Introduction

While Microsoft® SQL Server® 2008 is the recommended database to use when hosting PHP applications on an Internet Information Services 7 (IIS 7) and above Web server, you can also use MySQL as the database. Currently, many popular PHP applications use MySQL Server for data storage. Using MySQL requires hosting providers to include MySQL database support with the hosting packages.

The mysqli extension was introduced with PHP version 5.0.0. The MySQL Native Driver was included in PHP version 5.3.0. >On Windows, PHP is most.

MySQL cannot currently be installed with the Microsoft® Web Platform Installer (Web PI). This article provides guidance for installing MySQL manually.

Install MySQL Server on Windows Server 2008 or Windows Server 2008 R2

It is recommended that you install MySQL on a dedicated server rather than installing MySQL on the same server that is running IIS. The separation of database server and Web server makes overall installation more secure and manageable and avoids resource contentions between the database and Web server processes.

  1. Download MySQL Community Server. We recommend downloading Windows® Installer.
  2. Start Windows Installer, or extract all the files from the archive, and then start Setup.exe.
  3. You can use a Typical Setup or customize the installation to suit your needs.
  4. Once the installation wizard is completed, it is recommended that you leave the Configure the MySQL Server now check box selected.

Configure a MySQL Instance

  1. Run the MySQL Server Instance Configuration Wizard, and then choose the configurations options that most closely match your environment.
    For more information, see the Server Instance Configuration Wizard.
    Best practice recommendations are as follows:

    • Click Next in the Instance Configuration Wizard.
    • Select Detailed Configuration, and then click Next.
    • Select a server type that best suits your environment. It is recommended to set up a separate MySQL server; when prompted to select a server type, select Dedicated MySQL Server Machine, and then click Next.
    • Select a database option, and then click Next.

      • Select either the Multifunctional Database or Transactional Database Only options if you are using the InnoDB storage engine or the high-speed MyISAM storage engine (for example, if the Web applications on your server require multi-statement transactions, advanced isolation levels and row-level locking, foreign key constraints, or atomic, consistent, isolated, and durable [ACID] features). These options provides fully ACID transactional capabilities, but at the cost of more aggressive usage of disk space and memory.
      • Otherwise, use the Non-Transactional Database Only option, which is optimized for high-performance SELECT operations. It has low overhead, in terms of memory usage and disk utilization, but at the cost of not supporting transactions.
    • Choose the option that sets the number of concurrent connections you need.

      Note

      Connections require memory; if the number you choose is too big, your server may not have enough memory.

    • You may adjust networking settings to suit your environment or accept defaults, and then click Next.
    • Select the default character set that best suits you, and then click Next.
    • We recommend enabling both Windows options here. Select both check boxes, and then click Next.
    • Type the password you want to use for the root account, and then click Next.
    • Click Execute to apply your settings.
    • Click Finish to close the wizard.
  • For PHP to work with MySQL, it is necessary to perform the following modifications to the Php.ini file:

    • Confirm that the extension_dir points to the folder where all PHP loadable extensions are located, frequently in the Ext folder (for example, extension_dir='.ext').
    • Enable dynamic extension for MySQL by uncommenting the corresponding line for the MySQL extension: extension=php_mysql.dll
    • c. Save and close the Php.ini file.

Secure MySQL

  1. Remove the anonymous database account (if it exists). Open the MySQL command prompt by clicking Start -> All Programs -> MySQL -> MySQL Server 5.1 -> MySQL Command Line Client:
  2. Enter the password for the root account.
  3. Once logged on to MySQL, use the following sequence of commands:

  4. Next, restrict the root account to log on only from localhost. Open a MySQL command prompt, and use the following sequence of commands:

  5. Change the name of the root user with the following sequence of commands from the command prompt:

Provision the User and Database

Install mysqli extension
  1. To provision a new user, type the following command from the MySQL command prompt:

  2. The newly created user does not have any privileges on the MySQL server by default. To create a new database, type the following command:

  3. To grant access to this database for a particular user, type the following command:

Configure PHP to Access MySQL

  1. Open the c:phpphp.ini file with your favorite text editor.
  2. Uncomment the following lines by removing the semicolon:

  3. Restart the IIS service by clicking on Start, selecting the Search Field, typing iisreset, and then pressing ENTER.
  4. If all went well, you should see the mysqli section on the PHP information page created earlier http://localhost/phpinfo.php.

    Figure 1: The mysqli section on the PHP information page

Best Practices for MySQL

  • Enable TCP/IP Networking — This is the default. Keep the TCP port that MySQL uses to listen at 3306. If the database will be running on a separate system from the Web server, select the Add firewall exception for this port check box.
  • Include Bin Directory in Windows PATH — This makes the MySQL utilities available from the command prompt or from Windows PowerShell™.
  • Create an Anonymous Account — The default is to keep this disabled. Adding anonymous user support may create a security risk for the database; additionally, enabling anonymous users causes the GRANT statements used to set up database to be unreliable.

I upgraded to PHP 5.3, and noticed that php_mssql.dll is missing. After googling a bit, it seems that 5.3 has dropped support for mssql. So I downloaded the drivers from microsoft, but I can't seem to get it to work.

I am on windows. What do I need to do, after I unzip the files in the ext directory of my PHP 5.3?

Quoting http://php.net/manual/en/intro.mssql.php:

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

Once you downloaded that, follow the instructions at this page:

In a nutshell:

Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:

Restart the Web server.

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.

The drivers can also be used with PDO.

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

Mysql Php Extension Missing

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.
