PHP код:
<?
function db_connect()
{
global $db;
if ($db)
return;
$db = mysql_connect("localhost", MYSQLUSER, MYSQLPASS);
mysql_select_db(MYSQLDB, $db);
if (!$db)
{
echo "Couldn't open database!\n";
exit;
}
}
function db_disconnect()
{
global $db;
if ($db)
{
mysql_close($db);
$db = NULL;
}
}
function db_query($q)
{
global $db;
$result = mysql_query($q, $db);
return $result;
}
function db_fetch_array($result)
{
global $db;
$r = mysql_fetch_array($result);
return $r;
}
function db_query_row($q)
{
$result = db_query($q);
if (!$result)
return NULL;
$row = mysql_fetch_array($result);
return $row;
}
function db_query_value($q)
{
$row = db_query_row($q);
return $row[0];
}
function db_array_update($table, $a, $where)
{
$q = "update $table set ";
$b = NULL;
foreach($a as $key => $value)
{
if (is_int($key))
continue;
// if (isset($value) && $value != "")
$b[] = "$key='$value'";
}
$q .= implode(",", $b);
$q .= " where ".$where;
db_query($q);
}
function db_array_insert($table, $a)
{
$q = "insert into $table set ";
$b = NULL;
foreach($a as $key => $value)
{
if (is_int($key))
continue;
if ($value && $value != "")
$b[] = "$key='$value'";
}
$q .= implode(",", $b);
db_query($q);
}
function db_insert_id()
{
return mysql_insert_id();
}
function gen_id($table, $column, $size, $characters_allow)
{
for(;;)
{
$id = random_string($size, TRUE, $characters_allow);
$q = "select count(*) from $table where $column='$id'";

}
function db_num_rows($result)
