function HeaderUtils::toString

Joins an associative array into a string for use in an HTTP header.

The key and value of each entry are joined with '=', and all entries are joined with the specified separator and an additional space (for readability). Values are quoted if necessary.

Example:

HeaderUtils::toString(['foo' => 'abc', 'bar' => true, 'baz' => 'a b c'], ',') // => 'foo=abc, bar, baz="a b c"'
