How to loop a foreach on an object/array

Question

My DB returns an array of objects with arrays within.

Var_dump

array (size=2)
  0 => 
    object(stdClass)[22]
      public 'customer_id' => string '10' (length=2)
      public 'cart' => string 'a:1:{s:32:"f9bb1d342b1c2a0bfe982ef405369ec0";a:9:{s:5:"rowid";s:32:"f9bb1d342b1c2a0bfe982ef405369ec0";s:2:"id";s:9:"101_30524";s:3:"qty";s:1:"1";s:5:"price";s:5:"104.5";s:4:"name";s:13:"Business Card";s:5:"image";s:18:"business-cards.gif";s:4:"ship";a:3:{s:6:"Ground";d:9.730000000000000426325641456060111522674560546875;s:11:"2nd Day Air";d:18.53999999999999914734871708787977695465087890625;s:9:"Overnight";d:26.269999999999999573674358543939888477325439453125;}s:7:"options";a:2:{s:17:"Print Description";s:16'...

      public 'timestamp' => string '2012-10-12 20:29:10' (length=19)

Notice cart is a multidimensional array. How do I loop through these objects and arrays and create a table?

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

    <?php echo $key; ?>  <?php echo $val; ?>

<?php endforeach; ?>

This causes the following error: A PHP Error was encountered Severity: 4096 Message: Object of class stdClass could not be converted to string

Access the properties of the stdClass object using the -> operator:

<?php foreach($all_orders as $key => $val) : ?>
Customer ID <?php echo $val->customer_id ?> has a total of <?php echo $val->order_total ?><br />
<?php endforeach ?>

Hey that works great ... except how to echo out cart? Cart is a serialized array. <?php echo unserialize($val->cart); ?> It throws an error * Array to string conversion *

drew010 Over a year ago

It looks like you would have to do something like: $cart = unserialize($val->cart); $key = array_keys($cart)[0]; // PHP 5.4+ echo $cart[$key]['price'];

drew010 Over a year ago

Reason being it appears the cart array is keyed by a hash code so you can't do $cart[0]

MrPizzaFace Over a year ago

That's causing Undefined offset: 0 error and the following: ` $key = array_keys($cart)[0];` causes a SYNTAX error

Ok check this out if i do echo $cart['f9bb1d342b1c2a0bfe982ef405369ec0']['price']; I get the right output. So $key is not passing the right index So how do I get the correct index from the foreach loop? thanks for your help btw! :)

You can try

echo "<pre>";
foreach ( $cart as  $all_orders ) {
    foreach ( $all_orders as $key => $value ) {
        echo $key, " = ", $value, PHP_EOL;
    }
}

PHP 5 allows one to iterate over an object's public properties using a foreach loop.

For more information (and code examples): http://php.net/manual/en/language.oop5.iterations.php

I use PHP's ArrayObject in my MVC:
us3.php.net/manual/en/class.arrayobject.php

        $arrayobject = new ArrayObject($dataRows);
        for ($iterator = $arrayobject->getIterator(); $iterator->valid(); $iterator->next()) {

        }
