dimension array to separate key

   /**

     * This function will convert dimension array to array with key is

     * conbine all keys of original array

     *

     * Example:

          // ORIGINAL ARRAY

          // array (size=6)

          // 0 => string 'word' (length=4)

          // 1 => string 'my name' (length=7)

          // 2 =>

          //   array (size=2)

          //     0 => string 'calander name 1' (length=15)

          //     1 => string 'calander name 2' (length=15)

          // 3 => string 'Monday' (length=6)

          // 4 =>

          //   array (size=2)

          //     0 =>

          //       array (size=2)

          //         0 => string 'week 1.1' (length=8)

          //         1 =>

          //           array (size=2)

          //             0 => string 'week 1.2.1' (length=10)

          //             1 => string 'week 1.2.2' (length=10)

          //     1 => string 'week 2' (length=6)

          // 5 => string 'key word' (length=8)

          ---->>

          // array (size=10)

          // 'hello' => string 'word' (length=4)

          // 'myName' => string 'my name' (length=7)

          // 'calander.subCal1' => string 'calander name 1' (length=15)

          // 'calander.subCal2' => string 'calander name 2' (length=15)

          // 'today' => string 'Monday' (length=6)
