PHP. Is array_map faster than foreach?

In terms of performance, is this the best option?

While in the object:

Case number 1

public function test( $array ) {
    return array_map( array( $this, 'do_something_to_element' ), $array );
}

      

        
        
        
      

    

Case number 2

public function test( $array ) {
    $return = array();
    foreach ( $array as $value ) {
        $return[] = do_something_to_element( $value );
    }
    return $return;
}

      

        
        
        
      

    

There are other options, of course, and many examples can be filled in. I saw comments that array_map is slower than foreach.

Are array_map / array_walk functions generally faster than foreach loops with similar needs?
