Im creating an array of products, each with an ID and score:
$savedProducts = array( 'product' => array("product_id" => $product_id,"product_score" => $score));
I want to be able to update the score by using the product_id as identifier.
I've tried:
foreach($savedProducts as $key => $val)
{
if ($val == $property_id )
{
$savedProducts[$key] = $score;
break;
}
}
Which keeps adding a new array item, rather than updating the original.
I think the issue is that my initial array setup then doesn't match the edited one.
Initial array:
Array
(
[product] => Array
(
[product_id] => 125026
[product_score] => 5
)
)
After trying to update score:
Array
(
[0] => Array
(
[product] => Array
(
[product_id] => 125026
[product_score] => 4
)
)
[1] => Array
(
[0] => Array
(
[product] => Array
(
[product_id] => 125026
[product_score] => 4
)
)
)
)
So it keeps addding elements, rather than updating the existing.
with PHP 5.5 use:
$savedProducts = array_column($savedProducts, NULL, 'product_id');
then you can access your product with:
$savedProducts[$product_id]
Please try this
foreach($savedProducts as $key => $val)
{
if($val['product_id'] == $property_id)
{
$savedProperties[$key]['product_score'] = $score;
break;
}
}

I have this code:
$order = wc_get_order( 988613 );
$product_array = array();
$daty = array();
$counter = 1;
foreach ($order->get_items() as $item_key => $item ){
$daty_dostaw = $item->get_meta('Daty dostaw');
$product_id = $item->get_product_id();
$daty_dostaw_explode = explode(',',$daty_dostaw);
$daty[$counter]['product_id'] = $product_id;
foreach($daty_dostaw_explode as $key => $data){
$daty[$counter]['data'][] = $data;
}
$counter++;
}
When I print it it shows me this
Array
(
[1] => Array
(
[product_id] => 988012
[data] => Array
(
[0] => 13-08-2022
[1] => 25-08-2022
[2] => 30-08-2022
)
)
[2] => Array
(
[product_id] => 988087
[data] => Array
(
[0] => 25-08-2022
[1] => 31-08-2022
[2] => 30-09-2022
)
)
)
I want to combine an array that have the same dates to display like this:
Array
( [1] => Array
(
[product_id] => array(988012, 988087)
[data] => Array
(
[0] => 25-08-2022
)
)
[2] => Array
(
[product_id] => 988012
[data] => Array
(
[0] => 13-08-2022
[1] => 30-08-2022
)
)
[3] => Array
(
[product_id] => 988087
[data] => Array
(
[0] => 31-08-2022
[1] => 30-09-2022
)
)
)
I want to merge the array those with the same dates. I don't know how to explain it exactly, above I showed what I would like to achieve. I have already written thousands of lines of code using foreach and have not been able to achieve this :(
Basically you want to convert product_id into an array if there are multiple products with the same date. I would search for such matches, create the merges, remove the elements from the individual occurrence or even the individual occurrence if it gets emptied. An example would be this:
$cachedDates = []; //Here we will store the dates we have gone through so far
foreach ($product_array as $key => $product) {
foreach ($product_array[$key]["data"] => $date) {
if (!in_array($date, $cachedDates)) {
//Creating a cache entry for this date
$cachedDates[$date] = ["keys" => [], "values" => []];
}
//Adding the key and product to the date's cache
$cachedDates[$date]["keys"][]= $key;
$cachedDates[$date]["values"][]= $product["product_id"];
}
}
//Adding the new items to $product_array and cleaning up items that become redundant
foreach ($cachedDates as $date => $entry) {
//We only merge items that have a not-unique date
if (count($entry["values"]) > 0) {
//adding a new item with the correct values and the date
$product_array[]= [
"product_id" => $entry["values"],
"data" => $date
];
//Cleanup
for ($index = 0; $index < count($entry["keys"]); $index++) {
//We remove the date from the data entry after finding its index
$removeIndex = array_search($date, $product_array[$entry["keys"][$index]]["data"]);
unset($product_array[$entry["keys"][$index]]["data"][$removeIndex]);
//If the data array is empty, then the whole product was already merged into some other item(s)
if (!count($product_array[$entry["keys"][$index]]["data"])) {
unset($product_array[$entry["keys"][$index]]);
}
}
}
}
The code above was untested, if you find issues with it and errors, then provide the appropriate PHP input instead of its print, even a json_encode result is good-enough
I have a multidimensional array as below. I wish to check if the key [type] is equal to "select". If so, I wish to display the value of key [value]. How do I actually output the value of key [value] which is "Section 100." In the code below, it only outputs the value "select".
