php - Executing calling class' method -

- 

class car {     $gas= new gas();     $gas->fill( 'filledhandler' );      function filledhandler()     {         echo 'gas has been filled!';     } }  class gas {     function fill( $function )     {         // here         $function();      } }

i need call $function of calling class. right now, it's looking global function

you have pass calling instance.

class car {     function fillgas()     {         $gas = new gas();         $gas->fill($this, 'filledhandler');     }      function filledhandler()     {         echo 'gas has been filled!';     } }  class gas {     function fill($obj, $function)     {         // if need class name, use get_class($obj)         $obj->$function();     } }

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
