2. Agenda PHP on Windows How to make PHP fly on IIS SQL Server Driver for PHP Web Platform Installer Community PHP on Windows Azure What is the Microsoft Cloud? Deploying a PHP application to the cloud Windows Azure SDKs and Tools for PHP Questions / Open Discussion

3. FastCGI Fast and Reliable. v1.0 released in Oct 2007 v1.5 released in Nov 2009 Consistent set of features across all IIS versions: FastCGI in IIS 7.5 – new features included in OS FastCGI in IIS 7.0 – install the FastCGI update (http://www.iis.net/expand/FastCGI) FastCGI in IIS 5.1/IIS 6.0 – install FastCGI 1.5 extension Recommended way of running PHP on Windows

4. FastCGI (cont.) New features: Auto-tuning of maxInstances Automatic recycling of PHP processes when php.ini changes Useful tips Use latest version of FastCGI and turn on dynamic maxInstances and monitorChangesTo features Increase InstanceMaxRequests value and match the value to PHP_FCGI_MAX_REQUESTS environment variable

5. PHP 5.3 PHP 5.3 improvements: Using VC9 compiler (PHP 5.2 used VC6) Optimized API calls (using Win32 instead of POSIX) All PHP libraries built from the source code Compatibility fixes Windows builds are available at: http://windows.php.net/ From: http://ilia.ws/files/Confoo2010_PHP53.pdf “Substantial performance improvements on Windows (40% +)”

6. WinCache 1.0 PHP Accelerator optimized for Windows Opcode cache File cache Resolve path cache Download from: http://www.iis.net/expand/WinCacheForPhp Contributed by MS to PECL: Source code on http://pecl.php.net/wincache/ Documentation on http://www.php.net/wincache/ BSD license Contributions are welcome!

7. Why use opcode cache? To serve index.php in WordPress, PHP has to read, parse, compileand execute more than 100 php files!

8. WinCache 1.0 Useful Tips: Increase maxInstances or use dynamic maxInstances Adjust file cache and opcode cache sizes. Use wincache.php to study cache usage Keep wincache.chkinterval value high on production servers and low on development machines Restrict access to wincache.php by using built-inauthentication or web server authentication

9. WinCache 1.1 Beta2 released in April 2010 Object cache – Compatible with APC APIs WinCache session handler File change notification support Function hooks Useful Tips: Turn on user cache if application supports it Port from existing code which uses APC’s object cache Keep file change notification turned on Turn on session handler if not running a web farm

10. SQL Server Driver for PHP Thin layer over SNAC (ODBC) Single functional layer with thin API layer on top SQL Server Driver for PHP 1.1 SQL Server Driver for PHP 2.0 php_sqlsrv.dll php_pdo_sqlsrv.dll php_sqlsrv.dll PDO API SQLSRV Native API SQLSRV Native API Core Functional Layer SQL Server Native Client (ODBC)

11. SQL Server Driver for PHP Tips Scrollable Cursor: scrollable but slower Use sqlsrv_has_rows() w/ CURSOR_FORWARD if you only need to check if there’s data in the resultset, it’s faster and doesn’t move the cursor If scrollable required, consider CURSOR_STATIC first WarningsReturnAsErrors: ON by default Remember to turn it OFF in deployment Should we change default to OFF? UTF-8 encoding The default for PDO, available per col/param Should we make this the default for sqlsrv_xxx? Use transactions for DDL to improve performance

12. SQL Server Query Tips Range query: SELECT * FROM table ORDER BY date LIMIT 20,10 Use TOP & ROW_NUMBER SELECT sub2.*,ROW_NUMBER() OVER(ORDER BY sub2._l2) AS _lFROM ( SELECT 1 AS _l2, sub1.* FROM ( SELECT TOP(30) * FROM table ORDER BY date ) AS sub1) as sub2WHERE _l BETWEEN 20 AND 30; SELECT * FROM ( SELECT *, ROW_NUMBER() OVER(ORDER BY date) AS _l FROM table ) AS t WHERE _l BETWEEN 20 AND 30 ORDER BY _l;

13. Web Platform Installer Easy way to install IIS components, PHP 5.2, PHP and Asp.Net web applications etc. Demo PHP 5.3 will be offered through WebPI soon

14. Community participation WinCache is on PECL and SQL driver for PHP is on codeplex IIS and WinCache documentation on php.net Participating on PHP newsgroups Working with PHP developers to improve PHP and PHP installer Working with PHP application developers to integrate URLRewrite, WinCache

15. Miscellaneous tips Set IP address of MySql machine in hosts file Build PHP yourself and statically link WinCache Compile and optimize using PGO for maximum performance URLRewrite Includes htaccess importer Use IIS warm-up module to fill opcode cache before first request arrives

16. What is Windows Azure? It’s an Operating System In the Cloud. Simple Answer? Windows Azure: operating system as an online serviceMicrosoft SQL Azure: fully relational cloud database solutionWindows Azure platform AppFabric: connects cloud services and on-premises applicationsMicrosoft Codename “Dallas”: information marketplace for data and web services
