Actually it's not either...
Since you can't easily debug when generating XML, as malformed XML will STB,
I have this function which dumps out an array and recursively sub arrays.
It would be very useful to dump out the name of the variable as part of
this, as a lot of text is on the screen with all the tags and such.
It always annoyed me about print_r() that it doesn't tell you the variable
name either, so you have to always prefix it with an echo/print just above
the print_r.
/**
* Print out an array in XML form (useful for debugging)
* @access public
* @param string $myArray the array to output in XML format
* @version 1.0
* @date 07/19/05
* @todo It would be nice if we could extract the array's variable
name and output that as an attribute
*/
function print_r_xml($myArray)
{
print xmltag('ARRAY', null, 1);
foreach($myArray as $k => $v)
{
if (is_array($v))
print_r_xml($v);
else
print xmltag($k,htmlspecialchars($v));
}
print xmltag('ARRAY', null, 2);
}
