I have an array and I'm trying to count the number of objects in the array where the the object key 'Value' is not 0.
array (
0 =>
array (
'name' => 'item[110189]',
'value' => '0',
'primary_key' => '110189',
),
1 =>
array (
'name' => 'item[110190]',
'value' => '50',
'primary_key' => '110190',
),
2 =>
array (
'name' => 'item[110191]',
'value' => '0',
'primary_key' => '110191',
),
3 =>
array (
'name' => 'item[110192]',
'value' => '0',
'primary_key' => '110192',
),
)
I've tried the following:
$input_items = array_filter($request->items, function($item){
$count = 0;
foreach($item as $i){
if(! $i['value'] == 0){
$count = $count + 1;
}
}
return $count;
}); // it will return an array
return $input_items;
I get an error saying invalid object 'Value' which to be honest I half expected.
Changed it this way:
$input_items = array_filter($arr, function ($item) {
return ($item['value'] != 0);
});
Full Code
<?php
$arr = array (
0 =>
array (
'name' => 'item[110189]',
'value' => '0',
'primary_key' => '110189',
),
1 =>
array (
'name' => 'item[110190]',
'value' => '50',
'primary_key' => '110190',
),
2 =>
array (
'name' => 'item[110191]',
'value' => '0',
'primary_key' => '110191',
),
3 =>
array (
'name' => 'item[110192]',
'value' => '0',
'primary_key' => '110192',
),
);
$input_items = array_filter($arr, function ($item) {
return ($item['value'] != 0);
});
print_r($input_items);
Output has only the non-zero entries:
Array
(
[1] => Array
(
[name] => item[110190]
[value] => 50
[primary_key] => 110190
)
)

You can use array_reduce:
print array_reduce($request->items, function($carry ,$item){
if($item['value'] != 0){
$carry++;
}
return $carry;
},0);

Hello i am trying to create data set like
Expected output:-
Array
(
[0] => Array
(
[sku] => sku
[variant_option_one_name] => Color
[variant_option_one_value] => Cyan
),
[1] => Array
(
[sku] => sku
[variant_option_one_name] => Color
[variant_option_one_value] => Red
)
)
but i am not sure what is missing in code.
Here is the code
$array = array(
0 => array(
'id_product_attribute' => '17615',
'id_product' => '2295',
'reference' => '',
'available_date' => '0000-00-00',
'vend_id' => null,
'id_shop' => '1',
'id_attribute_group' => '1',
'is_color_group' => '1',
'group_name' => 'Color',
'attribute_name' => 'Cyan',
'id_attribute' => '1',
),
1 => array(
'id_product_attribute' => '17616',
'id_product' => '2295',
'reference' => '',
'available_date' => '0000-00-00',
'vend_id' => null,
'id_shop' => '1',
'id_attribute_group' => '1',
'is_color_group' => '1',
'group_name' => 'Color',
'attribute_name' => 'Red',
'id_attribute' => '21',
),
);
$ids = array();
foreach ($array as $combinations) {
$ids['sku'] = 'sku';
$ids['variant_option_one_name'] = $combinations['group_name'];
$ids['variant_option_one_value'] = $combinations['attribute_name'];
}
print_r($ids);//
Here i am getting
Array
(
[sku] => sku
[variant_option_one_name] => Color
[variant_option_one_value] => Red
)
The above output i am getting. Seems like data is overwrite
Any correction to get both the data ?
I do not get both the colors in array. It
Thankyou
You're absolutely right, the values are being overwritten each time.
What you need to do is, each time you loop you should create a new array containing your values, and then assign that array to a new index inside the main array (so you get an array of arrays, like the expected output you've shown):
foreach ($array as $combinations) {
$arr = array();
$arr['sku'] = 'sku';
$arr['variant_option_one_name'] = $combinations['group_name'];
$arr['variant_option_one_value'] = $combinations['attribute_name'];
$ids[] = $arr;
}
Live Demo: http://sandbox.onlinephpfunctions.com/code/3a0cf7f8cbb994ef4192c1e23493bef397785937
foreach ($array as $combinations) {
array_push ($ids, [
'sku' => 'sku',
'variant_option_one_name' => $combinations['group_name'],
'variant_option_one_value' => $combinations['attribute_name']
]);
}
I have a nested array who is 4 levels deep.
I would like to replace the keys by numerical ones but not the meta level, this array should keep the alphabetical keys.
