I have this array:
Array
(
[0] => Array
(
[id] => 1
[name] => Something
[other_id] => 2
[other_name] => One
)
[1] => Array
(
[id] => 1
[name] => Something
[other_id] => 3
[other_name] => Two
)
[2] => Array
(
[id] => 1
[name] => Something
[other_id] => 3
[other_name] => Three
)
[3] => Array
(
[id] => 1
[name] => Something
[other_id] => 2
[other_name] => Four
)
)
Now I need the array to look like this:
Array
(
[0] => Array
(
[id] => 1
[name] => Something
[0] => Array
(
[other_id] => 2
[other_name] => One
)
[1] => Array
(
[other_id] => 3
[other_name] => Two
)
[2] => Array
(
[other_id] => 4
[other_name] => Three
)
)
)
I tried different ways but no result. I hope someone can help me a little bit with that.
Not sure I understand what you want, but this might do it:
//Somewhere to store the result.
$output = array();
//Loop through the input array.
foreach($input as $element) {
$id = $element['id'];
$other_id = $element['other_id'];
if(!isset($output[$id])) {
//ID is not already in the output array, so add it.
$output[$id] = array(
'id' => $id,
'name' => $element['name'],
);
}
if(!isset($output[$id][$other_id])) {
//Other_ID is not already in the output array, so add it.
$output[$id][$other_id] = array(
'other_id' => $other_id,
'other_name' => $element['other_name'],
);
}
}

I've merged two arrays. A duplicate entry is a deleted. Let me explain the as an example (I have compare array using user_id)
$array1 = Array
(
[0] => Array
(
[id] => 44
[user_id] => 2
[name] => jina_testl
[profilePhoto] =>
)
)
$array2 = Array
(
[0] => Array
(
[id] => 2
[user_id] => 3
[name] => demo_test1
[profilePhoto] =>
)
[1] => Array
(
[id] => 3
[user_id] => 2
[name] => abc
[profilePhoto] =>
)
[2] => Array
(
[id] => 4
[user_id] => 4
[name] => test
[profilePhoto] =>
)
)
I have merged array1 and array2 and duplicate array remove. I get the following output:
Array
(
[0] => Array
(
[id] => 44
[user_id] => 2
[name] => jina_testl
[profilePhoto] =>
)
[1] => Array
(
[id] => 2
[user_id] => 3
[name] => demo_test1
[profilePhoto] =>
)
[3] => Array
(
[id] => 4
[user_id] => 4
[name] => abc
[profilePhoto] =>
))
But I want such an output like this:
Array
(
[0] => Array
(
[id] => 2
[user_id] => 3
[name] => demo_test1
[profilePhoto] =>
)
[1] => Array
(
[id] => 4
[user_id] => 4
[name] => abc
[profilePhoto] =>
))
You could do something like the following: first get all the user_ids that we do not want to be included, by taking the intersection of the two columns.
If we then merge the two separate arrays and exclude the ones that are present in the array of unwanted IDs we should get our final result.
$userId = 'user_id';
$userIdsArray1 = array_column($array1, $userId);
$userIdsArray2 = array_column($array2, $userId);
// If we then take the negation we should get something similar to an exclusive or.
// Thus those in one or the other but not in both arrays.
$unwantedUserIds = array_intersect($userIdsArray1, $userIdsArray2);
$result = [];
foreach (array_merge($array1, $array2) as $record) {
if (!in_array($record[$userId], $unwantedUserIds)) {
$result[] = $record;
}
}
echo '<pre>', print_r($result, true), '</pre>';
Result:
Array
(
[0] => Array
(
[id] => 2
[user_id] => 3
[name] => demo_test1
[profilePhoto] =>
)
[1] => Array
(
[id] => 4
[user_id] => 4
[name] => test
[profilePhoto] =>
)
)
Assuming I have an array and recursively want to do some task. I have spent one day for this unable to solve this. May be my logic is not good.
Any help on how to do such thing in an efficient way would save my days.
I have an array with n level deep, looking like:
Array
(
[0] => Array
(
[name] => user1
[email] => user1#demo.com
[depth] => 1
)
[1] => Array
(
[name] => user2
[email] => user2#demo.com
[depth] => 1
[0] => Array
(
[0] => Array
(
[name] => user2.1
[email] => user2.1#demo.com
[depth] => 2
)
)
)
[2] => Array
(
[name] => user3
[email] => user3#demo.com
[depth] => 1
[0] => Array
(
[0] => Array
(
[name] => user3.1
[email] => user3.1#demo.com
[depth] => 2
[0] => Array
(
[0] => Array
(
[name] => user3.1.1
[email] => user3.1.1#demo.com
[depth] => 3
)
)
)
[1] => Array
(
[name] => user3.2
[email] => user3.2#demo.com
[depth] => 2
)
)
)
)
I want to change above array in exactly this format:
array(
0 => array(
'name' => 'user1',
),
1 => array(
'name' => 'user2',
'children' => array(
0 => array(
'name' => 'user2.1',
) ,
) ,
) ,
2 => array(
'name' => 'user3',
'children' => array(
0 => array(
'name' => 'user3.1',
'children' => array(
0 => array(
'name' => 'user3.1.1',
) ,
) ,
) ,
1 => array(
'name' => '3.2',
)
) ,
) ,
)
Edited:
I am using this code and working fine if i want to show data in tree format but unable to push data into array as i want.
function displayArrayRecursively($arr, $indent='') {
if ($arr) {
foreach ($arr as $key => $value) {
if (is_array($value)) {
displayArrayRecursively($value, $indent . '-->');
} else {
if ($key == 'name')
{
echo "$indent $value <br>";
}
else {
continue;
}
}
}
}
}
displayArrayRecursively($userListArray);
Can anyone suggest me how to do this?
Thank you
This function will do what you want:
function process_nodes($nodes) {
$new = array();
foreach ($nodes as $node) {
$new[] = array('name' => $node['name']);
if (isset($node[0])) {
$new[count($new)-1]['children'] = process_nodes($node[0]);
}
}
return $new;
}
print_r(process_nodes($data));
Output:
Array
(
[0] => Array
(
[name] => user1
)
[1] => Array
(
[name] => user2
[children] => Array
(
[0] => Array
(
[name] => user2.1
)
)
)
[2] => Array
(
[name] => user3
[children] => Array
(
[0] => Array
(
[name] => user3.1
[children] => Array
(
[0] => Array
(
[name] => user3.1.1
)
)
)
[1] => Array
(
[name] => user3.2
)
)
)
)
I tries to array_merge in php but resultant array is not correct
1. Array ( [id] => 12 [name] => Popular )
2. Array ( [0] => Array ( [id] => 8 [name] => Flowers ) [1] => Array ( [id] => 10 [name] => Chocolates ) [2] => Array ( [id] => 11 [name] => Sweets and Dry Fruits ) )
Resultant Array
Array ( [id] => 12 [name] => Popular [0] => Array ( [id] => 8 [name] => Flowers ) [1] => Array ( [id] => 10 [name] => Chocolates ) [2] => Array ( [id] => 11 [name] => Sweets and Dry Fruits ) )
If you just want to add the new data in the same format as the existing data then use [] rather than array_merge().
$array1 = array( 'id' => 12, 'name' => 'Popular');
$array2 = array(array( 'id' => 8, 'name' => 'Flowers'),
array( 'id' => 10, 'name' => 'Chocolates'),
array( 'id' => 11, 'name' => 'Sweets and Dry Fruits')
);
$array2[] = $array1;
print_r($array2);
outputs...
Array
(
[0] => Array
(
[id] => 8
[name] => Flowers
)
[1] => Array
(
[id] => 10
[name] => Chocolates
)
[2] => Array
(
[id] => 11
[name] => Sweets and Dry Fruits
)
[3] => Array
(
[id] => 12
[name] => Popular
)
)
If you want the data to be at the front, then you need to create an array of that data and then use array_merge()...
$array3 = array_merge(array($array1), $array2);
print_r( $array3);
I have one array in two format. I want to change array from
Array
(
[step_number] => 4
[app_id] => Array

