We can use var_dump() or print_r() to display the values of an array in human-readable format or to see the output value of the program array. To display array structure and values in PHP, we can use two functions. This can be done directly, in this deletion process, first, we have to find out the position of that element then we can delete that element by using the unset() function by passing the position as a parameter.An array in PHP is a type of data structure that can store multiple elements of similar data type under a single variable. 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.
