PHP MYSQL PDO - kompendium

Połączenie z bazą oraz ustawienie kodowania znaków na UTF-8

<source lang="php"> <?php /*** mysql hostname ***/ $hostname = 'localhost';

/*** mysql username ***/ $username = 'login';

/*** mysql password ***/ $password = 'haslo';

//baza danych $database='nazwabazydanych';

try {

   $dbh = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
   /*** echo a message saying we have connected ***/
   //echo 'Connected to database';
   }

catch(PDOException $e)

   {
   exit ($e->getMessage());
   }

$sql_set_utf = "SET CHARSET utf8"; $dbh->query($sql_set_utf);

mb_internal_encoding( 'UTF-8' ); ?> </source>

Bezpieczny INSERT czyli bindowanie

<source lang="php"> $b=$dbh->prepare("INSERT INTO users (`username`,`password`,`email`,`key`) VALUES (:username,:password,:email,:key)"); $b->bindValue(":username",$username); $b->bindValue(":password",$password); $b->bindValue(":email",$email); $b->bindValue(":key",$password); $b->execute(); </source>
