please note that if you need to re-index a numeric array after and unset by offset and preserve
order array_merge with only one argument will output an array keyed sequentially
<?php
$arr = array(1,2,3,4,5);
unset($arr[2]);
var_dump($arr);
$arr = array_merge($arr);
var_dump($arr);
?>
--output--
array(4) {
[0]=>
int(1)
[1]=>
int(2)
[3]=>
int(4)
[4]=>
int(5)
}
array(4) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(4)
[3]=>
int(5)
}
