The Informix Platform for Doctrine DBAL gives support for Informix to Doctrine\DBAL the database abstraction layer of the Doctrine project.
DBAL | ifx4dd | |
---|---|---|
master | master | |
2.6 | 1.1 | |
2.5 | 1.0 |
Tested on Informix Dynamic Server versions 11.70 and 12.10 (right now it's not tested on 11.50 but should work anyway).
If you don't already have the PDO_INFORMIX extension for PHP you need install it (see PDO_INFORMIX), make sure that the extension works correctly before continue, you can do a quick connection test to your Informix server using the next example
<?php
$dsn = 'informix:'
. 'host=hosttest1;'
. 'server=test1tcp;'
. 'database=test_database;'
. 'protocol=onsoctcp;'
. 'service=50000;';
$user = 'your_user';
$password = 'your_password';
$con = new PDO($dsn, $user, $password);
if ($con) {
echo "The connection was successfully established\n";
}
You also will need composer in order to install all the dependencies, if you don't have it install it first.
Download the code of the Informix Platform for Doctrine DBAL or clone it with
git git clone https://github.com/josemalonsom/Ifx4dd.git
. Move to the
directory where you have the sources and install dependencies with composer
$ cd Ifx4dd/
$ composer install
it will install Doctrine\DBAL under the vendor directory and will create an autoloader class that you can find in the vendor/autoload.php file. The autoloader will add the Informix Platform directories in first place so that you can use the Informix Platform specific versions of some of the DBAL classes.
Simply execute:
composer require "josemalonsom/ifx4dd:dev-master"
it will install the libraries under the vendor
directory.
If you don't have experience with DBAL please read first its documentation Doctrine\DBAL documentation
To create a connection you can use the modified version of the DriverManager of Doctrine\DBAL with comes with the Informix Platform or you can use the original DriverManager class of Doctrine\DBAL, in this last case you will need to specify the driver class to use.
Ifx4dd comes with a modified version of the DriverManager class that adds
pdo_informix
as one of the possible drivers to use.
In this case, you need tell to composer
that load the classes from the ifx4dd
directory tree in first place (if you have installed ifx4dd from the composer.json
what comes with ifx4dd it is not needed since the ifx4dd directory is added
in first place to the autoloader).
<?php
// Gets the autoloader
$classLoader = require_once 'vendor/autoload.php';
// Adds the ifx4dd directory in first place to the
// Doctrine\DBAL namespace
$classLoader->add(
'Doctrine\\DBAL\\',
'vendor/josemalonsom/ifx4dd/lib',
true
);
use Doctrine\DBAL\DriverManager;
$connectionParams = array(
'driver' => 'pdo_informix',
'host' => 'hosttest1',
'port' => '50000',
'protocol' => 'onsoctcp',
'server' => 'test1tcp',
'dbname' => 'test_database',
'user' => 'user',
'password' => 'password',
);
$connection = DriverManager::getConnection($connectionParams);
If you want to use the 'Doctrine\DBAL\DriverManager' class what comes with DBAL you need to specify the driver class to use in the connection params as in the next example:
<?php
require_once 'vendor/autoload.php';
use Doctrine\DBAL\DriverManager;
$connectionParams = array(
'driverClass' => '\Doctrine\DBAL\Driver\PDOInformix\Driver',
'host' => 'hosttest1',
'port' => '50000',
'protocol' => 'onsoctcp',
'server' => 'test1tcp',
'dbname' => 'test_database',
'user' => 'user',
'password' => 'password',
);
$connection = DriverManager::getConnection($connectionParams);
Since DBAL 2.5 it is possible to use a URL to create the connection (note that in this case you must use the ifx4dd DriverManager version).
<?php
$classLoader = require_once 'vendor/autoload.php';
$classLoader->add(
'Doctrine\\DBAL\\',
'vendor/josemalonsom/ifx4dd/lib',
true
);
use Doctrine\DBAL\DriverManager;
$connection = DriverManager::getConnection(array(
'url' => 'informix://user:password@hosttest1:50000/test_database?protocol=onsoctcp&server=test1tcp'
));
Please, refer to the DBAL documentation for more information: https://github.com/doctrine/dbal/blob/2.5/docs/en/reference/configuration.rst
DBAL uses delimited identifiers so you need to enable it in your Informix environment, see enabling delimited identifiers.
