I try to convert an array to an indexed array but none of the array functions I found can solve my problem
I have this array
Array(
[no_discount] => 0
[manufacturers_id] => 2
[id] => 3
)
Array(
[no_discount] => 1
[manufacturers_id] => 1
[id] => 1
)
and I would like to convert this array to
Array(
[0] => Array(
[no_discount] => 0
[manufacturers_id] => 2
[id] => 3
)
[1] => Array(
[no_discount] => 1
[manufacturers_id] => 1
[id] => 1
)
)
Is there a simple array function or do I have use a loop?
loop - or write you own ..
$tgt = [];
foreach ( $src as $t) { $tgt[] = $t; }
I'm not sure how you are getting your array but will this work for you?
$main_array = array();
$one = Array(
"no_discount" => 0,
"manufacturers_id" => 2,
"id" => 3,
);
$two = Array(
"no_discount" => 1,
"manufacturers_id" => 1,
"id" => 1,
);
array_push($main_array, $one);
array_push($main_array, $two);
print_r($main_array);

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 2 arrays one contains just a list of email address and the other contains emails and names.
The list of emails in array1 are stored in a database and the other array is a list of new and current users.
I have tried using array_diff however this only seems to work if I specify in my loop that I just want emails.
$array1 = array(
0 => 'dave#daveshouse.com',
1 => 'sam#samshouse.com',
2 => 'jim#jimshouse.com',
3 => 'olly#ollyshouse.com',
4 => 'tom#tomshouse.com'
);
$array2 = array(
0 => array(
0 => 'tom',
1 => 'tom#tomshouse.com'
),
1 => array(
0 => 'james',
1 => 'james#jameshouse.com'
),
2 => array(
0 => 'marvin',
1 => 'marvin#marvinshouse.com'
),
3 => array(
0 => 'jane',
1 => 'jane#janeshouse.com'
),
);
$array2emails = array();
foreach ($array2 as $item) {
$array2emails[] = $item[1];
}
$result = array_diff($array2emails, $array1);
$results gives me
Array
(
[1] => james#jameshouse.com
[2] => marvin#marvinshouse.com
[3] => jane#janeshouse.com
)
however I need to get this:
Array
(
[1] => array(
[0] => james
[1] => james#jameshouse.com
)
[2] => array(
[0] => marvin
[1] => marvin#marvinshouse.com
)
[3] => array(
[0] => jane
[1] => jane#janeshouse.com
)
)
Any help would be much appreciated. Thanks
Since the array returned by array_diff has the same keys as the original array, you can use that to get the elements of the original array back, with array_intersect_key.
$array1 = array(
0 => 'dave#daveshouse.com',
1 => 'sam#samshouse.com',
2 => 'jim#jimshouse.com',
3 => 'olly#ollyshouse.com',
4 => 'tom#tomshouse.com'
);
$array2 = array(
0 => array(
0 => 'tom',
1 => 'tom#tomshouse.com'
),
1 => array(
0 => 'james',
1 => 'james#jameshouse.com'
),
2 => array(
0 => 'marvin',
1 => 'marvin#marvinshouse.com'
),
3 => array(
0 => 'jane',
1 => 'jane#janeshouse.com'
),
);
$array2emails = array_column($array2, 1);
$keys = array_diff($array2emails, $array1);
$result = array_intersect_key($array2, $keys);
print_r($result);
Result:
Array
(
[1] => Array
(
[0] => james
[1] => james#jameshouse.com
)
[2] => Array
(
[0] => marvin
[1] => marvin#marvinshouse.com
)
[3] => Array
(
[0] => jane
[1] => jane#janeshouse.com
)
)
$array1 = array(
0 => 'dave#daveshouse.com',
1 => 'sam#samshouse.com',
2 => 'jim#jimshouse.com',
3 => 'olly#ollyshouse.com',
4 => 'tom#tomshouse.com'
);
$array2 = array(
0 => array(
0 => 'tom',
1 => 'tom#tomshouse.com'
),
1 => array(
0 => 'james',
1 => 'james#jameshouse.com'
),
2 => array(
0 => 'marvin',
1 => 'marvin#marvinshouse.com'
),
3 => array(
0 => 'jane',
1 => 'jane#janeshouse.com'
),
);
$diffs = array();
foreach ($array2 as $item) {
if (!in_array($item[1], $array1)) {
$diffs[] = $item;
}
}
Since you are using a foreach loop why not create the array there?
