Hello,
I have fatal error "Cannot redeclare openDatabase()". My script starts
with:
<?php
require_once 'include/common.inc.php';
require_once 'include/functions.inc.php';
require_once 'include/database.inc.php';
require_once 'include/announcement.inc.php';
require_once 'include/Captcha.php';
if ($_SERVER['REQUEST_METHOD'] != 'POST') {
error(ERRMSG_POST_ALLOWED_ONLY);
}
sessionBegin();
savePostInSession();
if (!openDatabase()) {
error(ERRMSG_DATABASE_ACCESS_PROBLEM);
}
where database.inc.php contains single definition of openDatabase():
<?php
require_once 'common.inc.php';
if (!isset($db)) {
$db = null;
}
$inTransaction = false;
$regions = array();
$estateTypes = array();
$ownership = array();
$standards = array();
$furnitureTypes = array();
$offerTypes = array();
$currencies = array();
$agencies = array();
$priceFor = array();
$units = array('M2' => 'm<sup>2<\/sup>', 'HA' => 'ha (hektarów)');
$vulgar = array();
function openDatabase() {
global $db;
try {
$db = new PDO('mysql:host=' . MYSQL_SERVER . ';dbname=' .
MYSQL_DATABASE, MYSQL_USER, MYSQL_PASSWORD);
$db->exec('SET NAMES latin2');
$db->exec('SET CHARACTER SET latin2 COLLATE latin2_general_ci');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
register_shutdown_function('closeDatabase');
} catch (PDOException $e) {
return false;
}
return true;
}
Remaining required_once files do not contain function openDatabase().

Either you've got another definition of openDatabase() somewhere and
don't realize it, or you are including (or requiring) database.inc.php
in one of your include files, probably without _once.

I never thought about this before, butnow that it came up, would it make
a difference if the database.inc.php was included in another included
file before this line
"require_once 'include/database.inc.php';"
or after (without a _once_). I would think that if it were included
first without a _once, then this current line would not be included
because it has a _once. If it occurs after this line, then it would be
doubly included because this line would be the first to include it.
If what I say is correct, then I would look in the code after this line.
What say you guys about my question?

We say that it's astonishing simple to test:
inc.txt
=======
Hello, World!
test.php
========
include 'inc.txt';
include_once 'inc.txt';
Run 'test.php' and count the number of hello worlds.

No, I don't.

The problem is somewhere in your code. The interpreter doesn't just put
out this message for no reason.
Most often this is caused by an include you forgot about. Other options
are files automatically included in the php.ini file, i.e. by the
auto_prepend_file directive, an include path which is not what you
expect, thereby including a different file than you expect, etc.

Building on Jerry's train of thought: Maybe you use some class that gets
autoloaded, and the include is done inside that class in some method?
