40 Tips for optimizing your php Code - reinholdweber.com

| reinholdweber.com | 40 Tips for optimizing your php Code

| 1. If a method can be static, declare it static. Speed improvement is by a factor of 4. | 2. echo is faster than print. | 3. Use echo's multiple parameters instead of string concatenation. | 4. Set the maxvalue for your for-loops before and not in the loop. | 5. Unset your variables to free memory, especially large arrays. | 6. Avoid magic like __get, __set, __autoload | 7. require_once() is expensive | 8. Use full paths in includes and requires, less time spent on resolving the OS paths. | 9. If you need to find out the time when the script started executing, $_SERVER[‘REQUEST_TIME’] is preferred to time() | 10. See if you can use strncasecmp, strpbrk and stripos instead of regex | 11. str_replace is faster than preg_replace, but strtr is faster than str_replace by a factor of 4 | 12. If the function, such as string replacement function, accepts both arrays and single characters as arguments, and if your argument list is not too long, consider writing a few redundant replacement statements, passing one character at a time, instead of one line of code that accepts arrays as search and replace arguments. | 13. It's better to use select statements than multi if, else if, statements. | 14. Error suppression with @ is very slow. | 15. Turn on apache's mod_deflate | 16. Close your database connections when you're done with them | 17. $row[‘id’] is 7 times faster than $row[id] | 18. Error messages are expensive | 19. Do not use functions inside of for loop, such as for ($x=0; $x < count($array); $x) The count() function gets called each time. | 20. Incrementing a local variable in a method is the fastest. Nearly the same as calling a local variable in a function.
