mysql_からmysqli_へのPHPコードの移行

Question

PHP 5.3用に作成されたPHPコードがあります。PHP 5.6で使用する必要があるので、コードをmysql_からmyspli_に変換する必要があります。助けてください。 database.phpで

<?php 
$db_host = "localhost"; 
$db_username = "usr12345"; 
$db_password = "pass12345"; 
$database = "db12345"; 
?>

// If database.php does not exist then print error 
if (!include("database.php")) die("database.php could not be loaded!"); 
if ($db_host == "" || !isset($db_host)) die("please reinstall this panel"); 
//MySQL Verbindung wird getestet 
$connection = mysql_connect($db_host, $db_username, $db_password) or die ("database could not be connected"); 
$db = mysql_select_db($database) or die ("database could not be selected"); 
// Logincheck 
session_start(); 
// Language File check on DB 
$captcha_sql = mysql_query("SELECT language FROM settings WHERE id='0'"); 
$language_setting = mysql_result($captcha_sql,0); 
// Check if Language-file exists and include, else load English 
if (file_exists("./pages/messages/".$language_setting.".php")) { 
    $language_setting = $language_setting; 
} 
else { 
    $errors[] = "<h2>The language file could not be found, English is the default language!</h2>"; 
    $language_setting = "english"; 
} 
include "./pages/messages/".$language_setting.".php"; 
// Get variable for include 
if (!isset($_GET['include'])) { 
    $include_php = "main"; 
}

これは正常に動作する必要があります：

function mysqli_result($res,$row=0,$col=0){ 
    $numrows = mysqli_num_rows($res); 
    if ($numrows && $row <= ($numrows-1) && $row >=0){ 
     mysqli_data_seek($res,$row); 
     $resrow = (is_numeric($col)) ? mysqli_fetch_row($res) : mysqli_fetch_assoc($res); 
     if (isset($resrow[$col])){ 
      return $resrow[$col]; 
     } 
    } 
    return false; 
} 



// If database.php does not exist then print error 
    if (!include("database.php")) die("database.php could not be loaded!"); 
    if ($db_host == "" || !isset($db_host)) die("please reinstall this panel"); 
    //MySQL Verbindung wird getestet 
    $connection = mysqli_connect($db_host, $db_username, $db_password,$database) or die ("database could not be connected"); 
    //$db = mysql_select_db($database) or die ("database could not be selected"); 
    // Logincheck 
    session_start(); 
    // Language File check on DB 
    $captcha_sql = mysqli_query($connection,"SELECT language FROM settings WHERE id='0'"); 
    $language_setting = mysqli_result($captcha_sql,0); 
    // Check if Language-file exists and include, else load English 
    if (file_exists("./pages/messages/".$language_setting.".php")) { 
     $language_setting = $language_setting; 
    } 
    else { 
     $errors[] = "<h2>The language file could not be found, English is the default language!</h2>"; 
     $language_setting = "english"; 
    } 
    include "./pages/messages/".$language_setting.".php"; 
    // Get variable for include 
    if (!isset($_GET['include'])) { 
     $include_php = "main"; 
    } 
    else { 
     $include_php = $_GET['include'];  
    }
