convert multidimensional array to single dimension.
I have a multidimensional array like this..PHP using array finctions
Array
(
[0] => Array
(
[0] => Name1
[1] => valueOfName1
)
[0] => Array
(
[0] => Name2
[1] => valueOfName2
)
[2] => Array
(
[0] => Name3
[1] => valueOfName3
)
[3] => Array
(
[0] =>
)
[4] => Array
(
[0] => Name4
[1] => valueOfName4
)
[5] => Array
(
[0] =>
)
);
i want output like this..unsing any of function fo array
Array
(
Name1 => valueOfName1
Name2 => valueOfName2
Name3 => valueOfName3
Name4 => valueOfName4
)
Try this code:
$newArr = array();
foreach($mainArr as $key=>$value) {
if(isset($value[0]) && $value[0]!= '' && isset($value[1]) && $value[1] != '') {
$newArr[$value[0]] = $value[1];
}
}
print_r($newArr);
its simple... first try something befor you post a question...
$people = array (
"1" => array (
"0" => "greenspan",
"1" => 32
),
"2" => array (
"0" => "doe",
"1" => 52
)
);
$new_people = array();
while(list($person, $person_array) = each($people))
{
while(list($person_attribute, $value) = each($person_array))
{
$new_people[$person_attribute] = $value;
}
}
print_r($new_people);
Try out This Example:
<?php // Array representing a possible record set returned from a database
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe',
) );
$last_names = array_column($records, 'last_name', 'id');
print_r($last_names); ?>
Output :
Array (
[2135] => Doe
[3245] => Smith
[5342] => Jones
[5623] => Doe )
Hope this might be useful to you !!!

I want to expand my city array with post code value.
If the city_postcode array contain city array name record then push postcode value into city array. That's what i want to achive somehow.
city array:
Array
(
[0] => Array
(
[id] => 1
[city] => Budapest
[population] => 1700000
)
[1] => Array
(
[id] => 2
[city] => Szeged
[population] => 160000
)
)
city_postcode array:
Array
(
[0] => Array
(
[name] => Budapest
[post_code] => 12345
)
[1] => Array
(
[name] => Szeged
[post_code] => 33356
)
)
The result I want:
Array
(
[0] => Array
(
[id] => 1
[city] => Budapest
[population] => 1700000
[post_code] => 12345
)
[1] => Array
(
[id] => 2
[city] => Szeged
[population] => 160000
[post_code] => 33356
)
)
If you can rely on the cities and post codes to be equal in length and sorted, you could just do something like this:
<?php
$cities = array(
array("id"=>1,"city"=>"Budapest","Population"=>"1700000"),
array("id"=>2,"city"=>"Szeged","Population"=>"160000")
);
$cityPostCode = array(
array("name"=>"Budapest","post_code"=>12345),
array("name"=>"Szeged","post_code"=>33356)
);
for($i = 0; $i < count($cities); $i++){
$cities[$i]['post_code'] = $cityPostCode[$i]['post_code'];
}
print_r($cities);
Other wise you could do something more dyanmic like:
function _parsePostCode($targetName,$targetArr){
foreach($targetArr as $el){
if($el['name'] == $targetName){
return $el['post_code'];
}
}
return false;
}
for($i = 0; $i < count($cities); $i++){
$cities[$i]['post_code'] = _parsePostCode($cities[$i]['city'],$cityPostCode);
}
print_r($cities);
As an alternative you can use 'reference' PHP in foreach loop as follows
$city = array(
0 => array(
'id' => 1,
'city' => "Budapest",
'population' => 1700000
),
1 => array(
'id' => 2,
'city' => "Szeged",
'population' => 160000
)
);
$city_postcode = array(
0 =>array(
'name' => 'Budapest',
'post_code' => 12345
),
1 => array(
'name' => 'Szeged',
'post_code' => 33356
)
);
foreach ($city as $ckey => &$cval) {
$cval['post_code'] = $city_postcode[$ckey]['post_code'];
}
unset($cval);
var_dump($city);
You can use this simple approach :
<?php
$city = array(
0 => array(
'id' => 1,
'city' => "Budapest",
'population' => 1700000
),
1 => array(
'id' => 2,
'city' => "Szeged",
'population' => 160000
)
);
$city_postcode = array(
0 => array(
'name' => 'Budapest',
'post_code' => 12345
),
1 => array(
'name' => 'Szeged',
'post_code' => 33356
)
);
function apply_post_code(&$item, $key, $postcode)
{
$item['post_code'] = $postcode[ $key ][ 'post_code' ];
}
array_walk($city, 'apply_post_code', $city_postcode);
var_dump($city);
Note that the $city variable has been passes by reference
I need to convert the below 2d array in to specified 2d array format. Array contains multiple parent and multiple child array. Also, have tried to convert the code, but am not getting the expected output.
