   Here is an example for string:

   echo urlencode_deep( 'foo bar' );
   
   // Output will be: foo+bar

   Here is an example for array:

   $data = urlencode_deep( array( 'foo' => 'bar long text', 'key1' => 'value1' ) );
   
   // Output will be for $data: array( 'foo' => 'bar+long+text', 'key1' => 'value1' )

   Here is a use case for multi word string as url parameter:

   echo add_query_arg( 'key', urlencode_deep( 'long value' ), 'http://example.com/' );
   
   // Output will be: http://example.com/?key=long+value

   Here is a use case for an array multi word string as url parameter:

   $params = array( 
       'key1' => 'value1 long text',
       'key2' => 'value2',
   );
   
   echo add_query_arg(
       urlencode_deep( $params ),
       'http://example.com/?'
   );
   
   // Output will be: http://example.com/?key1=value1+long+text&key2=value2

   It’s making spaces between word, if string has space:

   echo add_query_arg( 'key', 'long value', 'http://example.com/' );
   
   // Output will be: http://example.com/?key=long value
