Assume this array:
Array ( [0] => Array ( [id] => 1171 [product_id] => 140 [fileid] => 479717 [purchid] => 847 [cartid] => 833 [uniqueid] => f100c3b3a853202fb6559fbacf025a6aa07f52c7 [downloads] => 99998 [ip_number] => [active] => 1 [datetime] => 2015-06-02 20:10:05 )
[1] => Array ( [id] => 1172 [product_id] => 140 [fileid] => 313624 [purchid] => 847 [cartid] => 833 [uniqueid] => f00a3c91378ad469f333abeec64753b275f10670 [downloads] => 99999 [ip_number] => [active] => 1 [datetime] => 2015-06-02 20:10:05 )
[2] => Array ( [id] => 1173 [product_id] => 140 [fileid] => 313618 [purchid] => 847 [cartid] => 833 [uniqueid] => ac125595e2dbca6a086261434582f6e7dfc5638e [downloads] => 99999 [ip_number] => [active] => 1 [datetime] => 2015-06-02 20:10:05 )
[3] => Array ( [id] => 1174 [product_id] => 140 [fileid] => 313526 [purchid] => 847 [cartid] => 833 [uniqueid] => 3e6123e0a4453de71dec91a177f5b34217625680 [downloads] => 99999 [ip_number] => [active] => 1 [datetime] => 2015-06-02 20:10:05 ))
I want to "extract" the [0] array and use it for something else BUT it has to be conditioned.
I said the 0 element because it has the fileid = 479717 the one that i want.
So i`m looking at extracting the array (in my case [0]) that has filed = $myvalue. Where i can set $myvalue to whatever i want.
Does this fits your needs ?
function findById($id, $arrayOfArrays){
foreach ( $arrayOfArrays as $contents )
if ( $contents['id'] == $id ) return $contents;
}
function filter($fileid, array $array) {
foreach ($array as $key => $value) {
if ($value['fileid'] === $fileid) {
return $value;
}
}
}

I need to subtract the qt from two arrays based on id and type, keeping the array complete.
How do I do in php to be able to subtract these arrays?
I have 2 arrays:
=> this is the first array with multiple key "down"
Array
(
[0] => Array
(
[id] => 26
[loc] => 1
[type] => down
[qt] => 12
)
[1] => Array
(
[id] => 32
[loc] => 1
[type] => down
[qt] => 34
)
[2] => Array
(
[id] => 26
[loc] => 2
[type] => down
[qt] => 5
)
[3] => Array
(
[id] => 86
[loc] => 3
[type] => down
[qt] => 45
)
[4] => Array
(
[id] => 23
[loc] => 9
[type] => down
[qt] => 3
)
[5] => Array
(
[id] => 23
[loc] => 3
[type] => down
[qt] => 99
)
)
=> this is the second array with multiple key "up"
Array
(
[0] => Array
(
[id] => 26
[loc] => 1
[type] => up
[qt] => 5
)
[1] => Array
(
[id] => 86
[loc] => 3
[type] => up
[qt] => 27
)
[2] => Array
(
[id] => 23
[loc] => 9
[type] => up
[qt] => 3
)
)
=> I need cubtract "qt" (if "id" and "loc" are the same then subtract the "qt")
Array
(
[0] => Array
(
[id] => 26
[loc] => 1
[type] => total
[qt] => 7
)
[1] => Array
(
[id] => 32
[loc] => 1
[type] => total
[qt] => 34
)
[2] => Array
(
[id] => 26
[loc] => 2
[type] => total
[qt] => 5
)
[3] => Array
(
[id] => 86
[loc] => 3
[type] => total
[qt] => 18
)
[4] => Array
(
[id] => 23
[loc] => 9
[type] => total
[qt] => 0
)
[5] => Array
(
[id] => 23
[loc] => 3
[type] => down
[qt] => 99
)
)
Try this out
function findMatch($array, $id, $loc)
{
foreach ($array as $key => $item) {
if ($item["id"] == $id and $item["loc"] == $loc) {
return $key;
}
}
return false;
}
$total = [];
foreach($down as $d) {
$matched = findMatch($up, $d["id"], $d["loc"]);
if($matched !== false){
$total[] = array_replace($d, [
"type" => "total",
"qt" => ($d["qt"] - $up[$matched]["qt"])
]);
} else {
$total[] = array_replace($d, ["type" => "total"]);
}
}
print_r($total);
I have an array of arrays that I need to consolidate into another array.
