I have an array of apps with ids and categories like this:
[apps] => Array
(
[0] => stdClass Object
(
[id] => 0
[categoryid] => 0
)
[1] => stdClass Object
(
[id] => 31265
[categoryid] => 12
)
[2] => stdClass Object
(
[id] => 15965
[categoryid] => 2
)
[3] => stdClass Object
(
[id] => 16554
[categoryid] => 12
)
)
I am trying to get all apps for a category based on this request. So, the resultant output for:
For CategoryId 12:
----------------
[apps] => Array
(
[0] => 31265
[1] => 16554
)
For CategoryId 2:
----------------
[apps] => Array
(
[0] => 15965
)
For CategoryId 0:
----------------
[apps] => Array
(
[0] => 0
)
I believe i need to use nested foreach loops, but is there an efficient method?
Thanks
You could cycle through them, and place them into category-arrays:
foreach ( $apps as $app ) {
$catArray[ $app[CategoryID] ][] = $app;
}
This should result in an array whose key represents a category, and whose nested arrays represent those apps in that category.
I've worked up a demo of this online at: http://codepad.org/WZXIvQ58

I have this array $post_types with objects:
Array
(
[vegetables] => WP_Post_Type Object
(
[name] => sports
[label] => Sports
[taxonomies] => Array
(
[0] => country
[1] => type
)
[has_archive] => 1
[show_in_rest] => 1
)
[fruits] => WP_Post_Type Object
(
[name] => fruits
[label] => Fruits
[taxonomies] => Array
(
[0] => color
[1] => taste
[2] => origin
)
[has_archive] => 1
[show_in_rest] => 1
)
)
And I want to prepend the object from array $prepend into it:
Array
(
[post] => WP_Post_Type Object
(
[name] => post
[label] => Post
[taxonomies] => Array
(
[0] => categories
[1] => tags
)
[has_archive] => 1
[show_in_rest] => 1
)
)
I tried the following:
$post_types[] = $prepend
This adds it to the end of the $post_types array and it wraps an array with index 0 around it like so:
[0] => Array
(
[post] => WP_Post_Type Object
...
)
...
I also tried array_unshift($post_types , $prepend);
It adds it to the beginning, but again wraps it in array. How can I add
[post] => WP_Post_Type Object
(
[name] => post
[label] => Post
...
to $post_types without having the [0] => array( ... wrapped around [post] => WP_Post_Type Object ... ?
I also tried array_unshift($post_types, array_column($prepend, 'post')) but adds an empty array.
You should be able to "simply" merge the two arrays:
$post_types = array_merge($prepend, $post_types);
I need to create a db function for multidimensional array. How deep the array currently dont know, bcoz they will come from xml file.
I have a sample array

I need to enter these type of array to db and then retrieve them in a good non programmer readable format
I created 2 table... 1st for array key with array level field and another for key=value
I tried this
function array_Dump($array, $d=1){
if (is_array($array)){
foreach($array as $key=>$val){
for ($i=0;$i<$d;$i++){
$level=$i;
}
if (is_array($val)){
if (is_int($key)){
array_Dump($val, $d+1);
}else{
$query = "insert into xml_array (level, input) VALUES ('$level','$key')";
insert_sql($query);
array_Dump($val, $d+1);
}
} else {
$query = "insert into xml_data (array_id,level_id, array_key,array_value) VALUES ('$insert_id','$level','$key','$val')";
insert_sql($query);
}
}
}
}
Create a table like this:
attributes(id, parent_id, properties)
where id will be the primary key, parent_id will be the id of the parent record and properties will be a small json field with the atomic properties. This way you support any depth the XML may throw towards your direction.
As about non-programmer representation. For instance you could use a table (you can solve that with divs as well) which will contain a row for each element in the top level array. Such a row would contain separate columns for each property. When a property is an array, then the given cell will be a table of its own, which will be handled similarly as the first table. It is advisable to make the inner tables collapsible, so if one wants to see the main levels only, the user will not have to scroll for a long while.
I have these two arrays:
1:
Array
(
[0] => stdClass Object
(
[id] => 1
[name] => Type 1
[rate] => 100.00
)
[1] => stdClass Object
(
[id] => 2
[name] => Type 2
[rate] => 75.00
)
[2] => stdClass Object
(
[id] => 3
[name] => Type 3
[rate] => 50.00
)
[3] => stdClass Object
(
[id] => 4
[name] => Type 4
[rate] => 50.00
)
)
2:
Array
(
[0] => stdClass Object
(
[name] => Type 1
[rate] => 125
)
[1] => stdClass Object
(
[name] => Type 2
[rate] => 85
)
[2] => stdClass Object
(
[name] => Type 3
[rate] => 65
)
)
What I need to do is compare the two arrays, and append missing items from 1st array to the 2nd one. This will always be the case first array will have more items than the second one.
I have tried using something like:
$result = array_udiff($array1,$array2,
function ($obj_a, $obj_b) {
return $obj_a->name - $obj_b->name;
}
);
but it just returns an empty array
This?
