I have array with data:
$data = [
Array (
[0] => Array ( [lcd] => 14, [cpu] => Intel, [vga] => Nvidia )
[1] => Array ( [lcd] => 14, [cpu] => AMD, [vga] => Nvidia )
[2] => Array ( [lcd] => 15, [cpu] => Intel, [vga] => Integrated )
[3] => Array ( [lcd] => 15, [cpu] => AMD, [vga] => AMD )
[4] => Array ( [lcd] => 16, [cpu] => Intel, [vga] => Іntegrated )
[5] => Array ( [lcd] => 16, [cpu] => AMD, [vga] => Nvidia )
);
AND user form:
<form>
<p>LCD</p>
<input name="lcd[]" value="14">
<input name="lcd[]" value="15">
<input name="lcd[]" value="16">
<p>CPU</p>
<input name="cpu[]" value="Intel">
<input name="cpu[]" value="AMD">
<p>VGA</p>
<input name="vga[]" value="Nvidia">
<input name="vga[]" value="AMD">
<input name="vga[]" value="Integrated">
</form>
User pick some inputs and I need to get keys from $data array:
For example user click lcd = 14, lcd = 15 and cpu = Intel
I get array from user:
Array ( [lcd] => Array ( [0] => 14 [1] => 15 ) [cpu] => Array ( [0] => Intel ) )
I need keys from $data array where lcd = 14 OR 15 AND cpu = Intel
It should be dynamically changed depending on which value the user chooses.
I can get data when I know values:
$result = array_filter($data, function($data) {
return $data['cpu'] == 'Intel' && in_array($data['lcd'], ['14', '15']);
});
But I can't do this with user values.

I would like to order $ArrayToOrder according to column SecondArrayField2 in $SecondArray, where the link between the two arrays are Field_3 (in $ArrayToOrder) and SecondArrayField1 in $SecondArray.
$ArrayToOrder=Array
(
[0] => Array
(
[Field_1] => 13
[Field_2] => 15
[Field_3] => 3
)
[1] => Array
(
[Field_1] => 25
[Field_2] => 17
[Field_3] => 2
)
[2] => Array
(
[Field_1] => 121
[Field_2] => 20
[Field_3] => 11
)
)
$SecondArray=Array
(
[0] => Array
(
[SecondArrayField1] => 11
[SecondArrayField2] => Bruce
)
[1] => Array
(
[SecondArrayField1] => 3
[SecondArrayField2] => Arthur
)
[2] => Array
(
[SecondArrayField1] => 2
[SecondArrayField2] => Mary
)
)
Desired result as follows:
$ArrayToOrder=Array
(
[0] => Array
(
[Field_1] => 13
[Field_2] => 15
[Field_3] => 3 //(Arthur)
)
[1] => Array
(
[Field_1] => 121
[Field_2] => 20
[Field_3] => 11 //(Bruce)
)
[2] => Array
(
[Field_1] => 25
[Field_2] => 17
[Field_3] => 2 //(Mary)
)
)
Here is snippet you can use,
// first fetching key as SecondArrayField2 and SecondArrayField1 as value
$Field_3 = array_column($SecondArray, "SecondArrayField1","SecondArrayField2");
// sort by key alphabetically
ksort($Field_3);
//
$sorted = array_values(array_map(function($v) use ($ArrayToOrder) {
// first fetched Field_3 matching with current value of $Field_3 in the order
// get the index of matching Field_3
// save it to sorted array its sub array
return $ArrayToOrder[array_search($v, array_column($ArrayToOrder,'Field_3'))];
}, $Field_3));
print_r($sorted);die;
Demo.
Output:
Array
(
[0] => Array
(
[Field_1] => 13
[Field_2] => 15
[Field_3] => 3 //(Arthur)
)
[1] => Array
(
[Field_1] => 121
[Field_2] => 20
[Field_3] => 11 // (Bruce)
)
[2] => Array
(
[Field_1] => 25
[Field_2] => 17
[Field_3] => 2 // (Mary)
)
)