array_walk_recursive( $product_extras, function ($value, $key ) {
if( $key === 'type' && $value == 'select' ) {
echo "[$value]"; //This outputs "select". But I actually need the value from key [value]
}
});
My array.
Array
(
[product_id] => 8928
[title] => Example of an Event
[groups] => Array
(
[8929] => Array
(
[8932] => Array
(
[type] => select
[label] => Section
[id] => pewc_group_8929_8932
[group_id] => 8929
[field_id] => 8932
[value] => Section 100
[flat_rate] => Array
(
)
)
)
)
)
If you`re able to pass these ids as parameters in that function you should be able to do something like:
$product_extras['groups'][$runtime_group_id][$runtime_field_id]
With this you should access
Array(
[type] => select
[label] => Section
[id] => pewc_group_8929_8932
[group_id] => 8929
[field_id] => 8932
[value] => Section 100
[flat_rate] => Array
(
using array_map() and recursive(call itself)
call myfunction and send each value inside the array
function yourOuterFunction(){
//your code....
//your array $product_extras .......
array_map("myfunction",$product_extras);
function myfunction($value) {
//search is array or not
if(is_array($value)) {
//search array key and value
if(array_key_exists("type",$value) && array_search("select",$value) == true){
echo "Condition true FOUND..";
print_r($value);
}
//if not found then call itself
else if(is_array($value)) {
array_map("myfunction",$value);
}
}
}//myfunction close
}
I am trying to put content of one array into the same array. Here I have an array $mclass with values such as
Array
(
[0] => stdClass Object
(
[room_id] => 1,3,5
[day] => 1
[class_teacher] => TEA-2014-2
[final_exam_date] => 2015-09-21
)
)
You can see I have room_id index with 1,3,5 value. Now, I want to explode the room_id and get duplicate of same array index data with change of room_id and push into the array. and finally delete the current array index such as [0]. Here I want the final result as.
Array
(
[0] => stdClass Object
(
[room_id] => 1
[day] => 1
[class_teacher] => TEA-2014-2
[final_exam_date] => 2015-09-21
)
[1] => stdClass Object
(
[room_id] => 3
[day] => 1
[class_teacher] => TEA-2014-2
[final_exam_date] => 2015-09-21
)
[2] => stdClass Object
(
[room_id] => 5
[day] => 1
[class_teacher] => TEA-2014-2
[final_exam_date] => 2015-09-21
)
)
Here is my code for the same:
if(count($mclass)>0)
{
foreach($mclass as $mclasskey=>$mclass_row)
{
/* Room ID Calculation */
if(isset($mclass[$mclasskey]))
{
$temp_room_id = explode(',',$mclass_row->room_id);
if(count($temp_room_id)>1)
{
foreach($temp_room_id as $trkey=>$tr)
{
if(!in_array($temp_room_id[$trkey], $morning_class_semester))
{
array_push($morning_class_semester,$temp_room_id[$trkey]);
}
}
if(count($morning_class_semester)>0)
{
foreach($morning_class_semester as $mcskey=>$mcs)
{
$index_count = count($new_test);
$test[$index_count] = $mclass[$mclasskey];
$test[$index_count]->room_id = $morning_class_semester[$mcskey];
array_push($new_test,$test[$index_count]);
}
unset($mclass[$mclasskey]);
}
}
}
}
}
The code below does what you're looking for using only arrays. So you'll have to change the array access operators to -> since you're accessing an object. I'd do so, but it would break the example, so I'll leave that up to you.
