foreach loops with arrays

[Anon]

consider this PHP code:

<?
$test = array ('zero','one','hello'=>'two','three','four');
foreach ($test as $key => $value) {
if ($key == 'hello')
{$value = "<a href=\"link\">$value</a>";}
echo "$key : $value<br>\n";
}
?>

When this code is parsed, the "zero" and "two" array idexes both become hypertext links. Why? Shouldn't only the "two" index be a link by virtue of the conditional statement?

Hi Devin,
The result you got is 'cas of the data type.You are not setting any values to 'zero','one','three','four' so,they will be treated as values and keys will be 0,1,2,3
and if you convert the string to INT the value is ZERO.
Convert the Key value to String before comparing you will get the result
i.e $key = (string) $key;
