Conversione Codice da mysql a mysqli

[antoniobarone95]

Salve ragazzi devo convertire il codice da mysql a mysqli come posso procedere?

<?php

$username = "username";
$password = "password";
$hostname = "hostname";
$database = "database";

mysql_connect($hostname, $username, $password) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());
mysql_query("set names 'utf8'");

?>

<?php
$table_name = "cf_help_center"; //nome tabella del databse
$first_field = "title"; //campo tabella titolo
$second_field = "tag_faq"; //campo tag faq
$faq_software = "faq_software"; //campo tipo software faq
$cf_typology = "cf_typology"; //campo tipo software faq
$category_faq = "category_faq"; //campo categoria faq
$link_ancor = "link_ancor"; //campo link ancora faq
$limitchar = 3; //limitatore caratteri minimi
$records_number = 10;  // numero di ricerca per pagina
$page_number = 1;// pagina iniziale predefinita
?>

<?php

// file di connessione al database
include('inc/db.inc.php');

// file di configurazione
include('inc/config.inc.php');

// minim 3 characters condition
   if(strlen($_GET['terms']) < $limitchar) {
 echo '<div id="counter">'. $limitchar .' caratteri minimi</div>';
// no spaces in first 4 letters
  } else if(preg_replace('/[a-zA-Z0-9]/', ''))  {

Ciao Antonio!

Per prima cosa devi rimpiazzare tutti i campi mysql_* con i campi mysqli_*

Sicuramente nessuno scriverà il codice gratuitamente per te. Qui ti do un link con il quale puoi vedere i principali cambiamenti da fare al tuo codice.
