I have a problem on my site, it all started after I received a MySQL discontinuation message, and they asked me to change it to MySQLi, after I changed a series of codes appeared on my page, what should I do to to fix the errors?
The initial error was, as follows:
Deprecated: mysql_connect (): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead /home/vagalume/public_html/decor/system/database/mysql.php on line 6 Warning: session_start (): Can not send session cookie - headers already sent by (output started at /home/vagalume/public_html/decor/system/database/mysql.php:6) in /home/vagalume/public_html/decor/system/library/session.php on line 11Warning: session_start (): Can not send session cache limiter - headers already sent (output started at /home/vagalume/public_html/decor/system/database/mysql.php:6) in /home/vagalume/public_html/decor/system/library/session.php on line 11Warning: Can not modify header information - headers already sent by (output started at /home/vagalume/public_html/decor/system/database/mysql.php:6) in /home/vagalume/public_html/decor/system/library/currency.php on line 45
The code I currently have:
<?php
final class MySQL {
private $link;
public function __construct($hostname, $username, $password, $database) {
if (!$this->link = mysql_connect($hostname, $username, $password)) {
trigger_error('Error: Could not make a database link using ' . $username . '@' . $hostname);
}
if (!mysql_select_db($database, $this->link)) {
trigger_error('Error: Could not connect to database ' . $database);
}
mysql_query("SET NAMES 'utf8'", $this->link);
mysql_query("SET CHARACTER SET utf8", $this->link);
mysql_query("SET CHARACTER_SET_CONNECTION=utf8", $this->link);
mysql_query("SET SQL_MODE = ''", $this->link);
}
public function query($sql) {
if ($this->link) {
$resource = mysql_query($sql, $this->link);
if ($resource) {
if (is_resource($resource)) {
$i = 0;
$data = array();
while ($result = mysql_fetch_assoc($resource)) {
$data[$i] = $result;
$i++;
}
mysql_free_result($resource);
$query = new stdClass();
$query->row = isset($data[0]) ? $data[0] : array();
$query->rows = $data;
$query->num_rows = $i;
unset($data);
return $query;
} else {
return true;
}
} else {
trigger_error('Error: ' . mysql_error($this->link) . '<br />Error No: ' . mysql_errno($this->link) . '<br />' . $sql);
exit();
}
}
}
public function escape($value) {

}
}