I have tried mapping over it, matching object_id, and gathering all account_ids for said object_id, but all my attempts are not even close as I am trying to learn PHP
This is the original array
[0] => Array
(
[rank] => 0
[id] => 6
[object_id] => 3
[account_id] => 13
)
[1] => Array
(
[rank] => 1
[id] => 7
[object_id] => 3
[account_id] => 565
)
[2] => Array
(
[rank] => 2
[id] => 1823
[object_id] => 825
[account_id] => 563
)
[3] => Array
(
[rank] => 3
[id] => 1824
[object_id] => 825
[account_id] => 564
)
[4] => Array
(
[rank] => 4
[id] => 1825
[object_id] => 825
[account_id] => 565
)
[5] => Array
(
[rank] => 5
[id] => 7187
[object_id] => 3113
[account_id] => 564
)
[6] => Array
(
[rank] => 6
[id] => 7188
[object_id] => 3113
[account_id] => 565
)
This is the desired result
[3] => [13, 565],
[825] => [563, 564, 565],
[3113] => [564, 565],
You need to create a new array by using object_id index.
Example:
<?
$array = array(
array('rank'=>0,'id'=>6,'object_id'=>3,'account_id'=>13),
array('rank'=>1,'id'=>7,'object_id'=>3,'account_id'=>565),
array('rank'=>2,'id'=>1823,'object_id'=>825,'account_id'=>563),
array('rank'=>3,'id'=>1824,'object_id'=>825,'account_id'=>564),
array('rank'=>4,'id'=>1825,'object_id'=>825,'account_id'=>565),
array('rank'=>5,'id'=>7187,'object_id'=>3113,'account_id'=>564),
array('rank'=>6,'id'=>7188,'object_id'=>3113,'account_id'=>565),
);
$newArray = array(); // initiliaze array
foreach ($array as $key => $value) {
$newArray[$value['object_id']][] = $value['account_id']; // save it in group
}
echo "<pre>";
print_r($newArray); // result
?>
Running Example
I have the following array:
Array
(
[0] => Array
(
[Import] => Array
(
[id] => 1
[category_id] => 2
[product_id] => 2
[amount] => 50
[cost] => 8320
[comment] => transportation and others cost: 100
[created] => 2015-06-23 19:21:10
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 1
[confirmed] => 2
[canceled] => 0
)
)
[1] => Array
(
[Import] => Array
(
[id] => 2
[category_id] => 2
[product_id] => 2
[amount] => 15
[cost] => 3000
[comment] =>
[created] => 2015-06-22 18:10:36
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 1
[confirmed] => 2
[canceled] => 0
)
)
[2] => Array
(
[Import] => Array
(
[id] => 3
[category_id] => 2
[product_id] => 1
[amount] => 15
[cost] => 2000
[comment] =>
[created] => 2015-06-23 19:20:15
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 0
[confirmed] => 0
[canceled] => 0
)
)
)
I want to remove duplicate value of same product_id inside [Import][product_id] but want sum [Import][amount]. My expected array is:
Array
(
[0] => Array
(
[Import] => Array
(
[id] => 1
[category_id] => 2
[product_id] => 2
[amount] => 65
[cost] => 8320
[comment] => transportation and others cost: 100
[created] => 2015-06-23 19:21:10
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 1
[confirmed] => 2
[canceled] => 0
)
)
[1] => Array
(
[Import] => Array
(
[id] => 3
[category_id] => 2
[product_id] => 1
[amount] => 15
[cost] => 2000
[comment] =>
[created] => 2015-06-23 19:20:15
)
[0] => Array
(
[total_sell] => 10
[no_contact] => 0
[confirmed] => 0
[canceled] => 0
)
)
)
It will be really a gift if anyone give a function to solve this issue.