Code Explained:
Loop through array selecting each subarray (object in your case), explode on the $item('room_id') ... ($item->room_id in your case) ... and create sub arrays, via loop, from that using the data from the original using each key. Remove the original item (which has the combined room_ids) and combine the placeholder and original array.
<?php
//Establish some data to work with
$array = array(
array(
"room_id" => "1,3,5",
"day" => 1,
"class_teacher" => "TEA-2014-2",
"final_exam_date" => "2015-09-21",
));
foreach ($array as $key => $item) {
$placeholder = array();
$ids = explode(',',$item['room_id']);
if (count($ids) > 1) {
foreach ($ids as $id) {
$push = array(
'room_id' => $id,
'day' => $item['day'],
'class_teacher' => $item['class_teacher'],
'final_exam_date' => $item['final_exam_date']
);
array_push($placeholder, $push);
}
$array = array_merge($array, $placeholder);
unset($array[$key]);
}
}
var_dump($array);
?>
I have the following multidimensional array:
Array ( [0] => Array
( [id] => 1
[name] => Jonah
[points] => 27 )
[1] => Array
( [id] => 2
[name] => Mark
[points] => 34 )
)
I'm currently using a foreach loop to extract the values from the array:
foreach ($result as $key => $sub)
{
...
}
But I was wondering how do I see whether a value within the array already exists.
So for example if I wanted to add another set to the array, but the id is 1 (so the person is Jonah) and their score is 5, can I add the 5 to the already created array value in id 0 instead of creating a new array value?
So after the loop has finished the array will look like this:
Array ( [0] => Array
( [id] => 1
[name] => Jonah
[points] => 32 )
[1] => Array
( [id] => 2
[name] => Mark
[points] => 34 )
)
What about looping over your array, checking for each item if it's id is the one you're looking for ?
$found = false;
foreach ($your_array as $key => $data) {
if ($data['id'] == $the_id_youre_lloking_for) {
// The item has been found => add the new points to the existing ones
$data['points'] += $the_number_of_points;
$found = true;
break; // no need to loop anymore, as we have found the item => exit the loop
}
}
if ($found === false) {
// The id you were looking for has not been found,
// which means the corresponding item is not already present in your array
// => Add a new item to the array
}
you can first store the array with index equal to the id.
for example :
$arr =Array ( [0] => Array
( [id] => 1
[name] => Jonah
[points] => 27 )
[1] => Array
( [id] => 2
[name] => Mark
[points] => 34 )
);
$new = array();
foreach($arr as $value){
$new[$value['id']] = $value;
}
//So now you can check the array $new for if the key exists already
if(array_key_exists(1, $new)){
$new[1]['points'] = 32;
}
Even though the question is answered, I wanted to post my answer. Might come handy to future viewers. You can create new array from this array with filter then from there you can check if value exist on that array or not. You can follow below code. Sample
$arr = array(
0 =>array(
"id"=> 1,
"name"=> "Bangladesh",
"action"=> "27"
),
1 =>array(
"id"=> 2,
"name"=> "Entertainment",
"action"=> "34"
)
);
$new = array();
foreach($arr as $value){
$new[$value['id']] = $value;
}
if(array_key_exists(1, $new)){
echo $new[1]['id'];
}
else {
echo "aaa";
}
//print_r($new);
So My problem is:
I want to create nested array from string as reference.
