Installation and Usage Example

Installation and Usage Example -- Installation and example for the usage of MDB2_Schema


First you need MDB2 installed:

$ pear install --alldeps MDB2

You should install a driver for each database you are working with. For MySQL it would be:

$ pear install MDB2_Driver_Mysql

For some hints refers to MDB2 documentation or try in a UNIX-like system:

$ pear remote-list | grep MDB2

MDB2_Schema is a separate package, and can also be installed using the PEAR installer:

$ pear install --alldeps MDB2_Schema-beta

now you should be ready :)

Usage Example

To create an instance of the MDB2_Schema class you can use the factory(), which accepts a $dsn or an array. The factory method also accepts an existing MDB2 object. In the example below, we will just use a $dsn.

require_once 'MDB2/Schema.php';

$options = array(
    'log_line_break' => '<br>',
    'idxname_format' => '%s',
    'debug' => true,
    'quote_identifier' => true,
    'force_defaults' => false,
    'portability' => false
$dsn = 'mysql://root:@localhost/MDB2Example';

$schema =& MDB2_Schema::factory($dsn, $options);

if (PEAR::isError($schema)) {
    $error = $schema->getMessage();

if (isset($error)) {
