<?php
$a = array('0' => 'zero'); // '0'
// is different from
$b = '0'; // '0'
?>
Because when you use array, it will automatically change the key to integer if it could.
So, it output:
>php -r "print var_dump(array_keys(array('0' => '
zero', '1' => 'one')));"
array(2) {
[0]=>
int(0)
[1]=>
int(1)
}
They are int type, not string.