As long as the arrays are not to long this will word nicely. I even took the original key into the new array. So you will be able to do other comparison methods to it.
$array1 = [
0 => 'dave#daveshouse.com',
1 => 'sam#samshouse.com',
2 => 'jim#jimshouse.com',
3 => 'olly#ollyshouse.com',
4 => 'tom#tomshouse.com'
];
$array2 = [
0 => [
0 => 'tom',
1 => 'tom#tomshouse.com'
],
1 => [
0 => 'james',
1 => 'james#jameshouse.com'
],
2 => [
0 => 'marvin',
1 => 'marvin#marvinshouse.com'
],
3 => [
0 => 'jane',
1 => 'jane#janeshouse.com'
],
];
$arrayExits = [];
foreach ($array2 as $key => $item) {
if(in_array($item[1], $array1)) {
$arrayExits[$key] = $item;
}
}
print_r($arrayExits);
Use array_filter function.
function filterEmail($value, $key){
global $array1;
return !in_array($value[1], $array1);
}
$emailDiff = array_filter($array2, 'filterEmail' , ARRAY_FILTER_USE_BOTH );
print_r($emailDiff );

I have these two arrays and I want to combine them into one. Using the duplicate values from 0,1 in the second array. Below is an example of how I would want it to look. I hope someone can help.
Array(
[201500001] => Array

I rewrote your various arrays as valid arrays. Other than that, I think that what you are looking for is to use array_intersect. This works for me:
$source = array(
201500001 => array(
0 => 1003123603,
1 => 3062226597
),
201500002 => array(
0 => 3067005512
)
);
$target = array(
1127893457 => array(
0 => 1003123603
),
1127893467 => array(
0 => 1003133106,
1 => 3067005512
),
1127893443 => array(
0 => 1004146393,
1 => 3062226597
),
1127893246 => array(
0 => 1003154423,
1 => 5149282937
)
);
$expected = array(
1127893457 => array(
0 => 1003123603,
2 => 201500001
),
1127893467 => array(
0 => 1003133106,
1 => 3067005512,
2 => 201500002
),
1127893443 => array(
0 => 1004146393,
1 => 3062226597,
2 => 201500001
),
1127893246 => array(
0 => 1003154423,
1 => 5149282937
)
);
$newArray = [];
foreach ($target as $targetKey => $targetValue) {
foreach ($source as $sourceKey => $sourceValue) {
if (array_intersect($sourceValue, $targetValue)) {
$targetValue[2] = $sourceKey;
}
$newArray[$targetKey] = $targetValue;
}
}
echo ($newArray === $expected) ? "Match!" : "Miss." . PHP_EOL;
Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.
<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>
I have 2 arrays:
Array ( [0] => Array ( [intTrackId] => 41 [intAverageRating] => 10 [bolNewRelease] => 0 [dtDateAdded] => 2013-03-08 17:32:26 ) [1] => Array ( [intTrackId] => 1 [intAverageRating] => 7 [bolNewRelease] => 0 [dtDateAdded] => 2013-03-08 18:54:35 ))
Array ( [0] => Array ( [intTrackId] => 41 [intAverageRating] => 5.5000 [bolNewRelease] => 1 [dtDateAdded] => 2014-03-25T09:39:28Q ) [1] => Array ( [intTrackId] => 361 [intAverageRating] => 8.0000 [bolNewRelease] => 1 [dtDateAdded] => 2014-03-25T09:39:28Q ))
I want to remove the items in the second which have a matching track ID in the first. So in this example, I would get:
Array ( [0] => Array ( [intTrackId] => 361 [intAverageRating] => 8.0000 [bolNewRelease] => 1 [dtDateAdded] => 2014-03-25T09:39:28Q ))
Is this possible with array_filter or is this a little complex for that?
