hello world,
sorry if this is off topic, but the question arose when i was buidling
a test system with PHP4 / postgresql.
i want a user to enter a user ID and password in order to make a non-
permanent database connection. so the application (that consistes of
several PHP and HTML files) should remember the values in variables.
a logical approach seemed to be global variables, however, this doesn't
work when new pages are generated. in this small example:
// this is file main.php
<?php
echo "<html><body>";
$password="fubar";
echo "password is: \"$password\"<br>";
echo "<a href='sub.php'>sub</a>";
echo "</body></html>";
?>
// this is file sub.php
<?php
echo "<html><body>";
global $password; // doesn't work
echo "password is: \"$password\"<br>";
echo "</body></html>";
?>
the variable $password is not visible in sub.php. i guess this is
because the href link creates a new page, a fresh start. still i want
$password to be visible in sub.php. what is a good, safe way to do
this? setting serverside environment variables sounds dangerous. and i
would like to avoid cookies (unless it's the only way). i thought about
include_once(), but you can't call that from a link. or can you?
how is this normally done? TIA for any tips!
