PHP performance

Question

What can I do to increase the performance/speed of my PHP scripts without installing software on my servers?

Answer 1

The ones I can think of...

• Loop invariants are always a good one to watch.

• Write E_STRICT and E_NOTICE compliant code, particularly if you are logging errors.

• Avoid the @ operator.

• Absolute paths for requires and includes.

• Use strpos, str_replace etc. instead of regular expressions whenever possible.

Then there's a bunch of other methods that might work, but probably wont give you much benefit.