Just use array_udiff() - it's intended to do this:
$one = Array (
0 => Array ('intTrackId' => 41, 'intAverageRating' => 10, 'bolNewRelease' => 0, 'dtDateAdded' => '2013-03-08 17:32:26' ),
1 => Array ('intTrackId' => 1, 'intAverageRating' => 7, 'bolNewRelease' => 0, 'dtDateAdded' => '2013-03-08 18:54:35' )
);
$two = Array (
0 => Array ('intTrackId' => 41, 'intAverageRating' => 5.5000, 'bolNewRelease' => 1, 'dtDateAdded' => '2014-03-25T09:39:28Q' ),
1 => Array ('intTrackId' => 361, 'intAverageRating' => 8.0000, 'bolNewRelease' => 1, 'dtDateAdded' => '2014-03-25T09:39:28Q' )
);
$result = array_udiff($two, $one, function($x, $y)
{
return $x['intTrackId']-$y['intTrackId'];
});
Yes it can be done with array_filter:
$array1 = array(...);
$array2 = array(...);
$newArray = array_filter($array2, function($item) use ($array1){
foreach($array1 as $elem){
if($item['intTrackId'] == $elem['intTrackId']){
return false;
}
}
return true;
});
I would first create a loop and store all track IDs from the first array in a separate array.
Then I'd loop over the second array and delete those keys that exist in the track ID array.
$track_ids = array();
foreach($array1 as $index => $items) {
$track_ids[$items['intTrackId']] = $index;
}
foreach($array2 as $items) {
if (isset($track_ids[$items['intTrackId']])) {
unset($array2[$track_ids[$items['intTrackId']]]);
}
}
$series = array();
while($row = mysql_fetch_assoc($result)) {
$series[$row["data_id"]][] = $row;
}
The output from a print_r on $series yields for two example series:
Array (
[1] => Array ( [0] => Array ( [id] => 1 [data_id] => 1 [time_id] => 1
[data] => 1 ) [1] => Array ( [id] => 2 [data_id] => 1 [time_id] => 2
[data] => 3 ) )
[2] => Array ( [0] => Array ( [id] => 6 [data_id] => 2 [time_id] => 1
[data] => 7 ) [1] => Array ( [id] => 7 [data_id] => 2 [time_id] => 2
[data] => 4 ) )
My question: how do I unset the multidimensional array so it contains only [data] and none of the other keys? I still want $series to contain [1] and [2] but I do not want the respective sub-arrays to contain any other keys other than [data].
In fact, since I am reducing the subarrays to contain a single key, I would really like to get rid of the subarrays altogether so that I have two arrays:
$series[1] = array(1,3) and
$series[2] = array(7,4)
Try this :
$series = array();
while($row = mysql_fetch_assoc($result)) {
$series[$row["data_id"]][] = $row['data'];
}
I think you can loop in your array and build a new one keeping only data details
$array = array ('1' => array ( '0' => array ( 'id' => 1, 'data_id' => 1, 'time_id' => 1, 'data' => 1 ), '1' => array ( 'id' => 2, 'data_id' => 1, 'time_id' => 2, 'data' => 3 ), ),
'2' => array ( '0' => array ( 'id' => 6, 'data_id' => 2, 'time_id' => 1, 'data' => 7 ), '1' => array ( 'id' => 7, 'data_id' => 2, 'time_id' => 2, 'data' => 4 ) ));
$i= 0;
$n= 0;
$series = array();
foreach($array as $dato)
{
$series[$i] = array();
foreach($dato as $data)
{
foreach($data as $key => $value)
{
if($key == 'data')
{
$series[$i][$n] = $value;
$n++;
}
}
}
$n = 0;
$i++;
}
var_dump($series);
This will output
array (size=2)
0 =>
array (size=2)
0 => int 1
1 => int 3
1 =>
array (size=2)
0 => int 7
1 => int 4
