / 2013
)
[status] => Array
(
[0] => qwer
)
)
[2] => Array
(
[entry_id] => 9
[fullname] => Blanka Kořínková
[type] => person
[file_no] => Array
(
[0] => KSUL 77 INS 18898 / 2013
[1] => KSUL 77 INS 21218 / 2013
)
[status] => Array
(
[0] => abc
[1] => defghijk
)
)
)
Thanks for every comment and sorry for english :)
This is by creating a temporary array to search in. This will use quite some memory when the arrays are big, but will result in faster execution time...
$tmparr = array();
foreach($arr1 as $arr1_val)
{
//put an new element in $temparr with key 'entry_id' and an array as value
if (!isset($tmparr[$arr1_val['entry_id']]))
$tmparr[$arr1_val['entry_id']] = array();
//add the status to the array
$tmparr[$arr1_val['entry_id']][] = $arr1_val['status'];
}
/*
$tmparr = Array
(
[1] => Array
(
[0] => abc
)
[9] => Array
(
[0] => abc
[1] => defg
)
)
*/
//arr2_val by reference so that we can change it
foreach($arr2 as &$arr2_val)
{
//get the current entry_id
$entry_id = $arr2_val['entry_id'];
//see if this entry_id was in the first array, and if so...
if (isset($tmparr[$entry_id]))
{
//change the status to both the original status and the status of the first array
$arr2_val['status'] = array_merge($arr2_val['status'],$tmparr[$entry_id]);
}
}
print_r($arr2);
Output:
Array
(
[0] => Array
(
[entry_id] => 1
[id] => 500910/098
[fullname] => Milan Vrtal
[type] => person
[file_no] => Array
(
[0] => KSBR 26 INS 37146 / 2013
[1] => KSBR 40 INS 3674 / 2014
)
[status] => Array
(
[0] => status1
[1] => status2
[2] => abc
)
)
[1] => Array
(
[entry_id] => 2
[id] => 46900217
[fullname] => ENTEC a.s.
[type] => company
[file_no] => Array
(
[0] => KSBR 28 INS 1232 / 2013
)
[status] => Array
(
[0] => qwer
)
)
[2] => Array
(
[entry_id] => 9
[fullname] => Blanka Kořínková
[type] => person
[file_no] => Array
(
[0] => KSUL 77 INS 18898 / 2013
[1] => KSUL 77 INS 21218 / 2013
)
[status] => Array
(
[0] => abc
[1] => defghijk
[2] => abc
[3] => defg
)
)
)
edit: This is possible too, whitout the temp array, but with a loop in a loop. This will be slower than the first one, but will consume less memory:
//arr2_val by reference so that we can change it
foreach($arr2 as &$arr2_val)
{
//get the current entry_id
$entry_id = $arr2_val['entry_id'];
//search for the correct row in the first array
foreach($arr1 as $arr1_val)
{
if ($arr1_val['entry_id'] == $arr2_val['entry_id'])
{
$arr2_val['status'][] = $arr1_val['status'];
//a continue should be added here to make it faster...
}
}
}
print_r($arr2);
This should work
foreach($array1 as $i)
{
foreach($array2 as $key=>$j)
{
if($j['entry_id'] == $i['entry_id'])
{
if($array2[$key]['status'] != $i['status'])
{
$j['status'] = array(
$i['status'],
$j['status'] // the new status
);
}
continue;
}
}
}
I found a solution for you :
$a1 = [['entry_id' => 1, 'file_no' => 'KSBR', 'status' => 'abc'], ['entry_id' => 2, 'file_no' => 'KSUL', 'status' => 'defg']];
$a2 = [['entry_id' => 1, 'file_no' => 'KSBR', 'status' => 'abc', 'type' => 'person'], ['entry_id' => 2, 'file_no' => 'KSUL', 'status' => 'defg']];
print_r(new_array_merge_recursive($a1, $a2));
function new_array_merge_recursive(array $array1, array $array2=array())
{
$arrays = func_get_args();
$merge = array_shift($arrays);
foreach ($arrays as $array)
{
foreach ($array as $key => $val)
{
if (is_array($val) && array_key_exists($key, $merge))
{
$val = new_array_merge_recursive((array) $merge[$key], $val);
}
$merge[$key] = $val;
}
}
return $merge;
}
I want to merge two arrays into one array as follows,
Array1:
Array
(
[0] => Array
(
[id] => 3
[sku] => KOG456
[cart_id] => 2
[name] => Young Money
[slug] => young-money
[route_id] => 47
[description] =>
This is test song
[excerpt] =>
[saleprice] => 90.00
[related_products] =>
[images] => {"1c6b0883fc94c5f644497ec488cdf8cb":{"filename":"1c6b0883fc94c5f644497ec488cdf8cb.jpg","alt":"Test","caption":"","primary":true}}
[seo_title] =>
[meta] =>
[enabled] => 1
)
)
Array2:
Array
(
[0] => Array
(
[filename] => Beethovens_Symphony_No._9_(Scherzo).wma
[title] => Young Money
[size] => 599.26
)
)
Expected array result is:
Array
(
[0] => Array
(
[id] => 3
[sku] => KOG456
[cart_id] => 2
[name] => Young Money
[slug] => young-money
[route_id] => 47

How to merge these array elements into one array element ?
foreach ($origArray as $key => &$subArray)
$subArray += $arrayToBeAdded[$key];
Where $origArray is your array which is to be merged into and $arrayToBeAdded the array you merge into.
