Converting code with Anonymous functions to PHP 5.2

Question

I have some PHP 5.3 code which builds an array to be passed to a view. This is the code I have.

# Select all this users links.
$data = $this->link_model-&

You could call one of those function like so:

$func = $callbacks[0];
$func();

Which also works with create_function() and using strings for named functions like so:

function test() {
  echo "test";
}
$func = 'test';
$func();

$func = create_function('' , 'echo "test 2"; ');
$func();

Also, if the calling is done using call_user_func you can use array($object, 'func_name') to call a public method on an object or a class with array('Class_Name', 'func_name'):

class Test {
  public static function staticTest() { echo "Static Test"; }
  public function methodTest() { echo "Test"; }

  public function runTests() {
    $test = array('Test', 'staticTest');
    call_user_func($test);

    $test = array($this, 'methodTest');
    call_user_func($test);
  }
}

$test = new Test();
$test->runTests();
