Microsoft Drivers for PHP for SQL Server

Welcome to the Microsoft Drivers for PHP for SQL Server PHP 7

The Microsoft Drivers for PHP for SQL Server are PHP extensions that allow for the reading and writing of SQL Server data from within PHP scripts. The SQLSRV extension provides a procedural interface while the PDO_SQLSRV extension implements PDO for accessing data in all editions of SQL Server 2005 and later (including Azure SQL DB). These drivers rely on the Microsoft ODBC Driver for SQL Server to handle the low-level communication with SQL Server.

This release contains the SQLSRV and PDO_SQLSRV drivers for PHP 7 with improvements on both drivers and some limitations (see Limitations below for details). Upcoming release(s) will contain more functionality, bug fixes, and more (see Plans below for more details).

##Announcements

December 19, 2016: We are delighted announce that production release for PHP Linux Driver for SQL Server is available. PECL packages (4.0.8) are updated with the latest changes, and Linux binaries (4.0.8) compiled with PHP 7.0.14 are available for Ubuntu 15.04, Ubuntu 16.04, and RedHat 7.2. For complete list of changes please visit CHANGELOG file.

Please visit the blog for more announcements.

Build (Windows)

Note: if you prefer, you can use the pre-compiled binary found HERE

####Prerequisites

You must first be able to build PHP 7 without including these extensions. For help with doing this, see the official PHP website for building your own PHP on Windows.

####Compile the drivers

1. Copy the sqlsrv and/or pdo_sqlsrv source code directory from this repository into the ext subdirectory.

2. Run buildconf.bat to rebuild the configure.js script to include the driver.

3. Run configure.bat --with-odbcver=0x0380 and the desired driver options (as below) [plus other options such as --disable-zts for the Non Thread Safe build] to generate the makefile. You can run configure.bat --help to see what other options are available.

• For SQLSRV use: --enable-sqlsrv=shared
• For PDO_SQLSRV use: --enable-pdo=shared --with-pdo-sqlsrv=shared

4. Run nmake. It is suggested that you run the entire build. If you wish to do so, run nmake clean first.

5. To install the resulting build, run nmake install or just copy php_sqlsrv.dll and/or php_pdo_sqlsrv.dll to your PHP extension directory.

This software has been compiled and tested under PHP 7.0.8 using the Visual C++ 2015 compiler.

Install (Windows)

####Prerequisites

• A Web server such as Internet Information Services (IIS) is required. Your Web server must be configured to run PHP
• Microsoft ODBC Driver 11 or Microsoft ODBC Driver 13

####Enable the drivers

1. Make sure that the driver is in your PHP extension directory (you can simply copy it there if you did not use nmake install).

2. Enable it within your PHP installation's php.ini: extension=php_sqlsrv.dll and/or extension=php_pdo_sqlsrv.dll. If necessary, specify the extension directory using extension_dir, for example: extension_dir = "C:\PHP\ext"

3. Restart the Web server.

Install (Linux)

Following instructions shows how to install PHP 7.x, Microsoft ODBC driver, apache, and Microsoft PHP drivers on Ubuntu 15, 16 and RedHat 7. To see how to get PHP SQLSRV drivers running on Debian, please visit Wiki. Note that Debian is not officially supported and this instruction hasn't been tested in our test lab.

Ubuntu

sudo apt-get install libapache2-mod-php7.0 
sudo apt-get install apache2

RedHat

sudo yum install httpd

####PHP 7.1

Ubuntu

sudo apt-get install libapache2-mod-php7.1 
sudo apt-get install apache2

RedHat

sudo yum install httpd 

Step 4: Install the Microsoft PHP Drivers for SQL Server

sudo pecl install sqlsrv
sudo pecl install pdo_sqlsrv

*Note: it installs the stable version, for specific version you should set the version. For example, sudo pecl install sqlsrv-4.0.8

Step 5: Add the Microsoft PHP Drivers for SQL Server to php.ini

####PHP 7.0

Ubuntu

echo "extension=/usr/lib/php/20151012/sqlsrv.so" >> /etc/php/7.0/apache2/php.ini
echo "extension=/usr/lib/php/20151012/pdo_sqlsrv.so" >> /etc/php/7.0/apache2/php.ini
echo "extension=/usr/lib/php/20151012/sqlsrv.so" >> /etc/php/7.0/cli/php.ini
echo "extension=/usr/lib/php/20151012/pdo_sqlsrv.so" >> /etc/php/7.0/cli/php.ini

RedHat

echo "extension= /usr/lib64/php/modules/sqlsrv.so" > /etc/php.d/sqlsrv.ini
echo "extension= /usr/lib64/php/modules/pdo_sqlsrv.so" > /etc/php.d/pdo_sqlsrv.ini

