How to convert the color in which array %23dd3333 to #dd3333 format?

Question

1C-Bitrix

did so, but it's a function for url not for string echo urldecode(esc_attr( $font_container )), right?

Answer 1

Why not for a string? Here is an example:

$a = '%23dd3333';
$b = urldecode($a);

echo $b;

For the future: try to punctuate and describe your problem in more detail. What array? What's inside this array. There are no psychics here.
