A Few Tips for Speeding Up PHP Code - Conclusion

(Page 5 of 5 )

I manipulate information pulled from a database on a daily basis, pushing rows around and testing for various conditions that will determine what I'm to do to my data next. Among my most commonly-used functions are those that allow me to interact with the database and those that I use to test for and modify patterns within strings. Knowing that my applications will function better on the whole if I fine-tune these frequent operations, I sought to measure their performance so that I could strive at all times to use the most efficient code. Findings in this batch of experimentation were that trimming database results prior to actually manipulating the data makes a significant difference; that batching INSERT, UPDATE, and DELETE queries rather than performing them one at a time can more than double the speed with which these queries are executed; and that the preg functions seem to be faster and more versatile for text manipulation.
