How to use the VLOOKUP function PHP removes specific array contents and rebuilds the array index

Copy the Code code as follows:

$a = Array (' A ', ' B ', ' C ', ' d ');
Unset ($a [2]);
Print_r ($a);

But the biggest drawback of this approach is that the array index is not rebuilt.
After checking the information. PHP provides this functionality. It's just that it's indirect.
This function is Array_splice.
For ease of use. I encapsulated it as a function. Easy for everyone to use.

Copy the Code code as follows:

Function Array_remove (& $arr, $offset) {
Array_splice ($arr, $offset, 1);
}
$a = Array (' A ', ' B ', ' C ', ' d ');
Array_remove ($a, 2);
Print_r ($a);

After testing you can know the location of the. 2 the element was actually deleted. and the index was re-established.
