[PHPLIB] Array/object traversal shows php3, phplib data From: Gary Bickford (garyb <email protected>)
Date: 02/22/00

The following code is a useful little toy. Include it at the end of the
auto_append footer. Then, if $dbg is >0, all the information you want
to know is available. I have included three example usages - the PHP
variables, the PHPLib variables, and a test array. There's never
anything in $GLOBALS or $ENV - I don't know what the correct usage is in
those cases. I'm open to suggestion/improvement.

==================================================
<? if (!isset ($dbg)) { // Turn on/off for debugging ?>
</body>
</html>
<?
        exit;
} else {
        function pray ($data, $functions=0) {
                // pray - short for print_array
                // Traverse the argument array/object recursively
and print an ordered list.
                // Optionally show function names

                if($functions!=0) { $sf=1; } else { $sf=0 ;} // This

                if (isset ($data)) {
                        if (is_array($data) || is_object($data)) {
                                if (count ($data)) {
                                        echo "<OL>\n";

                                        echo "(empty)";
        } } } }

// $mylist contains various other arrays, so we can find out everything
in one traverse.

names, add ",1" in the arguments
