I have a multidimensional array that is displayed to users in a table, where they can select items by a checkbox.
When they've checked their items and submit, I've now got an array of id values that correspond to the myid key of the original sub arrays.
How can I search the original array and create a new array of only the matching selected items?
Array (
[0] => Array (
[myid] => 22
[Price] => Some price
[Title] => Some text
)
[1] => Array (
[myid] => 36
[Price] => Some price
[Title] => Some text
)
)
Any help would be greatly appreciated!
Simple way but can be optimized
<?php
$submittedVaule = array('12','14');
$subArray = array(0 => array('myid' => 12,'price' => '100','title' => 'test1'),1 => array('myid' => 13,'price' => '100','title' => 'test2'),2 => array('myid' => 14,'price' => '100','title' => 'test3'));
$finalarray = array();
foreach($subArray as $key=>$value){
if(in_array($value['myid'], $submittedVaule )) {
$finalarray[]=$subArray[$key];
}
}
print_r($finalarray);
?>

I have a multi dimensional array with some values coming from a foreach, i need to insert this values into the array, but at this moment my result is this, not sure why:
Array
(
[0] => Array
(
[title] => MySecure
)
[1] => Array
(
[productTitle] => My New Product
)
[2] => Array
(
[title] => My Second Company
)
[3] => Array
(
[productTitle] => Another Product
)
[4] => Array
(
[productTitle] => Away Product
)
)
This is wrong, what i need is:
Array
(
[0] => Array
(
[title] => MySecure
[productTitle] => My New Product
)
[2] => Array
(
[title] => My Second Company
[productTitle] => Another Product
[productTitle] => Away Product
)
)
So this is what i have done:
$companies[] = [
'title' => $getCompanie->getTitle()
];
Then inside products :
$companies[] = [
'productTitle' => $getProduct->getTitle(),
];
so i assume im using the wrong array call, not sure about array_push?
You need to add both keys in the same inner array, rather than pushing them separately.
Use nested loops to get all the products associated with a company in the same loop.
$companies = [];
foreach ($all_companies as $companie) {
$products = [];
foreach ($companie->getProducts() as $getProduct) {
$products[] = $getProduct->getTitle());
}
$companies[] = [
'title' => $companie->getTitle(),
'productTitle' => $products
]
}
I've had to make up names for some of the things I assumed are in your code. You should be able to extrapolate from this to your actual design.
$newArray= [
'title' => array_map($yourArray,fn($ar)=>$ar['title']),
'productTitle' => array_map($yourArray,fn($ar)=>$ar['productTitle'])
];
I have an array which is as follows:
Array
(
[0] => Array
(
[postId] => 105
[postTitle] => Test
[postNonArray] => Subzero
[postDesc] => Array
(
[0] => Array
(
[para] => Subzero
[align] => L
)
)
[postDate] => 25.08.2016
[postTime] => 13:44
[postImage] => http://testyourprojects.biz/custom/ci/tharjumal/uploads/post/post_1472112857.png
[postVideo] =>
)
[1] => Array
(
[postId] => 106
[postTitle] => Test 2
[postNonArray] => Test
[postDesc] => Array
(
[0] => Array
(
[para] => Test
[align] => L
)
)
[postDate] => 26.08.2016
[postTime] => 18:08
[postImage] => http://testyourprojects.biz/custom/ci/tharjumal/uploads/post/post_1472215085.jpg
[postVideo] =>
)
[2] => Array
(
[postId] => 106
[postTitle] => Test 2
[postNonArray] => Test
[postDesc] => Array
(
[0] => Array
(
[para] => Test
[align] => L
)
)
[postDate] => 26.08.2016
[postTime] => 18:08
[postImage] => http://testyourprojects.biz/custom/ci/tharjumal/uploads/post/post_1472215085.jpg
[postVideo] =>
)
)
As you can see, there is two post details with postId=106;
How can I remove the redundant data from the array based on postId?
The project is on PHP.
I think this is what you are trying to achieve:-
$array = array_map("unserialize", array_unique(array_map("serialize", $array)));
echo "<pre/>";print_r($array);
Check output(whole code with your original array):- https://eval.in/630678
Note:- It will remove the duplicate values (so whole duplicate array will gone as you asked in comment)
I would suggest loop like the one below. It will go through all the elements from $your_array_name and will make an unique array of id where we will store the postIds. We will also check if there are duplicated in the $unique_ids array, and if so we will remove that duplicate element.
$unique_ids = array();
foreach($your_array_name as $key => $value){
//check if the postId is in the array of the unique ids
if(!in_array($value['postId'], $unique_ids)()){
array_push($unique_ids,$value['postId']); //if it is not - push it there
} else {
unset($your_array_name($key)); //if it is - remove the whole element from the array
}
}
You will need to loop the data and create a new array with unique values so here you go:
$ShowNewArray = array();
foreach($array as $key => $value){
if(!array_key_exists('postId', $ShowNewArray)){
$ShowNewArray[$value['postId']] = $value;
}
}
print_r($ShowNewArray);
Hope it will help you.
Trying to learn multidimensional arrays but seem to constantly struggle with accessing them. I still have not got grasps of how you access them using index, keys, values.
How do I get to the actual word "Title" and it's value?
Here I have one I was playing with.
