How to get all test cases from a project through testlink api?

Question

I can only see methods to retrieve the test cases if they are bind with any plan. (getTestCasesForTestPlan). I want to retrieve all the test cases written by the user before its used in a plan. Basically, I want to track the count of test cases, written by, created at, all such data before hand (before adding to test plan) through testlink API.

Any suggestions would be appreciated.

Giving answer to my own question. I have written a code to implement my question with the help of @fman.

/**
   * Gets a list of test case id's within a project
   *
   * @param struct $args
   * @param string $args["devKey"]
   * @param int $args["testprojectid"]
   * @return mixed $resultInfo
   *         
   * @access public
   */   
  public function getProjectTestCases($args){     
   $messagePrefix="(" .__FUNCTION__ . ") - ";

    $this->_setArgs($args);
    $checkFunctions = array('authenticate','checkTestProjectID');       
    $status_ok=$this->_runChecks($checkFunctions,$messagePrefix);       

    if($status_ok)
    {
      $testProjectID = $this->args[self::$testProjectIDParamName];
      $info=$this->tprojectMgr->get_all_testcases_id($testProjectID, $tcid = []);
      if( !is_null($info) && count($info) > 0 )
      {
          $info = array_values($info);
      }
      return $info;  
    }
    else
    {
      return $this->errors;
    } 
  }

I got some advice from testlink at their forum.
