You may have to count your way along the array with two pointers. A source address and a target address for a replacement array. The source address gets incremented each time through a loop to copy an element from one to the other, but within the loop there would be an extra increment to the target address and an insert of the zero in the position you want. Something like this may assist:-
I hope that this helps. It may well not be the most efficient way, but it depends how big an array you have and how many times you will run this.
All,
I would like to add the first 10 elements of an array. Here is how I am doing it now (only included first few add ops):

Hello to all,
I'm trying to separate the string "str" using a regex within match function.
The substrings that I want to separate, begin with 22, 23, 24 or 25 and followed by 12 or 14 characters. And I want to

The Seekable iterator.
INTERFACE SYNOPSIS
SeekableIterator
SeekableIteratorextends
Iterator
Methods
o abstractpublic void SeekableIterator::seek (int $position)
Inherited methods
o abstractpublic mixed Iterator::current (void )
o abstractpublic scalar Iterator::key (void )
o abstractpublic void Iterator::next (void )
o abstractpublic void Iterator::rewind (void )
o abstractpublic boolean Iterator::valid (void )
Example #1
Basic usage
This example demonstrates creating a custom SeekableIterator, seeking to a position and handling an invalid position.
<?php
class MySeekableIterator implements SeekableIterator {
private $position;
private $array = array(
"first element",
"second element",
"third element",
"fourth element"
);
/* Method required for SeekableIterator interface */
public function seek($position) {
if (!isset($this->array[$position])) {
throw new OutOfBoundsException("invalid seek position ($position)");
}
$this->position = $position;
}
/* Methods required for Iterator interface */
public function rewind() {
$this->position = 0;
}
public function current() {
return $this->array[$this->position];
}
public function key() {
return $this->position;
}
public function next() {
++$this->position;
}
public function valid() {
return isset($this->array[$this->position]);
}
}
try {
$it = new MySeekableIterator;
echo $it->current(), "
";
$it->seek(2);
echo $it->current(), "
";
$it->seek(1);
echo $it->current(), "
";
$it->seek(10);
} catch (OutOfBoundsException $e) {
echo $e->getMessage();
}
?>
The above example will output something similar to:
first element
third element
second element
