HP is a very fast programming language, but there is more to optimizing PHP than just speed of code execution.

In this chapter, we explain why optimizing PHP involves many factors which are not code related, and why tuning PHP requires an understanding of how PHP performs in relation to all the other subsystems on your server, and then identifying bottlenecks caused by these subsystems and fixing them. We also cover how to tune and optimize your PHP scripts so they run even faster.

ADOdb is a database abstraction library for PHP. There is also a Python version; see the ADOdb for Python docs.

The PHP version currently supports an amazing number of databases, thanks to the wonderful ADOdb community: MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Foxpro, Access, ADO, Sybase, FrontBase, DB2, SAP DB, SQLite, Netezza, LDAP, and generic ODBC, ODBTP. The Sybase, Informix, FrontBase and PostgreSQL, Netezza, LDAP, ODBTP drivers are community contributions. Here is the complete list of drivers.

You write good code. But things can happen. How fast can you spot Rails performance problems—and their root causes? Don't rely on log files to solve tough performance problems. With New Relic RPM, you see problems in real-time, drill down to find the causes, fix them, and feel good again. You'll find the slowest ActiveRecord queries and slowest controllers. You'll trace transactions in fine detail. You'll see exactly where your app spends the most time. Monitor from development to production.

If you are trying to access a SOAP service from behind a firewall and your SOAP library does not have support for proxying network connections, you may not be able to get through by direct request. In such cases, you can use socket redirection programs to make the connection through a proxy server. Uche Ogbuji shows how to do so in this tip.
