I have a very handy utility for problems like this:
// Expand string array, & list all terms
function larec($array, $name) // List array recursive
{
if (is_array($array))
{
$j = count ($array);
$temp = array_keys($array);
$i = 0; while ($i < $j)
{
if(isset($array[$temp[$i]]))
{
$new_line = $name."['".$temp[$i]."']";
larec ($array[$temp[$i]], $new_line);
}
$i++;
}
}
else
{
echo '<p>'.$name.' = '.$array.'</p>';
}
}
If you have some array $foo then larec($foo,'Foo'); will list all the elements
of $foo
recursively, without any obvious limits. This makes it very easy to see what
you have
actually got, as opposed to what you thought you would get. The following is
an abridged
example of the result of listing an array $wkg_sys of mine, using:
larec ($wkg_sys,'Sys');
Sys['class'] = W
Sys['style']['0']['wkg_style'] = basic_tab
Sys['style']['0']['pad'] =
Sys['style']['0']['stripe'] = 0
Sys['style']['1']['wkg_style'] = nrml_style
Sys['style']['1']['pad'] = 1
Sys['style']['1']['stripe'] = 0
Sys['valid'] = 1
Sys['entries'] = 15
Sys['f_title'] = Developmental Web Page
Sys['version'] = IF1.4
Sys['ident'] = 0800
Sys['directory_id'] = 0000
Sys['index'] = 2
Sys['date'] = CCY2N
