"david@petshelter.net" mentioned that using foreach() on an associative array goes through
each element twice. Here's a hack to get around that. Instead of...
foreach($myarray as $key => $value)
echo "Key: $key; Value: $value<br />\n";
...use...
foreach($myarray as $key => $value)
if(strval(intval($key))!=$key)
echo "Key: $key; Value: $value<br />\n";
This then only acts on the associative keys. If you want to use only the numerical keys, change the
comparator in the IF from "!=" to "==".
Hope this helps!
