What is "php_track_vars" function?

[fabiuz]

What does it do ?

php_track_vars

[Anon]

This tells PHP whether to make available all of the variables passed to the page through POST/GET/COOKIES in to the array's HTTP_POST_VARS, HTTP_GET_VARS, HTTP_COOKIE_VARS respectively.

Hope that helps.

How would I extract the names from $HTTP_POST_VARS? I turn on php_track_vars, and I do the following:

$form_vars = count($HTTP_POST_VARS);

for ($i=0; $i < $form_vars; $i++) {
$a = $HTTP_POST_VARS[$i];
echo $a,"<BR>";
}

$a should have the value of $HTTP_POST_VARS[$i], but it's empty. I'm trying to extract the name and value of the form variable in $HTTP_POST_VARS.

Thanks,

Ack! I finally stumbled across the solution:

for ($i; $i < sizeof ($HTTP_POST_VARS); $i++) {
//Display the key
echo key($HTTP_POST_VARS)."<BR>";
//Display the value of the key
echo key($HTTP_POST_VARS)."<BR>";
next ($HTTP_POST_VARS);
}
