Summary

In this chapter we've looked deeply into optimizing PHP code.

We've suggested a methodology for optimizing code based on:

• Profiling

• Analysis of script profiles

• Optimization of bottlenecks

Then we looked into several different optimization approaches like:

• Optimizing code

• Optimizing the database

• Buffering output

• Caching

While PHP programmers are proud of the "speed of coding" concept, the "speed of code" goal may appear. So PHP programmers should be aware of optimization techniques.
