create multidimensional array using a foreach loop
You're aaalmost there. Just add the level to the array creation :)
$levels = array('low', 'medium', 'high');
$attributes = array('fat', 'quantity', 'ratio', 'label');
foreach ($levels as $key => $level):
foreach ($attributes as $k =>$attribute):
$variables[$level][] = $attribute . '_' . $level; // changed $variables[] to $variables[$level][]
endforeach;
endforeach;
echo '<pre>' . print_r($levels,1) . '</pre>';
echo '<pre>' . print_r($variables,1) . '</pre>';
Array
(
[low] => Array
(
[0] => fat_low
[1] => quantity_low
[2] => ratio_low
[3] => label_low
)
[medium] => Array
(
[0] => fat_medium
[1] => quantity_medium
[2] => ratio_medium
[3] => label_medium
)
[high] => Array
(
[0] => fat_high
[1] => quantity_high
[2] => ratio_high
[3] => label_high
)
)
how to create multidimensional array using a foreach loop in php?
My guess is your foreach loop looks like this:
$result = array();
foreach($members as $member) {
$result['firstname'][] = $member['firstname'];
$result['last_name'][] = $member['last_name'];
//etc
}
$result = array();
foreach($members as $member) {
$result[] = array(
'firstname' => $member['firstname'],
'last_name' => $member['last_name'],
'job' => $member['job'],
'desc' => $member['desc'],
'image_url' => $member['image_url']
);
}
The POST fields are arrays, so you have to make sure all fields are posted for every member, as the for loop is based on all fields having the same amount of values.
$fname = $_POST['first_name'];
$lname = $_POST['last_name'];
$job = $_POST['job'];
$desc = $_POST['desc'];
$photo = $_POST['image_url'];
$memberdata = array();
// we iterate the firstname field and access the same indexes from the other fields. The $i starts with 0 and gets incremented until it iterated over all the firstnames
for($i = 0; $i < count($fname); $i++) {
$memberdata[] = array(
'first_name' => $fname[$i], // we access the firstname at the current index
'last_name' => $lname[$i],
'job' => $job[$i],
'desc' => $desc[$i],
'image_url' => $photo[$i]
);
}
var_dump($memberdata);
Multidimensional array in PHP using foreach loop
Use the following, Tested and working
$filterArray = array();
$i = 0;
foreach($salary as $dept => $employee){
foreach($employee as $index => $data){
if($data['salary'] > 10000){
$filterArray[$i]['deprtment'] = $dept;
$filterArray[$i]['name'] = $data['name'];
$filterArray[$i]['salary'] = $data['salary'];
}
$i++;
}
}
Array
(
[1] => Array
(
[deprtment] => PHP
[name] => Raj
[salary] => 15000
)
[2] => Array
(
[deprtment] => PHP
[name] => Mihir
[salary] => 12000
)
[3] => Array
(
[deprtment] => Flex
[name] => Vijay
[salary] => 14000
)
)

How does foreach loop works with 2d array?
2D string array is not optimal choice for your task ("build a store with car"). c# is object-oriented language, so you can have a class for Car, and a class for Store with list of cars - easy to build, maintain, modify:
public class Car
{
public string Brand { get; set; }
public double Price { get; set; }
public int Year { get; set; } // new Car property
}
public class CarStore
{
public IList<Car> Cars { get; } = new List<Car>();
}
for loop or foreach - both will workpublic static void Main()
{
var store = new CarStore
{
Cars =
{
new Car { Brand = "Ford", Year = 2021, Price = 120000 },
new Car { Brand = "Chevrolet", Year = 2020, Price = 100000 },
}
};
foreach(var car in store.Cars)
{
Console.WriteLine(car.Price.ToString("C"));
}
// new car arrived:
store.Cars.Add(new Car { Brand = "Rolls-Royce", Year = 2022, Price = 1_000_000 });
}
php - How to insert a foreach loop inside a multidimensional array
I want say thank you to @adrianRosi for the help and the input he gives me.
In the end I find my solution, that it's json_encode the array before add into $data in json format.
in this way:
$product_list = [];
foreach ($order->pad_products as $product) {
$product_list[] = array(
"id" => "$id",
"..." => "...",
);
};
$data_products['lines'] = $product_list;
$json_products = json_encode($data_products);
$json_products_edit = substr($json_products, 1, -1); // to delete the {}
$prezzo_totale = $order->pad_price_total;
$json_data = '{
...
...
'.$json_products_edit.'
}';
php: How to foreach a multidimensional array?
The array you're trying to iterate with your foreach loop is not the same as the array you have. In order to use that loop, your array would need to be like this instead:
[
[
'work_time' => 0.00,
'break_time' => 0.00,
'meeting_time' => 0.00,
'login_time' => '10:11',
'logout_time' => '00:00',
'work_date' => '2018-04-13'
],
[
'work_time' => 3.96,
'break_time' => 0.00,
'meeting_time' => 0.00,
'login_time' => '08:48',
'logout_time' => '13:00',
'work_date' => '2018-04-16'
],
[
'work_time' => 7.75,
'break_time' => 1.06,
'meeting_time' => 0.00,
'login_time' => '09:09',
'logout_time' => '17:59',
'work_date' => '2018-04-17'
],
];
<input type="text" name="work[work_time][]">
<input type="text" name="work[0][work_time]">
On the other hand, with the array you have, you can just iterate one of the inner arrays directly. For example, if you wanted to show login_time values, it's just
foreach ($Work['login_time'] as $login_time) {
echo $login_time;
}
foreach ($Work['login_time'] as $key => $login_time) {
echo 'login time: ' . $login_time . ', work_date: ' . $Work['work_date'][$key];
}
Print Multi-dimensional array using loop in PHP
you have associative array inside associative array
You have to loop the first associative array
and inside it loop the associative array
like this
foreach($bazar as $key => $val){
echo $key.'<br>';
foreach($val as $k => $v){
echo $k . ' -> ' .$v . '<br>';
}
}