[1] => 3
)
[formdata] => Array
(
[0] => Array
(
[name] => app_id[]
[value] => 2
)
[1] => Array
(
[name] => app_id[]
[value] => 3
)
[2] => Array

[value] => 200
)
[4] => Array
(

[value] => new plan
)
[6] => Array

)
[8] => Array
(
[name] => price
[value] =>
)
[9] => Array
(
[name] => sell_type
[value] => us
)
)
)
this format to
Array
(
[app_id] => Array
(
[0] => 2
[1] => 3
)
[fieldval] => Array
(
[2] => Array
(
[2] => Array

[1] => day
)
)
)
[title] => new plan
[feature_plan] => 3
[plan_type] => free
[price] =>
[sell_type] => us
)
these are are one array into two format. i have data in to first array format and i want to change that format to second array type format.
please tell me how i am trying this for 2 days but not succeed.
Here is a function you could use to produce that conversion:
function convert_formdata($input) {
$output = array();
foreach($input['formdata'] as $data) {
$keys = preg_split("#[\[\]]+#", $data['name']);
$value = $data['value'];
$target = &$output;
foreach($keys as $key) {
// Get index for "[]" reference
if ($key == '') $key = count($target);
// Create the key in the parent array if not there yet
if (!isset($target[$key])) $target[$key] = array();
// Move pointer one level down the hierarchy
$target = &$target[$key];
}
// Write the value at the pointer location
$target = $value;
}
return $output;
}
You would call it like this:
$output = convert_formdata($input);
See it run on eval.in for the given input. The output is:
array (
'app_id' =>
array (
0 => 2,
1 => 3,
),
'fieldval' =>
array (
2 =>
array (
2 =>
array (
0 => 1,
),
),
3 =>
array (
3 =>
array (
0 => 200,
1 => 'day',
),
),
),
'title' => 'new plan,',
'feature_plan' => 3,
'plan_type' => 'free',
'price' => NULL,
'sell_type' => 'us',
)
I have a multidimensional Array like this:
Array (
[0] => Array (
[id] => 1
[name] => privilages1
)
[1] => Array (
[id] => 2
[name] => privilages2
)
[2] => Array (
[id] => 3
[name] => privilages3
)
[3] => Array (
[id] => 4
[name] => privilage4 )
[4] => Array (
[id] => 5
[name] => privilages5 )
)
and i want to compare it with another array, which looks like this:
Array (
[0] => Array (
[id] => 1 )
[1] => Array (
[id] => 2)
)
if the value of id matches, then i want to all values from the first example.
How can i do this?
You can use array_filter to filter the array elements you want by supplying a user defined callback function.
Here is the code:
$arr = array( array('id' => 1, 'name' => 'foo'),
array('id' => 2, 'name' => 'bar'),
array('id' => 3, 'name' => 'baz'),
array('id' => 4, 'name' => 'wow'));
$ret = array_filter($arr, create_function('$el',
'static $search=array(array("id" => 1), array("id" => 2));
$n=array("id" => $el["id"]);
return (array_search($n, $search) !== false);'));
print_r($ret);
OUTPUT
Array
(
[0] => Array
(
[id] => 1
[name] => foo
)
[1] => Array
(
[id] => 2
[name] => bar
)
)
