PDO_MYSQL-DSN(3) 1 PDO_MYSQL-DSN(3)PDO_MYSQL DSN - Connecting to MySQL databases
The PDO_MYSQL Data Source Name (DSN) is composed of the following elements:
o DSN prefix
- The DSN prefix is mysql:.
o host - The hostname on which the database server resides.
o port - The port number where the database server is listening.
o dbname - The name of the database.
o unix_socket - The MySQL Unix socket (shouldn't be used with host or port).
o charset - The character set. See the character set concepts documentation for more information. Prior to PHP 5.3.6, this element
was silently ignored. The same behaviour can be partly replicated with the PDO::MYSQL_ATTR_INIT_COMMAND driver option, as the fol-
lowing example shows.
Warning
The method in the below example can only be used with character sets that share the same lower 7 bit representation as
ASCII, such as ISO-8859-1 and UTF-8. Users using character sets that have different representations (such as UTF-16 or Big5)
must use the charset option provided in PHP 5.3.6 and later versions.
Example #1
Setting the connection character set to UTF-8 prior to PHP 5.3.6
<?php
$dsn = 'mysql:host=localhost;dbname=testdb';
$username = 'username';
$password = 'password';
$options = array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
);
$dbh = new PDO($dsn, $username, $password, $options);
?>

PDO_MYSQL DSN examples
The following example shows a PDO_MYSQL DSN for connecting to MySQL databases:
mysql:host=localhost;dbname=testdb
mysql:host=localhost;port=3307;dbname=testdb
mysql:unix_socket=/tmp/mysql.sock;dbname=testdb
Note
Unix only:
When the host name is set to "localhost", then the connection to the server is made thru a domain socket. If PDO_MYSQL is compiled
against libmysqlclient then the location of the socket file is at libmysqlclient's compiled in location. If PDO_MYSQL is compiled
against mysqlnd a default socket can be set thru the pdo_mysql.default_socket setting.
