To pick every keys in a $_POST, set the post to a variable then use it as an Indexed arrays. For
example,
<?php
//Assuming the post value is has 3 fields name, age, address
$postvalue = array_keys($_POST);
echo $postvalue[0];
print "\n";
echo $postvalue[1];
print "\n";
echo $postvalue[2];
?>
The result will be
name
age
address
PS: Trying to access array_keys($_POST[0]) doesn't work in this case.
