Get Every Key & Value from Array then Display All in New Line

Question

I'm trying to display every key and value from WooCommerce get_formatted_meta_data order meta details. This is my code to generate the array:

$order = new WC_Order( $order_id );
    foreach ( $order->get_items() as $item_id => $item ) {
        $item_data = $item->get_data();
        $item_meta_data = $item->get_meta_data();
        $formatted_meta_data = $item->get_formatted_meta_data( ' ', true );
        $array = json_decode(json_encode($formatted_meta_data), true);
        $arrayx = array_values($array);
            foreach($arrayx as $value) {
                $result[]=array($value["display_key"], wp_strip_all_tags($value["display_value"]));
                foreach ($result as $key => $value) {
                    $var_label = $key;
                    $var_value = $value;
                    }
                }
    }

And this is the array I managed to print using above function:

Array
(
    [0] => Array
        (
            [0] => Color
            [1] => Black
        )

    [1] => Array
        (
            [0] => Size
            [1] => M
        )

    [2] => Array
        (
            [0] => Gift
            [1] => Tes 2
        )

)

Now I want to get each value in the array and want to display them like this (displayed in new line):

Color: Black
Size: M
Gift: Tes 2
etc
etc
etc (dynamically inserted by WooCommerce if any or added by other plugins)

This is what I have already tried:

$order = new WC_Order( $order_id );
foreach ( $order->get_items() as $item_id => $item ) {
    $product_id   = $item->get_product_id();
    $quantity     = $item->get_quantity();
    $product_name = $item->get_name();
    $item_data = $item->get_data();
    $item_meta_data = $item->get_meta_data();
    $formatted_meta_data = $item->get_formatted_meta_data( ' ', true );
    $array = json_decode(json_encode($formatted_meta_data), true);

    $arrayx = array_values($array);
    $count=0;
    foreach($arrayx as $value) {
        $result[]=array($value["display_key"], wp_strip_all_tags($value["display_value"]));
        foreach ($result as $key => $value) {
            $var_label = $key;
            $var_value = $value;
            $metadata['count'] = "\r\n".$var_label[0].": ".$var_value[0]."";
            $count++;
        }
    }
           
    $formatted_product_name = wp_strip_all_tags(" *".$product_name."*");
    $product_plus_meta = "*".$formatted_product_name."* ".$metadata['count']."";
    $quantity = $item->get_quantity();
    $output_content.= urlencode("".$quantity."x - ".$product_plus_meta."\r\n");
   }
}
$output_content.="".$price."";

Using the above code, I could only fetch one value and key from the array (only the latest in the array) which is Gift => Tes 2. And the output is something like this:

1x - **Sample Product** 
Gift: Tes 2

Price: $12.00

Instead of this:

1x - **Sample Product**
Color: Black
Size: M
Gift: Tes 2

Price: $12.00

How to get the full list of each existed array key and value and display all of them in new line like above sample?

Thank you very much in advance. Any help would be much appreciated.

Answer 1

if you can print your array why cant' you just do a loop on this array and adding each line into your output_content. It will look like this

<?php
$myArray = Array
(
    0 => Array
        (
            0 => "Color",
            1 => "Black",
        ),

    1 => Array
        (
            0 => "Size",
            1 => "M",
        ),

    2 => Array
        (
            0 => "Gift",
            1 => "Tes 2"
        ),

);
$output_content = "";
foreach($myArray as $key){
    $output_content .= $key[0]." : ".$key[1]."\r";
}
echo $output_content;

?>

And this code prints :

Color : Black
Size : M
Gift : Tes 2

Answer 2

By using @Djilan's answer, I managed to fetch the data accordingly and tweak how it will be displayed, preventing compounded array in the next item.

I missed this part (answered by @Djilan), and this is indeed the correct way:

$product_meta = "";
foreach($myArray as $key){
    $product_meta .= $key[0]." : ".$key[1]."\r";
}
echo $product_meta ;

Just need to adjust the code, and this is the final code:

...
...
$order = new WC_Order( $order_id );
foreach ( $order->get_items() as $item_id => $item ) {
    $product_id   = $item->get_product_id(); //Get the product ID
    $quantity     = $item->get_quantity(); //Get the product QTY
    $product_name = $item->get_name(); //Get the product NAME
    $quantity = $item->get_quantity();
    $output_content .= urlencode("".$quantity."x - *".$product_name."*\r\n");
        // get order item data
        $item_data = $item->get_data();

        // get order item meta data
        $item_meta_data = $item->get_meta_data();

        // get only All item meta data
        $formatted_meta_data = $item->get_formatted_meta_data( '_', true );
        $array = json_decode(json_encode($formatted_meta_data), true);
        $arrayx = array_values($array);
        $arrayxxx = array_merge($array);
        $result = array();
    foreach( (array) $arrayxxx as $value) {
        $product_meta = "";
        $result[]=array($value["display_key"], wp_strip_all_tags($value["display_value"]));
        foreach ($result as $key) {
            $result = array();
            $product_meta .= "     - ".$key[0].": ".$key[1]."\r\n";
            $output_content.= urlencode("".$product_meta."");
       }
    }
}
$output_content.="".$format_subtotal_price."";
echo $output_content;

And the final output would be something like this:

1x - Sample Product #1 - Black, M
     - Color: Black
     - Size: M
1x - Sample Product #2
     - Color: Blue
     - Size: XL
     - Gift: Tes 3