This is the code what i have tried,
$a1 = array(
'0' =>
array(
'banner_details' =>
array(
'id' => 2,
'section_id' => 24
),
'slide_details' =>
array(
0 => array(
'id' => 74,
'name' => 'Ads1'
),
1 => array(
'id' => 2,
'name' => 'Ads2'
)
)
),
'1' =>
array(
'banner_details' =>
array(
'id' => 106,
'section_id' => 92
),
'slide_details' =>
array(
0 => array(
'id' => 2001,
'name' => 'Adv1'
),
1 => array(
'id' => 2002,
'name' => 'Adv2'
)
)
)
);
$s = [];
for($i = 0; $i<2; $i++) {
foreach($a1[$i]['slide_details'] as $vs){
$s[] = $vs;
}
}
My output:
Array
(
[0] => Array
(
[id] => 74
[name] => Ads1
)
[1] => Array
(
[id] => 2
[name] => Ads2
)
[2] => Array
(
[id] => 2001
[name] => Adv1
)
[3] => Array
(
[id] => 2002
[name] => Adv2
)
)
Expected output:
Array
(
[24] => Array
(
[0] => 74
[1] => 2
)
[92] => Array
(
[0] => 2001
[1] => 2002
)
)
please check the above code and let me know.
Thanks,
You can apply next simple foreach loop with help of isset() function:
foreach($a1 as $data){
if (isset($data['banner_details']['section_id'])){
$s[$data['banner_details']['section_id']] = [];
if (isset($data['slide_details'])){
foreach($data['slide_details'] as $row){
$s[$data['banner_details']['section_id']][] = $row['id'];
}
}
}
}
Demo
If you know that indexes like banner_details or slide_details or section_id will be there always then you can skip isset() in if statements.
You can use array_column function for simple solution:
$result = [];
foreach ($a1 as $item)
{
$result[$item['banner_details']['section_id']] = array_column($item['slide_details'], 'id');
}
var_dump($result);
I have this type of array
$arr = array(
0 => array(
0 => array(
'name' => 'test1',
'country' => 'abc'
)
1 => array(
'name' => 'test2',
'country' => 'xyz'
)
)
1 => array(
'name' => 'test3',
'country' => 'pqr'
)
);
How can I make all arrays as parallel arrays. So that all sub arrays are parallel to each other without using any loop.
Like this
$arr = array(
0 => array(
'name' => 'test1',
'country' => 'abc'
)
1 => array(
'name' => 'test2',
'country' => 'xyz'
)
2 => array(
'name' => 'test3',
'country' => 'pqr'
)
);
Any help is much appreciated. !
A dynamic version of Nigel's code would be to loop the array and merge each subarray.
$new = [];
foreach($arr as $subarr){
$new = array_merge($new, $subarr);
}
var_dump($new);
https://3v4l.org/np2ZD
You could simply merge the arrays...
$out = array_merge($arr[0], [$arr[1]]);
print_r($out);
Which gives...
Array
(
[0] => Array
(
[name] => test1
[country] => abc
)
[1] => Array
(
[name] => test2
[country] => xyz
)
[2] => Array
(
[name] => test3
[country] => pqr
)
)
Below is my array which i have printed:-
I want only the product_image from the array in loop
Array
(
[0] => Array
(
[product_option_id] => 247
[product_id] => 66
[product_option_value] => Array
(
[0] => Array
(
[product_option_value_id] => 42
[color_product_id] => 54
[name] => Pink
[product_image] => catalog/demo/teddy/03.jpg
[image] => http://192.168.15.9/Kids_stores/image/cache/catalog/axalta-ral-3015-light-pink-polyester-30-matt-powder-coating-20kg-box--1447-p-50x50.jpg
[price] =>
[price_prefix] => +
)
[1] => Array
(
[product_option_value_id] => 41
[color_product_id] => 67
[name] => Light Brown
[product_image] => catalog/Teddies/12-Baby-teddy/05.jpg
[image] => http://192.168.15.9/Kids_stores/image/cache/catalog/option-color/light_brown-50x50.jpg
[price] =>
[price_prefix] => +
)
[2] => Array
(
[product_option_value_id] => 43
[color_product_id] => 68
[name] => Cream
[product_image] => catalog/Teddies/12-Baby-teddy/11.jpg
[image] => http://192.168.15.9/Kids_stores/image/cache/catalog/option-color/cream-images-50x50.jpg
[price] =>
[price_prefix] => +
)
)
[option_id] => 5
[name] => COLOR
[type] => image
[value] =>
[required] => 0
)
)
Try this,
foreach($array as $val)
{
echo $val['product_image'];
}
Solution for your edited input:-
$image_array = array();
foreach ($your_array as $arr){
$image_array[] = array_column($arr['product_option_value'],'product_image');
}
Output:- https://eval.in/657966
You can take the array array_column and make it like this
$records = array (
array (
// your array
)
);
$variable = array_column($records, 'image');
echo $variable;
<?php $samples=$data['options'][0][product_option_value];
$product_image = array_column($samples, 'product_image');
echo'<pre>'; print_r($product_image );
?>
foreach($array as $key => $val){
if($key == 'product_image'){
echo "<img src='".$val."' />";
}
}
Try
You have to foreach the inner array:
foreach($array[product_option_value] as $val)
{
echo $val['product_image'];
}
Solution One:
<?php
$req_image=array();
$req_image[] = array_column($resultant_array, 'product_image');
print_r($req_image); // This will print all the images that are grouped under the array().
