I’m kind of a newbie PHP programmer and never heard about PDO until a few days ago. Up until now I have just used the default MySQL functions in PHP for my website, but from what I’ve been reading it seems like I really should switch to PDO.

I recompiled Apache, enabling PDO, but when I try to connect with the following code:

try 
{
    $dbh = new PDO('mysql:host=localhost;dbname=' . $dbname, $user, $pass);
}
catch (PDOException $e) 
{
    print "Error!: " . $e->getMessage() . "<br/>";
    die();
}

I get the error:

Error!: could not find driver

I ran phpinfo() and found the following relevant to PDO:

‘./configure’ ‘–disable-fileinfo’ ‘–disable-phar’ ‘–enable-bcmath’
‘–enable-calendar’ ‘–enable-ftp’ ‘–enable-gd-native-ttf’
‘–enable-libxml’ ‘–enable-magic-quotes’ ‘–enable-mbstring’
‘–enable-pdo=shared’ ‘–enable-sockets’ ‘–prefix=/usr/local’
‘–with-apxs2=/usr/local/apache/bin/apxs’ ‘–with-curl=/opt/curlssl/’
‘–with-freetype-dir=/usr’ ‘–with-gd’ ‘–with-gettext’
‘–with-imap=/opt/php_with_imap_client/’ ‘–with-imap-ssl=/usr’
‘–with-jpeg-dir=/usr’ ‘–with-kerberos’
‘–with-libxml-dir=/opt/xml2/’ ‘–with-mcrypt=/opt/libmcrypt/’
‘–with-mysql=/usr’ ‘–with-mysql-sock=/var/lib/mysql/mysql.sock’
‘–with-mysqli=/usr/bin/mysql_config’ ‘–with-openssl=/usr’
‘–with-openssl-dir=/usr’ ‘–with-pcre-regex=/opt/pcre’
‘–with-pdo-sqlite=shared’ ‘–with-png-dir=/usr’
‘–with-sqlite=shared’ ‘–with-xpm-dir=/usr’ ‘–with-zlib’
‘–with-zlib-dir=/usr’

PDO
PDO support enabled
PDO drivers     sqlite, sqlite2

pdo_sqlite
PDO Driver for SQLite 3.x   enabled
SQLite Library  3.7.7.1

How do I get PDO working?

Thanks for your help!

    You should also add the pdo-mysql extension:

    --with-pdo-mysql=shared

    Some extra info:

    Also always add the encoding of the database:

    $dbh= new PDO('mysql:dbname=dbtest;host=127.0.0.1;charset=utf8', 'user', 'pass');

    Always disable emulated prepared statements (for mysql)

    $dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    Since you are just starting with PDO I also suggest this tutorial: http://wiki.hashphp.org/PDO_Tutorial_for_MySQL_Developers