$filteredArray = [];
foreach ($array as $productData) {
if (isset($filteredArray[$productData['Import']['product_id']])) {
$filteredArray[$productData['Import']['product_id']]['Import']['amount'] += $productData['Import']['amount'];
}
else {
$filteredArray[$productData['Import']['product_id']] = $productData;
}
}
print_r($filteredArray);
Ah.. forgot to mention - $array is Your base array.
/**
* Removes duplicate summing amount from products array
*
* #param array $array
* #return array
*/
function removeDuplicates($array)
{
$idsCount = array();
foreach ($array as $key => $value) {
$idsCount[$value['Import']['product_id']]['count'] += 1;
$idsCount[$value['Import']['product_id']]['sum'] += $value['Import']['amount'];
if ($idsCount[$value['Import']['product_id']]['count'] > 1) {
unset($array[$key]);
$array[$idsCount[$value['Import']['product_id']]['key']]['Import']['amount'] = $idsCount[$value['Import']['product_id']]['sum'];
} else {
$idsCount[$value['Import']['product_id']]['key'] = $key;
}
}
return $array;
}
i know it looks crazy but is formatted on your specific array.
Ok so here is my first array:
(
[1] => Array
(
[27] => Array
(
[product_id] => 27
[type] => hardware
[step_number] => 1
)
[372] => Array
(
[product_id] => 372
[type] => hardware
[step_number] => 1
)
[92] => Array
(
[product_id] => 92
[type] => hardware
[step_number] => 1
)
)
[2] => Array
(
[335] => Array
(
[product_id] => 335
[type] => hardware
[step_number] => 2
)
[62] => Array
(
[product_id] => 62
[type] => hardware
[step_number] => 2
)
[356] => Array
(
[product_id] => 356
[type] => hardware
[step_number] => 2
)
)
and here is my second array
(
[1] => Array
(
[655] => Array
(
[product_id] => 655
[type] => optional
[step_number] => 1
)
[54] => Array
(
[product_id] => 54
[type] => optional
[step_number] => 1
)
[554] => Array
(
[product_id] => 554
[type] => optional
[step_number] => 1
)
)
[2] => Array
(
[33] => Array
(
[product_id] => 33
[type] => optional
[step_number] => 2
)
[612] => Array
(
[product_id] => 612
[type] => optional
[step_number] => 2
)
[5] => Array
(
[product_id] => 5
[type] => optional
[step_number] => 2
)
)
[3] => Array
(
[444] => Array
(
[product_id] => 444
[type] => optional
[step_number] => 3
)
[6] => Array
(
[product_id] => 6
[type] => optional
[step_number] => 3
)
[53] => Array
(
[product_id] => 53
[type] => optional
[step_number] => 3
)
)
Basically what i need is the second array appended to the end of the first array with the keys of the first array preserved the keys and changing the step_number to the new key so the final keys looks like
(
[1] => Array
(
[27] => Array
(
[step_number] => 1)
....
[2] => Array
(
[335] => Array
(
[step_number] => 2)
....
[3] => Array
(
[655] => Array
(
[step_number] => 3)
....
[4] => Array
(
[33] => Array
(
[step_number] => 4)
....
[5] => Array
(
[444] => Array
(
[step_number] => 5)
....
but when i do
$all = array_merge($first, $second);
the keys are
(
[0] => Array
[1] => Array
[2] => Array
[3] => Array
[4] => Array
Is that possible to do....
Try array_merge_recursive .. http://php.net/array_merge_recursive
This is also from the manual on array_splice if you're just looking to append your 2nd array onto the first (http://php.net/manual/en/function.array-push.php):
array_splice($first, count($first), 0, $second);
Iterating over the first set of keys, then using the Union array operator should do the trick.
//$first = array(...);
//$second = array(...);
foreach ($second as $key => $value)
{
if (!isset($first[$key]))
{
$first[$key] = array();
}
$first[$key] += $value;
}

I want the result by media_format = DVD so the whole array is gone, is there anyway to delete an array or remove it?
The same way you "delete" any variable:
unset($array[$index]);
