# If a method can be static, declare it static. Speed improvement is by a factor of 4.

# echo is faster than print.

# Use echo’s multiple parameters instead of string concatenation.

# Set the maxvalue for your for-loops before and not in the loop.

# Unset your variables to free memory, especially large arrays.

# Avoid magic like __get, __set, __autoload

# require_once() is expensive

# Use full paths in includes and requires, less time spent on resolving the OS paths.

# If you need to find out the time when the script started executing, $_SERVER[’REQUEST_TIME’] is preferred to time()

# See if you can use strncasecmp, strpbrk and stripos instead of regex
