So, in this example code, we will try to remove that notice message.Īs we can see the above example code will delete the value of index 3 and the next value has been shifted to the 3rd and the same shifting for the other elements after index 3rd. Checking array is existing or not is always a good practice to check that array or that value printing. In this example, we will try to remove the above notice that is coming after the array reset. So, in this, we should not print array without checking if that array is existing or not. The warning is coming because we donât have that array reference after unset. Print_r($array1) // this line give notice as we have unset the $array1 before printing. Unset($array1) // unset the complete array. After this, we will unset that array and try printing to see how the code behaves. In this example, we will declare an array with some values and print those array elements using the print_r function.