My String is "res[0]['links'][0]"
So I want to create array $res['0']['links']['0']
I tried:
$result = "res[0]['links'][0]";
$$result = array("id"=>'1',"class"=>'3');
$result = "res[0]['links'][1]";
$$result = array("id"=>'3',"class"=>'9');
when print_r($res)
I see:
<b>Notice</b>: Undefined variable: res in <b>/home/fanbase/domains/fanbase.sportbase.pl/public_html/index.php</b> on line <b>45</b>
I need to see:
Array
(
[0] => Array
(
[links] => Array
(
[0] => Array
(
[id] => 1
[class] => 3
)
)
)
[1] => Array
(
[links] => Array
(
[0] => Array
(
[id] => 3
[class] => 9
)
)
)
)
Thanks for any help.
So you have a description of an array structure, and something to fill it with. That's doable with something like:
function array_create(&$target, $desc, $fill) {
preg_match_all("/[^\[\]']+/", $desc, $uu);
// unoptimized, always uses strings
foreach ($uu[0] as $sub) {
if (! isset($target[$sub])) {
$target[$sub] = array();
}
$target = & $target[$sub];
}
$target = $fill;
}
array_create( $res, "[0]['links'][0]", array("id"=>'1',"class"=>'3') );
array_create( $res, "[0]['links'][1]", array("id"=>'3',"class"=>'9') );
Note how the array name itself is not part of the structure descriptor. But you could theoretically keep it. Instead call the array_create() function with a $tmp variable, and afterwards extract() it to achieve the desired effect:
array_create($tmp, "res[0][links][0]", array(1,2,3,4,5));
extract($tmp);
Another lazy solution would be to use str_parse after a loop combining the array description with the data array as URL-encoded string.
I have a very stupid way for this, you can try this :-)
Suppose your string is "res[0]['links'][0]" first append $ in this and then put in eval command and it will really rock you. Follow the following example
$tmp = '$'.'res[0]['links'][0]'.'= array()';
eval($tmp);
Now you can use your array $res
100% work around and :-)
`
$res = array();
$res[0]['links'][0] = array("id"=>'1',"class"=>'3');
$res[0]['links'][0] = array("id"=>'3',"class"=>'9');
print_r($res);
but read the comments first and learn about arrays first.
In addition to mario's answer, I used another function from php.net comments, together, to make input array (output from jquery form serializeArray) like this:
[2] => Array
(
[name] => apple[color]
[value] => red
)
[3] => Array
(
[name] => appleSeeds[27][genome]
[value] => 201
)
[4] => Array
(
[name] => appleSeeds[27][age]
[value] => 2 weeks
)
[5] => Array
(
[name] => apple[age]
[value] => 3 weeks
)
[6] => Array
(
[name] => appleSeeds[29][genome]
[value] => 103
)
[7] => Array
(
[name] => appleSeeds[29][age]
[value] => 2.2 weeks
)
into
Array
(
[apple] => Array
(
[color] => red
[age] => 3 weeks
)
[appleSeeds] => Array
(
[27] => Array
(
[genome] => 201
[age] => 2 weeks
)
[29] => Array
(
[genome] => 103
[age] => 2.2 weeks
)
)
)
This allowed to maintain numeric keys, without incremental appending of array_merge. So, I used sequence like this:
function MergeArrays($Arr1, $Arr2) {
foreach($Arr2 as $key => $Value) {
if(array_key_exists($key, $Arr1) && is_array($Value)) {
$Arr1[$key] = MergeArrays($Arr1[$key], $Arr2[$key]);
}
else { $Arr1[$key] = $Value; }
}
return $Arr1;
}
function array_create(&$target, $desc, $fill) {
preg_match_all("/[^\[\]']+/", $desc, $uu);
foreach ($uu[0] as $sub) {
if (! isset($target[$sub])) {
$target[$sub] = array();
}
$target = & $target[$sub];
}
$target = $fill;
}
$input = $_POST['formData'];
$result = array();
foreach ($input as $k => $v) {
$sub = array();
array_create($sub, $v['name'], $v['value']);
$result = MergeArrays($result, $sub);
}