?>
Example:
The below is the PHP code and the sample output that you can obtain using the array_column().
PHP:
<?php
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe'
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith'
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones'
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe'
)
);
$lastNames = array_column($records, 'last_name', 'id');
Output:
If we call print_r() on $lastNames, you’ll see a resulting array that looks a bit like this:
Array
(
[2135] => Doe
[3245] => Smith
[5342] => Jones
[5623] => Doe
)
Solution Two: (As per requirement at last)
You can iterate the single key value alone in the foreach so that you can get the required parameter that you need.
foreach($resultant_array as $single_array)
{
foreach($single_array['product_option_value'] as $inner_array)
{
echo $inner_array['product_image']; // This will print the u=mage name that you need.
}
}
If you want one specified key and want minimal assumptions about array structure shoud use array_walk_recursive like this
$result = [];
array_walk_recursive($input,function ($value,$key) use (&$result) {
if ( 'product_image' == $key) {
$result[] = $value;
}
});
I have an array of form:
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe',
)
);
I want output like this :
EDIT:
Array
( array('first_Name' => John),
array('first_Name'=> Sally),
array('first_Name'=> Jane),
array('first_Name'=> Peter)
);
Can this be achieved??
You cannot do this since you can't have duplicate keys in an array.
Here is a related question: How to allow duplicate keys in a PHP array?
This article explains how PHP stores array internally: http://nikic.github.io/2012/03/28/Understanding-PHPs-internal-array-implementation.html.
Answer after your edit:
$arr = array();
foreach($records as $value) {
$arr[] = array('first_name' => $value['first_name']);
}
print_r($arr);
You can achieve your (edited) question like this:
$new_array = array();
foreach($records as $record)
$new_array[] = array('first_Name'=>$records['first_name']);
try this
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe',
)
);
$tmp = array('first_name' => '');
foreach ($records as &$record) {
$record = array_intersect_key($record, $tmp);
// or $record = array('first_name' => $record['first_name']);
}
unset($record);
var_dump($records);
If you want to array with in the array means, surely it will generated with index key, like this
Array
( '0' => array('first_Name' => John),
'1' => array('first_Name'=> Sally),
'2' => array('first_Name'=> Jane),
'3' => array('first_Name'=> Peter)
);
Try this one,
foreach($records as $record) {
$name_array[] = Array('first_Name' =>$record['first_name']);
}
print_r($name_array);
Your output will be,
Array
(
[0] => Array
(
[first_Name] => John
)
[1] => Array
(
[first_Name] => Sally
)
[2] => Array
(
[first_Name] => Jane
)
[3] => Array
(
[first_Name] => Peter
)
)
To get your desired output you can use array_map, though you can get similar output with array_column which is new in PHP 5.5.
With array_map (http://3v4l.org/v8Y8Z):
<?php
$firstNames = array_map(function($record) {
return ['first_name' => $record['first_name']];
}, $records);
With array_column (http://3v4l.org/ohnGu):
$firstNames = array_column($records, 'first_name');
Note: array_column doesn't make subarrays with the first_name key.
you can try this one
$arr_output = array();
foreach($records as $key=>$arr)
{
$arr_output['id'][] = $arr['id'];
$arr_output['first_name'][] = $arr['first_name'];
$arr_output['last_name'][] = $arr['last_name'];
}
print_r($arr_output['first_name']); // display all first names
print_r($arr_output); // display complete output array.
Output :
Array
(
[id] => Array
(
[0] => 2135
[1] => 3245
[2] => 5342
[3] => 5623
)
[first_name] => Array
(
[0] => John
[1] => Sally
[2] => Jane
[3] => Peter
)
[last_name] => Array
(
[0] => Doe
[1] => Smith
[2] => Jones
[3] => Doe
)
)
Demo
This is not possible, because you cannot have multiple elements of the same key in an associative array.
