I have a string with the following format:

$data = "sku=32300905,color=Dark Brown|sku=32300899,color=Blue|sku=32300900,color=Grey|sku=32300914,color=light Brown";

And I want to transform this string into an array of associative arrays as shown below:

Array
(
    [0] => Array
        (
            [sku] => 32300905
            [color] => Dark Brown
        )

    [1] => Array
        (
            [sku] => 32300899
            [color] => Blue
        )

    [2] => Array
        (
            [sku] => 32300900
            [color] => 
        )

    [3] => Array
        (
            [sku] => 32300914
            [color] => light Brown
        )

    [4] => Array
        (
            [sku] => 12345678
            [color] => 
        )

)

What would be the most efficient way to achieve this conversion in PHP?

>Solution :

You can try this way to get you response

$data = "sku=32300905,color=Dark Brown|sku=32300899,color=Blue|sku=32300900,color=Grey|sku=32300914,color=light Brown";

$convertToArray = explode('|', $data);
$result = array_map(function ($pair) {

    list($key, $value) = explode(',', $pair);
    return array_combine(explode('=', $key), explode('=', $value));

}, $convertToArray);

echo '<pre>';
print_r($result);
echo '</pre>';

Or you can also do like this

$convertToArray = explode('|', $data);
        
        $result = array_map(function ($item) {
            $sku = null;
            $color = null;
        
            $newArray = explode(',', $item);
            // print_r($newArray);
            
            foreach ($newArray as $field) {
                $parts = explode('=', $field);
                if ($parts[0] === 'sku') {
                    $sku = $parts[1];
                } elseif ($parts[0] === 'color') {
                    $color = $parts[1];
                }
            }
        
            return ['sku' => $sku, 'color' => $color];
        }, $convertToArray);
        
                

                echo '<pre>';
                print_r($result);
                echo '</pre>';
