Maybe I'm not understanding you correctly but have you looked into array_splice()
?
This answeranswer might also interest you.
function array_insert($input, $key, $value)
{
if (($key = array_search($key, array_keys($input))) !== false)
{
return array_splice($input, $key, 1, $value);
}
return $input;
}
This was the best I could come up with:
$a = array
(
'one' => 1,
'two' => 2,
'three' => 3,
'four' => 4,
'five' => 5,
'six' => 6,
);
ph()->Dump(next($a)); // 2
array_insert($a, 'four', array('new_item' => 100));
ph()->Dump(current($a)); // 2
function array_insert(&$array, $key, $data)
{
$k = key($array);
if (array_key_exists($key, $array) === true)
{
$key = array_search($key, array_keys($array)) + 1;
$array = array_slice($array, null, $key, true) + $data + array_slice($array, $key, null, true);
while ($k != key($array))
{
next($array);
}
}
}
ph()->Dump($a);
/*
Array
(
[one] => 1
[two] => 2
[three] => 3
[four] => 4
[new_item] => 100
[five] => 5
[six] => 6
)
*/
I don't think it's possible to set an array internal pointer without looping.