I have a PHP array like the following one and I would like to combine a multi array to one array:
Array
(
[0] => ADB_DW2017
[1] => LM9
[2] => MS_OF2013
)
Array
(
[0] => NK
[1] => PV
[2] => NK
)
Array
(
[0] => 15
[1] => 25
[2] => 10
)
Array
(
[0] => 250
[1] => 111
[2] => 150
)
Array
(
[0] => 450
[1] => 123
[2] => 250
)
Array
(
[0] => 0
[1] => Mien thue
[2] => 5
)
Array
(
[0] => 200
[1] => 12
[2] => 100
)
Array
(
[0] => 6.750
[1] => 3.075
[2] => 2.500
)
I want to combine like this, with the highest performance :
Array
(
[ADB_DW2017]=>array([suppiler]=>NK
[min_pro]=>15
[max_pro]=>250
[avg_pro]=>450
[tax]=>0
[com]=>200
[sum]=>6.750
)
)
My question is : How to combine a multi array to one array in PHP with the highest performance ?
I assume array names are $first_array,$second_array,...... (so change varabile names accordingly).
Do like below:-
$final_array = array();
foreach ($first_array as $key=> $arr){
$final_array[$arr] =array(
'suppiler'=>(isset($second_array[$key]))? $second_array[$key]: '',
'min_pro'=>(isset($third_array[$key]))? $third_array[$key]: 0,
'max_pro'=>(isset($fourth_array[$key]))? $fourth_array[$key]: 0,
'avg_pro'=>(isset($fifth_array[$key]))? $fifth_array[$key]: 0,
'tax'=>(isset($sixth_array[$key]))? $sixth_array[$key]: '',
'com'=>(isset($seventh_array[$key]))? $seventh_array[$key]: 0,
'sum'=>(isset($eigth_array[$key]))? $eigth_array[$key]: 0
);
}
echo "<pre/>";print_r($final_array);

Our Result:
Array (
[0] => Array ( [0] => Province [1] => Party [2] => Age [3] => Name [4] => Gender )
[1] => Array ( [0] => Quebec [1] => NDP [2] => 22 [3] => Liu, Laurin [4] => Female )
[2] => Array ( [0] => Quebec [1] => Bloc Quebecois [2] => 22 [3] => Mourani, Maria [4] => Female )
)
I want a result looking like this: How to convert like this?
array(
['Province'=>'Quebec','Party'=>'NDP','Age'=>22,'Name'=>'Liu, Laurin','Gender'=>'Female'],
['Province'=>'Quebec','Party'=>'Bloc Quebecois','Age'=>43,'Name'=>'Mourani, Maria','Gender'=>'Female']
)
OR
array(
['Province', 'Party', 'Age', 'Name', 'Gender'],
['Quebec', 'NDP', 22, 'Liu, Laurin', 'Female'],
['Quebec', 'Bloc Quebecois', 43, 'Mourani, Maria', 'Female']
)
Pretty simple using an array_combine() to set the headers for each row, and just walking the array setting those headers:
$headers = array_shift($myArray);
array_walk(
$myArray,
function(&$row) use ($headers) {
$row = array_combine($headers, $row);
}
);

how to create new array become

[Personal Impact] => Array
(
[Position] => array
(
[0] => array
(
[question_summary] =>
[answer1] => 18
[answer2] => 3

[driver_name] => Position
[cluster_name] => Personal Impact
)
)
)
)
Is it possible?
Yes it's possible you can just foreach(your values as key => value) {} it or something like this:
Sample Fiddle
<?php
$new_values = array();
foreach($old_values as $key => $values) {
$new_values[$values['cluster_name']][$values['driver_display_name']][] = array(
'answer1' => $values['answer1'],
'answer2' => $values['answer2'],
'PercentEVQ' => $values['PercentEVQ'],
'PercentEVQ2' => $values['PercentEVQ2'],
'driver_display_name' => $values['driver_display_name'],
'cluster_name' => $values['cluster_name'],
);
}
Are you defining a new array?
$new_array['Personal Impact']['Position'] = $old_array;

You can use array_combine()
Creates an array by using the values from the keys array as keys and
the values from the values array as the corresponding values.
You can use array_combine()
Sample code for you.
<?PHP
$array_a = array
(
0 => 224,
1 => 77,
2 => 78,
3 => 79,
4 => 80,
5 => 81,
6 => 82,
7 => 76
);
$array_b = array
(
0 => "Men Shoes",
1 => "Fashion Accessories",
2 => "Men Apparels",
3 => "Shoes & Belts",
4 => "Watches & Clocks",
5 => "Women Apparels",
6 => "Others",
7 => "Bags"
);
$new_array = array_combine($array_a,$array_b);
print_r($new_array);
?>
