PHP array_pad Function

The array_pad() function inserts a value into an array up to the specified length.

Tip: If you assign a negative size parameter, the function will insert new elements BEFORE the original elements (See example below).

Note: This function will not delete any elements if the size parameter is less than the size of the original array.

The basic syntax of the array_pad() function is given with:

     array_pad(array, size, value);

The array_pad() function accepts the following parameters.

Example : 

If size is positive then the array is padded on the right, if it's negative then padded on the left.

Output :

Array
(
    [0] => online
    [1] => online
    [2] => Web
    [3] => Designing
    [4] => House
)
