This is weird. Did I only imagine that PHP allows numerical referencing of
associative array elements? 'Cuz suddenly the parser is calling all the
numerical references "undefined".
ex.
$my_arr['foo']='first';
$my_arr['bar']='second';
$my_arr['more']='third';
echo "<p>" . $my_arr[0] . "</p>\n";
echo "<p>" . $my_arr[1] . "</p>\n";
echo "<p>" . $my_arr[2] . "</p>\n";
for($i=0;$i<count($my_arr);$i++)
{
echo "<p>" . $my_arr[$i] . "</p>\n";
}
ex.
$my_arr=array(
'foo'=>'first',
'bar'=>'second',
'more'=>'third'
);
echo "<p>" . $my_arr[0] . "</p>\n";
echo "<p>" . $my_arr[1] . "</p>\n";
echo "<p>" . $my_arr[2] . "</p>\n";
for($i=0;$i<count($my_arr);$i++)
{
echo "<p>" . $my_arr[$i] . "</p>\n";
}
The above spits out nothing but a page full of "undefined offset" errors.
I can't find anything in the arrays chapter, nor in the array function
reference, to explain why the numerical referencing would've stopped
working. This *should* work, right? So why would it not be working now?