$shop = array( array( "Title" => "rose",
"Price" => 1.25,
"Number" => 15
),
array( "Title" => "daisy",
"Price" => 0.75,
"Number" => 25,
),
array( "Title" => "orchid",
"Price" => 1.15,
"Number" => 7
)
);
Which prints a structure such as this:
Array
(
[0] => Array
(
[Title] => rose
[Price] => 1.25
[Number] => 15
)
[1] => Array
(
[Title] => daisy
[Price] => 0.75
[Number] => 25
)
[2] => Array
(
[Title] => orchid
[Price] => 1.15
[Number] => 7
)
)
echo $shop[0][0][0]; //I Expect "rose" but I get "Undefined offset: 0"
echo $shop['Price']; //I expect 1.25 but I get "Undefined index: Price"
foreach($shop as $key=>$value)
{
echo $key; //I expect the key values "Title/Price/Number" instead I get Index numbers 0 1 2
echo $value; //I expect all values of keys e.g. "rose",1.25,15/"daisy",0.75,25/"orchid",1.15,7 Instead I get Array to string conversion error
}
What I am trying to do, is take all the title and value from the shop array, and put it into a new array called $x = array(); and then take a car key/value from a different array and combine them together.
so the new array ends up looking like this:
Array
(
[0] => Array
(
[Title] => rose //from $shop array
[Car] => Mercedez //from $car array
)
[1] => Array
(
[Title] => daisy //from $shop array
[Car] => Ford //from $car array
)
[2] => Array
(
[Title] => orchid //from $shop array
[Car] => Bentley //from $car array
)
)
Also is there a way to access the actual name of the key "title" and not a index number?
You have an array of arrays, therefore you'll need two loops.
foreach ($shop as $item) {
foreach ($item as $key => $value) {
echo $key;
echo $value;
}
}
Try this -
$newarray = array();
foreach($shop as $key=>$value) {
$newarray[$key]['Title'] = $value['Title'];
$newarray[$key]['Number'] = $value['Number'];
}
echo "<pre>";print_r($newarray);
Here, $newarray will give you output like this.
Array
(
[0] => Array
(
[Title] => rose
[Number] => 15
)
[1] => Array
(
[Title] => daisy
[Number] => 25
)
[2] => Array
(
[Title] => orchid
[Number] => 7
)
)
You could access by $shop[0]['Title']
0 means the first item in array and this item is also an array, which contains string keys so 'title' as second level.
To iterate it use:
//Syntax array as key => value (value is in this case also an array)
foreach($shop as $iterator_level1 => $shop_set){
//so you can access the 2. level by string key.
echo $shop_set['title'];
}
Hope this is helpful.
I am working on a php project. I am stuck at this point.
Here is the array that I have.
[text_numeric] => Array
(
[text] => Numeric field fillable by user
[parameters] => Array
(
[prefix] => 1
[price] => 1
[sku] =>
[quantity] =>
[weight] =>
[min_value] => 1
[max_value] => 1
)
[operand] => Array
(
[op_fix_discount] => 1
[op_fix_recharge] => 1
[op_per_unit] => 1
[op_percentage] =>
)
)
[checkbox] => Array
(
[text] => Checkbox attributes
[parameters] => Array
(
[prefix] => 1
[price] => 1
[sku] => 1
[quantity] => 1
[weight] => 1
[min_value] =>
[max_value] =>
)
[operand] => Array
(
[op_fix_discount] => 1
[op_fix_recharge] => 1
[op_per_unit] =>
[op_percentage] => 1
)
)
I want to get all the values from this array with key value "text" in another array.
Like this:
Array
(
[0]=>Numeric field fillable by user
[1]=>Checkbox attributes
)
It could have been great if you had show us your efforts to achieve that but since you are new here is the codez. You can simply get it using a foreach loop,
$new_array = array();
foreach($your_array as $k=>$row){
$new_array[$k] = $row['text'];
}
print_r($new_array);
You can also use array_map,
function getTextField($a) {
return $a['text'];
}
$texts = array_map('getTextField', $your_array);
print_r($texts);
I have the below array, that needs some additional structuring.
Array
(
[-Others] => Array
(
[0] => Array
(
[products_sold] => 1
[products_total_sales] => 2.99
[products_total_costs] => 1.75
[products_total_profit] => 1.24
)
[1] => Array
(
[products_sold] => 1
[products_total_sales] => 2.3322
[products_total_costs] => 1.75
[products_total_profit] => 0.5822
)
)
[Addict] => Array
(
[0] => Array
(
[products_sold] => 1
[products_total_sales] => 35.1
[products_total_costs] => 40
[products_total_profit] => -4.9
)
I have truncated this early, obviously. I was wondering if it would be possible to add up all the sales for all child products, the products_total_sales per brand (aka addict)
I would like to get it in before they are parsed so something like:
[Addict] => Array
(
[0] => Array
[brand_total_sales] => '$value'
(
[products_sold] => 1
...
Any help is greatly appreciated. Thanks in advance and feel free to ask if you need more information
Well, in case the answer is yes:
foreach($array as $brand_name => $brand_array) {
$array[$brand_name]['brand_total_sales'] = 0;
foreach($brand_array as $product) {
$array[$brand_name]['brand_total_sales'] += $product['products_total_sales'];
}
}
