<?php
$v = array();

$v['0'] = 's';
$v[0] = 'i';
echo $v['0'];
echo $v[0];

$v['.1'] = 's';
$v[.1] = 'i';
echo $v['.1'];
echo $v[.1];

$v['0.1'] = 's';
$v[0.1] = 'i';
echo $v['0.1'];
echo $v[0.1];

// output: iisi

foreach($v as $key => $val) echo $v[$key] . ' : ' . $val . "\r\n";

// output: iisi
?>

This means foreach preserves the key data type, it also means arrays distinguish between float numbers and float like  strings, unlike integers
