Question

Not sure if this is possible but here goes… i need to get all of the indexes of an array contained within an object

foreach

<?php foreach($all_orders as $key => $val) : ?>

<?php 
    $cart = unserialize($val->cart);  
    $keys = array_keys($cart); 
    $x = count($keys); 
    $index = $keys[$x]; 
    $cart = $cart[$index]; 
?>

<?php $val->field_name; ?>

<?php endforeach; ?>

var_dump

array (size=3)

This code is contained inside of a foreach The var $cart contains an object of an ARRAY with multiple indexes. If I replace $x with 0 the loop will display the first index in the cart array. However some cart contain more than > 1 index.

count($keys) is properly echoing out the number of indexes in the cart array. For example I have 3 carts.

1. cart 1 has 1 index
2. cart 2 has 2 index
3. cart 3 has 4 index

If i do echo count($keys) I get back 1 2 4

How do I pass these values (in order) individually to my $x var for each loop?

Notice how cart may have more than 1 index value

Expect Output:

Each cartcontains an array with multiple products. The foreach must iterate through and display each product in the array within cart Based on the var_dump shown above the expected output of the cart array should be in a table as follows:

<tr>0</tr> /*cart 1 has 1 index in the array*/
<tr>01</tr> /*cart 2 has 2 index in the array*/
<tr>0123</tr> /*cart 3 has 4 index in the array*/

Answer 1

You can give try as below

You have each order can have multiple carts and each cart have multiple items.What you want to display # of items into each cart.

<?php 
    $cart = unserialize($val->cart);  
    $keys = array_keys($cart); // this will give you # of carts into one order
    //if now you want to count # of items into each cart then
    foreach($keys as $val){
      echo count($cart[$val]);
    }

?>
