I have string. for example
$string = 1234567;
or
$string = 1976324
How i can split each second. for example.
[0=>1357, 1=>246];
or
[0=>1734, 1=>962];

You could also use a combination of str_split, array_chunk and array_column.
I am not recommending this, rather presenting another, alternate way of processing this that gave me some fun ;)
Note :
array_column()requires PHP 5.5+.
Example Code :
php > $string = 1234567;
php > print_r(array_column(array_chunk(str_split($string, 1), 2), 0));
Array
(
[0] => 1
[1] => 3
[2] => 5
[3] => 7
)
php > print_r(array_column(array_chunk(str_split($string, 1), 2), 1));
Array
(
[0] => 2
[1] => 4
[2] => 6
)
Of course you may also concatenate that into strings:
php > echo implode('', array_column(array_chunk(str_split($string, 1), 2), 1));
246
php > echo implode('', array_column(array_chunk(str_split($string, 1), 2), 0));

your answer not so good because eating extra resources. you calling twice 4 functions. for each iteration
You can do this way:
<?php
$string = 1234567;
$string = (string)$string;
$tmp[0] = "";
$tmp[1] = "";
for($i = 0; $i < strlen($string);$i++)
{
if($i % 2)
{
$tmp[1] .= $string[$i];
}
else
{
$tmp[0] .= $string[$i];
}
}
print_r($tmp);
?>
