README

This library tries to provide backward compatibility with the deprecated mysql_* functions.

Caveat

You really should not use this unless strictly needed: it's much better to refactor the existing code to use PDO and prepared statements directly or an ORM like Eloquent.

Although library provides an hackish replacement for mysql_real_escape_string, you ought to refactor your code to use prepared statements.

Requirements

PHP >= 5.6 with the PDO driver is required (PHP 7 is supported).

Installation

You can install mysql-compat via composer:

composer require mattbit/mysql-compat

Usage

The mysql_-equivalent functions are available through the facade class Mattbit\MysqlCompat\Mysql.

require __DIR__ . '/vendor/autoload.php';

use Mattbit\MysqlCompat\Mysql;

Mysql::connect('host', 'user', 'password');
Mysql::selectDb('my_db');

$result = Mysql::query('SELECT * FROM my_table');

$row = Mysql::fetchArray($result);

Note that the static methods are named in a camel-case like version of the original functions, e.g. mysql_fetch_array becomes Mysql::fetchArray.

If you are using PHP7 and want to re-define the old global functions and constants without touching existing code, you can use the Mysql::defineGlobals method:

require __DIR__ . '/vendor/autoload.php';

Mattbit\MysqlCompat\Mysql::defineGlobals();

mysql_connect('host', 'user', 'password');
mysql_select_db('my_db');

$result = mysql_query('SELECT * FROM my_table');

$row = mysql_fetch_array($result, MYSQL_BOTH);

If you need more control over the connections, the database manager allows you to access the underlying objects.

require __DIR__ . '/vendor/autoload.php';

use Mattbit\MysqlCompat\Mysql;

$manager = Mysql::getManager();

// Create a connection by specifying a custom DSN.
$connection = $manager->connect('mysql:dbname=mydatabase;host=myhost', 'user', 'pass');

// You can access the underlying PDO object
$pdo = $connection->getPdo();

// The rest of the code will use the last connection registered in the manager
$res = Mysql::query('SELECT * FROM my_table');

// But you can specify explicitly a connection as well
$res = Mysql::query('SELECT * FROM my_table', $connection);

This is particularly useful if you need to customize connection's DSN (e.g. to specify the charset):

$manager = Mysql::getManager();
$manager->connect('mysql:dbname=database;host=hostname;charset=customCharset', 'user', 'password');

// This will automatically use the connection above, with the right charset.
$res = Mysql::query('SELECT * FROM my_table');
