How to delete elements (unset, array_splice) in the PHP array )?

If you want to delete an element from an array, you can use unset directly, but the index of the array will not be rearranged:

<? Php $ arr = array ('A', 'B', 'C', 'D'); unset ($ arr [1]); print_r ($ arr );

The result is:

Array ([0] => a [2] => c [3] => d)

So how can we fill in the missing elements and re-index the array? The answer is array_splice ():

<? Php $ arr = array ('A', 'B', 'C', 'D'); array_splice ($ arr, 1, 1); print_r ($ arr );

The result is:

Array ([0] => a [1] => c [2] => d)
