Return 5 elements, inserting the value “blue” into the new positions in the array:
| <?php $a=array(“red”,“green”); print_r(array_pad($a,5,“blue”)); ?> |
The array_pad() function adds a specified number of elements with a given value to an array.
Tip: If a negative size parameter is used, the function will insert new elements before the original elements (see example below).
Note: This function does not remove any elements if the size parameter is less than the size of the original array.
