Echo a multidimensional array in PHP

Question

I have a multidimensional array and I\'m trying to find out how to simply \"echo\" the elements of the array. The depth of the array is not known, so it could be deeply nest

Answer 1

Proper, Better, and Clean Solution:

function traverseArray($array)
{
    // Loops through each element. If element again is array, function is recalled. If not, result is echoed.
    foreach ($array as $key => $value)
    {
        if (is_array($value))
        {
            Self::traverseArray($value); // Or
            // traverseArray($value);
        }
        else
        {
            echo $key . " = " . $value . "
\n";
        }
    }
}

You simply call in this helper function traverseArray($array) in your current/main class like this:

$this->traverseArray($dataArray); // Or
// traverseArray($dataArray);
