  $Query="SHOW COLUMNS FROM `$table` LIKE '$clname'";
  $result = $this->db->query($Query) or die("Get Enum value Query");
  if($result){
    $row = mysql_fetch_array( $result , MYSQL_NUM );
    $regex = "/'(.*?)'/";
    preg_match_all( $regex , $row[1], $enum_array );

PHP array merging & combine for associative array

Input array= array("test"=>array("s1"=>array(),"s2"=>array()))

foreach(array_keys($free_tim) as $k=>$v){
               //echo "$v===".count($free_tim[$v])."
";
               foreach((array_keys($free_tim[$v])) as $f=>$s){
                  foreach(($free_tim[$v][$s]) as $g=>$e){
                     $te[$v][] = $e;
                  }
               }
            }


Output array = array("test"=>array())