The array will have a lot of values and there will be more accounts like Marco Mueller, this is just a short example. It is important that it will keep the same nested structure, after its replaced by numerical keys.
$array = array (
'Marco Mueller' =>
array (
'meta' =>
array (
'accountName' => 'Marco Mueller',
'accountId' => '1',
'sum' => '3,659.06',
),
'Conrad, Ute' =>
array (
'meta' =>
array (
'customerName' => 'Conrad, Ute',
'customerId' => '8391',
'sum' => '457.59',
),
'Fidor Bank' =>
array (
'meta' =>
array (
'bankName' => 'Fidor Bank',
'bankKey' => 'FID',
'sum' => '457.59',
),
'H1-2019' =>
array (
'meta' =>
array (
'periodName' => 'H1-2019',
'periodId' => '5',
'sum' => '457.59',
),
),
),
),
),
);
The result should be
$array = array (
array (
'meta' =>
array (
'accountName' => 'Marco Mueller',
'accountId' => '1',
'sum' => '3,659.06',
),
'items' => array (
'meta' =>
array (
'customerName' => 'Conrad, Ute',
'customerId' => '8391',
'sum' => '457.59',
),
'items' =>
array (
'meta' =>
array (
'bankName' => 'Fidor Bank',
'bankKey' => 'FID',
'sum' => '457.59',
),
'items' => array (
'meta' =>
array (
'periodName' => 'H1-2019',
'periodId' => '5',
'sum' => '457.59',
),
),
),
array (
'meta' =>
array (
'periodName' => 'H2-2019',
'periodId' => '6',
'sum' => '600',
),
),
),
),
),
);
I solved my problem with this function, if anyone has an idea how to make this more elegant and efficient, your welcome!
private function getValues(array $array)
{
$newArray = [];
foreach ($array as $item) {
$meta = $item['meta'];
unset($item['meta']);
$arrayValues = array_values($item);
if (count($arrayValues) > 1 || count($arrayValues[0]) > 1) {
$arrayValues = $this->getValues($arrayValues);
}
if (!$arrayValues) {
$values = [
'meta' => $meta,
];
} else {
$values = [
'meta' => $meta,
'items' => $arrayValues,
];
}
$newArray[] = $values;
}
return $newArray;
}
$array1 = array(
[0] => array(
'id' => 'gdye6378399sjwui39',
'name' => 'Plate 1'
),
[1] => array(
'id' => 'xyz6378399sjwui39',
'name' => 'Plate 2'
),
[2] => array(
'id' => 'tr2e6378399sjwui39',
'name' => 'Plate 3'
)
)
and another array
$array2 = array(
[0] => array(
'id' => 'gdye6378399sjwui39',
'ETA' => '8'
),
[1] => array(
'id' => 'tr2e6378399sjwui39',
'ETA' => '9'
)
[2] => array(
'id' => 'xyz6378399sjwui39',
'ETA' => '5'
)
)
I want to compare the two arrays. I am doing it like this way:-
if(!empty($array2))
{
foreach($array1 as $ck => $cl)
{
foreach($array12 as $ued){
if($cl['id'] == $ued['id'])
{
$array1[$ck]['ETA'] = $ued['ETA'];
break;
}
}
}
What are the other better ways to do this? The order of the two arrays may vary, and so does the size.
If you index the second array by the id (using array_column()) you can get away without using the inner foreach() and just use isset()...
$match = array_column($array2, null, 'id');
foreach ( $array1 as $ck=>$cl) {
if ( isset($match[$cl['id']]) ) {
$array1[$ck]['ETA'] = $match[$cl['id']]['ETA'];
}
}
print_r($array1);
I have an multidimensional array like this:
$orders = array(
array(
'id' => '123',
'name' => 'John',
'lastname'=>'Carter',
'rate' => '1.0'
),
array(
'id' => '546',
'name' => 'Ben',
'lastname'=>'Wall',
'rate' => '0.25'
),
array(
'id' => '666',
'name' => 'John Bow',
'lastname'=>'Porter',
'rate' => '0.25'
),
array(
'id' => '156',
'name' => 'John',
'lastname'=>'Carter',
'rate' => '0.5'
)
);
and want make a function that will be delete duplicate rows that rate < 1.0. The result array should be:
$orders = array(
array(
'id' => '123',
'name' => 'John',
'lastname'=>'Carter',
'rate' => '1.0'
),
array(
'id' => '546',
'name' => 'Ben',
'lastname'=>'Wall',
'rate' => '0.25'
),
array(
'id' => '666',
'name' => 'John',
'lastname'=>'Porter',
'rate' => '0.25'
)
);
Not very beautiful and speed, but workable solution:
$a = array(...); // Your array
$hashstack = array_map(function($value) { return md5($value['name'] . $value['lastname']); }, $a);
$result = array_filter($a, function($value) use ($hashstack)
{
if ((float)$value['rate'] < 1.0) {
$count = 0;
foreach ($hashstack as $hash) {
if (md5($value['name'] . $value['lastname']) == $hash) {
$count++;
}
}
if ($count > 1) {
unset($value);
return;
}
}
return $value;
});
Result is the same of yours.