####PHP 7.1

Ubuntu 16.04

echo "extension=/usr/lib/php/20160303/sqlsrv.so" >> /etc/php/7.1/apache2/php.ini
echo "extension=/usr/lib/php/20160303/pdo_sqlsrv.so" >> /etc/php/7.1/apache2/php.ini
echo "extension=/usr/lib/php/20160303/sqlsrv.so" >> /etc/php/7.1/cli/php.ini
echo "extension=/usr/lib/php/20160303/pdo_sqlsrv.so" >> /etc/php/7.1/cli/php.ini

RedHat

echo "extension= /usr/lib64/php/modules/sqlsrv.so" > /etc/php.d/sqlsrv.ini
echo "extension= /usr/lib64/php/modules/pdo_sqlsrv.so" > /etc/php.d/pdo_sqlsrv.ini

Step 6: Restart Apache to load the new php.ini file

Ubuntu

sudo service apache2 restart

RedHat

sudo apachectl restart 

*Note to RedHat users: SELinux is installed by default and runs in Enforcing mode. To allow Apache to connect to database through SELinux, do this sudo setsebool -P httpd_can_network_connect_db 1

Step 7: Create your sample app

Navigate to /var/www/html and create a new file called testsql.php. Copy and paste the following code in tetsql.php and change the servername, username, password and databasename.

<?php
$serverName = "yourServername";
$connectionOptions = array(
    "Database" => "yourDatabase",
    "Uid" => "yourUsername",
    "PWD" => "yourPassword"
);
//Establishes the connection
$conn = sqlsrv_connect($serverName, $connectionOptions);
//Select Query
$tsql= "SELECT @@Version as SQL_VERSION";
//Executes the query
$getResults= sqlsrv_query($conn, $tsql);
//Error handling
 
if ($getResults == FALSE)
    die(FormatErrors(sqlsrv_errors()));
?> 
 <h1> Results : </h1>
 <?php
while ($row = sqlsrv_fetch_array($getResults, SQLSRV_FETCH_ASSOC)) {
    echo ($row['SQL_VERSION']);
    echo ("<br/>");
}
sqlsrv_free_stmt($getResults);
function FormatErrors( $errors )  
{  
    /* Display errors. */  
    echo "Error information: <br/>";  
  
    foreach ( $errors as $error )  
    {  
        echo "SQLSTATE: ".$error['SQLSTATE']."<br/>";  
        echo "Code: ".$error['code']."<br/>";  
        echo "Message: ".$error['message']."<br/>";  
    }  
}  
?>

Step 8: Run your sample app

Go to your browser and type in http://localhost/testsql.php You should be able to connect to your SQL Server/Azure SQL Database.

The drivers are distributed as shared binary extensions for PHP. They are available in thread safe (_ts.so) and-non thread safe (_nts.so) versions. The source code for the drivers is also available, and you can choose whether to compile them as thread safe or non-thread safe versions. The thread safety configuration of your web server will determine which version you need.

Sample Code

For samples, please see the sample folder. For setup instructions, see [here] phpazure

Limitations

• This release contains the PHP 7 port of the SQLSRV and PDO_SQLSRV drivers, and does not provide backwards compatibility with PHP 5.
• Binding output parameter using emulate prepare is not supported.
• Linux
  • ODBC 3.52 is supported but not 3.8.
  • Connection using named instances using '' is not supported.
  • Local encodings other than UTF-8 are not supported, and SQLSRV_ENC_CHAR only supports ASCII characters with ASCII code of 0 to 127.

Known Issues

• User defined data types and SQL_VARIANT.
• Binary column binding with emulate prepare (issue#140 )
• Linux
  • The following features are not supported with connection pooling:
    • PDO is only supported with unixODBC 2.3.1.
    • Unicode connection strings
    • sqlsrv_server_info and sqlsrv_client_info return false
    • In certain scenarios a generic error message maybe returned instead of a specific error when pooling is disabled
    • When retrieving data from columns with a data type of XML, varchar(max), nvarchar(max), or varbinary(max) no data maybe returned or the data maybe truncated depending on the length of the data in the source table.

Future Plans

• Expand SQL 16 Feature Support (example: Always Encrypted).
• Build Verification/Fundamental Tests.
• Bug Fixes.

Guidelines for Reporting Issues

We appreciate you taking the time to test the driver, provide feedback and report any issues. It would be extremely helpful if you:

• Report each issue as a new issue (but check first if it's already been reported)
• Try to be detailed in your report. Useful information for good bug reports include:
  • What you are seeing and what the expected behaviour is
  • Can you connect to SQL Server via sqlcmd?
  • Which driver: SQLSRV or PDO_SQLSRV?
  • Environment details: e.g. PHP version, thread safe (TS) or non-thread safe (NTS), 32-bit &/or 64-bit?
  • Table schema (for some issues the data types make a big difference!)
  • Any other relevant information you want to share
• Try to include a PHP script demonstrating the isolated problem.

Thank you!

FAQs
