Multidimensional Array to String

Question

I am trying to convert a multidimensional array into a string with a particular format.

function convert_multi_array($array) {
    foreach($array as $value)          


        

Answer 1

Saving the imploded inner arrays to an array. Then imploding those.

(written in the spirit of your original implementation)

function convert_multi_array($arrays)
{
    $imploded = array();
    foreach($arrays as $array) {
        $imploded[] = implode('~', $array);
    }
    return implode("&", $imploded);
}
