Fastest way to implode an associative array with keys

Question

I\'m looking for a fast way to turn an associative array in to a string. Typical structure would be like a URL query string but with customizable separators so I can use \'<

Answer 1

This is my solution for example for an div data-attributes:

 'http://example.com',
    'data-width'  => '300',
    'data-height' => '250',
    'data-type'   => 'cover',
);

$dataAttributes = array_map(function($value, $key) {
    return $key.'="'.$value.'"';
}, array_values($attributes), array_keys($attributes));

$dataAttributes = implode(' ', $dataAttributes);

?>
