Here is the original code: http://pastebin.com/DNxtmApY. I'm not that interested in prepared statements at the moment, I just want this wrapper updating to MySQLi so once MySQL becomes depreciated I haven't got to update a billion websites.
Here is my attempt at converting to MySQLi.
<?
$database_host = "127.0.0.1";
$database_user = "user";
$database_pass = "pass";
$database_name = "name";
$db = new database($database_host, $database_user, $database_pass, $database_name);
class database {
var $link, $result;
function database($host, $user, $pass, $db) {
$this->link = mysqli_connect($host, $user, $pass, $db) or $this->error();
mysqli_select_db($db, $this->link) or $this->error();
}
function query($query) {
$this->result = mysqli_query($query, $this->link) or $this->error();
$this->_query_count++;
return $this->result;
}
function countRows($result = "") {
if ( empty( $result ) )
$result = $this->result;
return mysqli_num_rows($result);
}
function fetch($result = "") {
if ( empty( $result ) )
$result = $this->result;
return mysqli_fetch_array($result);
}
function fetch_num($result = "") {
if ( empty( $result ) )
$result = $this->result;
return mysqli_fetch_array($result, mysqli_NUM);
}
function fetch_assoc($result = "") {
if ( empty( $result ) )
$result = $this->result;
return mysqli_fetch_array($result, mysqli_ASSOC);
}
function escape($str) {
return mysqli_real_escape_string($str);
}
function error() {
if ( $_GET["debug"] == 1 ){
die(mysqi_error());
} else {
echo "Error in db code";
}
}
}
function sanitize($data) {
//apply stripslashes if magic_quotes_gpc is enabled
if(get_magic_quotes_gpc())
$data = stripslashes($data);
// a mysqli connection is required before using this function
$data = trim(mysqli_real_escape_string($data));
return $data;
}
However it chucks all sorts of errors:
Warning: mysql_query(): Access denied for user 'www-data'@'localhost'
(using password: NO) in /home/count/Workspace/lib/classes/user.php on
line 7 Warning: mysql_query(): A link to the server could not be
