i really should get a full night's sleep before posting. so you just want to
store the name and email information. well, there are not hundreds of
examples on the net...there are thousands. start with mysql. here's a sample
table:
CREATE TABLE people
(
Id INT AUTO_INCREMENT PRIMARY KEY
,
FirstName VARCHAR(30) NOT NULL
,
MiddleName VARCHAR(30) NULL
,
LastName VARCHAR(50) NOT NULL
,
UserName VARCHAR(51) NULL
,
Password VARCHAR(50) NOT NULL
,
Phone VARCHAR(50) NULL
,
Email VARCHAR(255) NOT NULL
,
Expired NUMERIC NULL DEFAULT 1
,
Passport VARCHAR(40) NULL DEFAULT ''
,
Stamp TIMESTAMP NULL DEFAULT NOW()
ON UPDATE NOW()
);
notice, the table integrates some security tie-ins?
========== here's an abstract db class. this one uses mysql. you'll see it
used in subsequent code posted below.
<?
class db
{
static private $_instance = null;
static private $_lastStatement = '';
private function __clone(){}
private function __construct(){}
static function connect($server, $user, $password, $catalog = null)

mysql_connect($server, $user, $password);
if (!is_null($catalog)){ mysql_select_db($catalog); }
} catch (exception $ex) {
print "<pre>\r\n" . $ex->getMessage() . "\r\n" .
' in file ' . $ex->getFile() . "\r\n" .
' on line ' . $ex->getLine() . "\r\n" .
'</pre>';
return false;
}
return true;
}
static function getInstance()
{
if (is_null(self::$_instance)){ self::$_instance = new db(); }
return self::$_instance;
}
static function getLastStatement(){ return self::$_lastStatement; }

{

{

}
}
return $columns;
}
static function encode($string)
{

$string = strtr($string, $translation);
return $string;
}

{

while ($row = @mysql_fetch_array($records, MYSQL_NUM))
{
for ($i = 0; $i < $fieldCount; $i++)
{
$value = $row[$i];
if ($decode){ $value = strtr($value, $translation); }
$array[$key][strtoupper(@mysql_field_name($records, $i))] = $value;
}
$key++;
}
if ($returnNewId)
{
$array = array();
$array[0]['ID'] = mysql_insert_id();
}
@mysql_free_result($records);
return $array;
}
static function prepare($string, $encode = false)
{
if ($encode){ $string = self::encode($string); }
$string = stripslashes(str_replace("'", "''", $string));
return $string;

text-wrapping)