<?php
$arr1 = array(
(object)array("id"=>1,"name"=>"type 1","rate"=>100.00),
(object)array("id"=>2,"name"=>"type 2","rate"=>75.00),
(object)array("id"=>3,"name"=>"type 3","rate"=>50.00),
(object)array("id"=>4,"name"=>"type 4","rate"=>50.00)
);
$arr2 = array(
(object)array("name"=>"type 1","rate"=>125),
(object)array("name"=>"type 2","rate"=>85),
(object)array("name"=>"type 3","rate"=>65)
);
for($i=0;$i<sizeof($arr1);$i++){
$count=0;
for($j=0;$j<sizeof($arr2);$j++){
if($arr1[$i]->name == $arr2[$j]->name){
$count++;
}
}
if($count==0){
array_push($arr2,(object)array("name"=>$arr1[$i]->name,"rate"=>$arr1[$i]->rate));
}
}
print_r($arr2);
?>
Doesn't need to be complicated, assuming that you allow the arrays to contain objects of the same type and structure. We don't have enough context given the question to understand whether there is a good reason you can't.
//$array1 original array
//$array2 target array
$array2 = array_merge($array1, $array2);
I tried to get an answer for this in other posts with no luck, hope someone can help me here, i have a multidimensional array:
Array (
[0] => stdClass Object (
[affectsVersions] => Array ( )
[assignee] => hmontes
[attachmentNames] => Array ( )
[components] => Array ( )
[created] => 2012-08-15T05:31:26.000Z
[customFieldValues] => Array (
[0] => stdClass Object (
[customfieldId] => customfield_10201
[key] => [values] => Array (
[0] => 123456
)
)
[1] => stdClass Object (
[customfieldId] => customfield_10004
[key] => [values] => Array (
[0] => 30
)
)
)
[description] => [duedate] => [environment] => [fixVersions] => Array ( )
[id] => 10228
[key] => NTP-29
[priority] => 3
[project] => NTP
[reporter] => hmontes
[resolution] => [status] => 1
[summary] => case 123456
[type] => 3
[updated] => 2012-08-15T05:31:26.000Z
[votes] => 0
)
)
this is what i get when i do a print_r with the array variable, i need to search and get the value from [key] that would be in this case NTP-29 and keep it in a variable as string.
You can get the value of an array by the key using $array['keyName'];
But, for you it looks like you just need to go deeper $array[0]['key'];
Both arrays values and properties of objects can be accessed using associative array syntax. To get the value of the key property in your object within the array you'd do the following, assuming $array is a variable containing a reference to your array:
$key = $array[0]['key']; // accesses NTP-29 in this case.
Here's another way to access the same property, using object property-access syntax:
$key = $array[0]->key; // also accesses NTP-29.
I'm racking my brains trying to think of a solution. I can find plenty of solutions to remove dupes from a 2d array but I need to remove dupes where a value is lower than the other. Here is the array:
Array
(
[basketball] => Array
(
[0] => stdClass Object
(
[id] => 2
[username] => Beans
[points] => 30
)
[1] => stdClass Object
(
[id] => 314
[username] => slights
[points] => 20
)
[2] => stdClass Object
(
[id] => 123
[username] => gibb54
[points] => 5
)
)
[soccer] => Array
(
[0] => stdClass Object
(
[id] => 2
[username] => Beans
[points] => 95
)
[1] => stdClass Object
(
[id] => 49
[username] => sans
[points] => 65
)
[2] => stdClass Object
(
[id] => 122
[username] => peano
[points] => 50
)
[3] => stdClass Object
(
[id] => 174
[username] => fordb
[points] => 30
)
[4] => stdClass Object
(
[id] => 112
[username] => danc
[points] => 30
)
)
)
As you may see, user ID 2, Beans is the first selection for both basketball and soccer. As they have more points for soccer, I need to remove their entry for basketball to make ID 314, slights the 0 value.
I would need to do this continually until no user be the 0 value for any of the primary array values twice.
I've tried various combinations of foreach solutions but I'm not getting anywhere. I thought a while loop would be more suitable but I don't know what condition to test for.
Any ideas please?!
I would loop through your data and create a dictionary where the keys are the user ids, and the values are the appropriate user objects with the sport appended. Then you can reconstruct your example data array structure by looping through this de-duped array using the sport data to determine where to put each user.
To create the de-duped array, use something like:
$deDupedData = array();
foreach ($data as $sport => $users) {
foreach ($users as $user) {
if (isset($deDupedData[$user->id])) {
if ($user->points > $deDupedData[$user->id]->points) {
$deDupedData[$user->id]->sport = $sport;
$deDupedData[$user->id]->points = $user->points;
}
} else {
$modifiedUser = $user;
$modifiedUser->sport = $sport;
$deDupedData[$user->id] = $modifiedUser;
}
}
}
// Now reconstruct your array...