User array_merge_recursive():
$final = array_merge_recursive($array1, $array2);
Try this little known overload of the + operator for arrays:
$result = $array1[0] + $array2[0]
Use function array_merge($array1[0], $array2[0]) . Following is the example for the same
$array1 = array(0=>array('1'=>1,'2'=>2,'3'=>3));
$array2 = array(0=>array('4'=>4,'5'=>5,'6'=>6));
$result[0] = array_merge($array1[0],$array2[0]);
echo '<pre>';
print_r($result);
Since you have unique keys, you could use something as simple as the + operator (union)...
For example:
$arr1 = [1=>'testing',2=>'stack',3=>'overflow'];
$arr2 = [4=>'something',5=>'else',6=>'here'];
$arr3 = $arr1 + $arr2;
print_r($arr3);
Results:
Array ( [1] => testing [2] => stack [3] => overflow [4] => something [5] => else [6] => here )
For this php has multiple functions. You can use $arrays = array_combine($array1, $array2);.
PHP.net - array_combine
Hope it helped!
I have merge two array with php function "merge_recursive" (both came from sql query) all of them have a common field [date] is it possible to sort array[new] by [date] field ?
[new] => Array

I want that aray will be sort like (example below)
[1] = Array
(
)
[0] = Array
(
)
[2] = Array
(
)
is it possible?
You can use array_multisort, which does exactly what you want.
$dates = array();
foreach ($new as $key => $value) { // $new is your array
$dates[$key] = $value['date'];
}
array_multisort($dates, SORT_ASC, $new);
This is easily extendible with multiple sort criteria.
You could try something like this:
http://us3.php.net/manual/en/function.uasort.php
function compareDate($a, $b) {
if ($a["date"] == $b["date"]) {
return 0;
}
return ($a["date"] < $b["date"]) ? -1 : 1;
}
uasort($input, compareDate);
and i got a problem (its big for me) :(
ok, i have some array like ...
Array(
[0] => Array
(
[id] => 1
[order_sn] => EU/2011/04/PO/5
[total] => 65
)
[1] => Array
(
[id] => 1
[order_sn] => EU/2011/04/RS/4
[total] => 230
)
[2] => Array
(
[id] => 1
[order_sn] => EU/2011/04/RS/3
[total] => 130
)
[3] => Array
(
[id] => 2
[order_sn] => EU/2011/04/RS/2
[total] => 100
)
[4] => Array
(
[id] => 2
[order_sn] => EU/2011/04/RS/1
[total] => 60
)
)
how to merge them if the array have same key value ... ?
the result that i need got is like this ...
Array(
[0] => Array
(
[id] => 1
[detail] => Array
(
[0] => Array
(
[order_sn] => EU/2011/04/PO/5
[total] => 65
)
[1] => Array
(
[order_sn] => EU/2011/04/RS/4
[total] => 230
)
[2] => Array
(
[order_sn] => EU/2011/04/RS/3
[total] => 130
)
)
)
[2] => Array
(
[id] => 2
[detail] => Array
(
[0] => Array
(
[order_sn] => EU/2011/04/RS/2
[total] => 100
)
[1] => Array
(
[order_sn] => EU/2011/04/RS/1
[total] => 60
)
)
)
)
im very need some help here, and im working on PHP ... what method should i do for this case?
i try too searching on google and in here ... but i dont know the keyword >.<
Many thanks before :)
regard, Stecy
Try like this:
<?php
$result = array();
foreach ($my_array as $v) {
$id = $v['id'];
$result[$id]['id'] = $id;
$result[$id]['detail'][] = array(
'order_sn' => $v['order_sn'],
'total' => $v['total'],
);
}
You can just loop over the array and build a resulting one:
// $a is your array
$r=array();
foreach($a as $v)
$r[$v['id']][]=array('order_sn'=>$v['order_sn'], 'total'=>$v['total']);
echo'<pre>';
var_dump($r);
Since you do the paring by ID, it is wise to have it as the key and all the data associated with it as the value. There's no need to also have id and detail.
foreach($origianlArray as $key => $value){
$newArray[$value['id']]['id'] = $value['id'];
$newArray[$value['id']]['detail'][] = array('order_sn' => $value['order_sn'], 'total' => $value['total']);
}
Check out the PHP array_merge function.