Edit: Second and good version here: http://ideone.com/zJ8vj
What do You mean by 'duplicated' - same 'rate' ?
Bellow example remove duplicated orders with same 'rate' and 'rate' < 1.0.
Is this what You need ?
$tmpOrders = array();
foreach($orders as $order) {
// Check only rate < 1.0
if((float)$order['rate'] < 1.0) {
// Check duplicate
$exists = false;
foreach($tmpOrders as $tmp) {
if($tmp['rate'] == $order['rate']) {
$exists = true;
break;
}
}
// Add if rate not exists
if(!$exists) {
$tmpOrders[] = $order;
}
}
// Add all with rate >= 1.0
else {
$tmpOrders[] = $order;
}
}
$orders = $tmpOrders;
echo "<pre>";
print_r($orders);
echo "<pre>";
Result:
Array
(
[0] => Array
(
[id] => 123
[name] => John
[lastname] => Carter
[rate] => 1.0
)
[1] => Array
(
[id] => 546
[name] => Ben
[lastname] => Wall
[rate] => 0.25
)
[2] => Array
(
[id] => 156
[name] => John
[lastname] => Carter
[rate] => 0.5
)
)
I'm having a problem lately that's driving me crazy. I have a multi-dimensional array like this:
$a = array(
'db' => array(
'0' => array(
'id' => '1',
'name' => 'test',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
),
'1' => array(
'id' => '2',
'name' => 'test2',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
)
'2' => array(
'id' => '3',
'name' => 'test',
'cat' => array(
'a' => '50',
'b' => '40',
'c' => '90'
),
'canvas' => '1'
)
)
);
And i want to search on it using a function like this: search('canvas = 1');
That would return all the arrays, child of db, that have a key canvas with the value of 1. Or, for example:
search('a = 15');
Would return all arrays that have a key, child of cat, named a and with a value of 15.
$a = array(
'db' => array(
'0' => array(
'id' => '1',
'name' => 'test',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
),
'1' => array(
'id' => '2',
'name' => 'test2',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
),
)
);
//checks if array $array contains element with $searchKey key, and $searchVal value
function arrayContains($array, $searchVal, $searchKey) {
if (!is_array($array))
return false;
foreach ($array as $key => $value) {
if ($key === $searchKey && $searchVal === $value)
return true;
if (is_array($value) && arrayContains($value, $searchVal, $searchKey))
return true;
}
return false;
}
function search($a, $search) {
list($searchKey, $searchVal) = explode('=', $search);
$result = array();
foreach($a as $val) {
if (arrayContains($val, $searchVal, $searchKey))
$result[] = $val;
}
return $result;
}
print_r(search($a['db'], "a=15"));
print_r(search($a['db'], "canvas=1"));
Which produces this output(outputs sub-arrays of $a['db'] which contain searched key=>value pair):
Array
(
[0] => Array
(
[id] => 1
[name] => test
[cat] => Array
(
[a] => 15
[b] => 20
[c] => 30
)
[canvas] => 2
)
[1] => Array
(
[id] => 2
[name] => test2
[cat] => Array
(
[a] => 15
[b] => 20
[c] => 30
)
[canvas] => 2
)
)
Array
(
[0] => Array
(
[id] => 3
[name] => test
[cat] => Array
(
[a] => 50
[b] => 40
[c] => 90
)
[canvas] => 1
)
)
Just check the below link if this can help you -
http://php.net/manual/en/function.array-search.php
It contains detailed documentation of php function array_search() and various user codes for searching in multi-dimensional array along with user reviews.
function search($array, $canvas)
{
$result = array();
foreach ($array as $k1 => $v1) {
foreach ($v1 as $k2 => $v2) {
if ($v2['canvas'] == $canvas) {
$result[] = $array[$k1][$k2];
}
}
}
return $result;
}
// $a = your array
print_r(search($a, 1));
