1、如果一个函数可以声明为静态的，那么就用静态的，速度是改进的一个因素4。 2、# Avoid magic like __get, __set, __autoload 3、require_once() is expensive 4、Use full paths in includes and requires, less time spent on resolving the OS paths. 5、If you need to find out the time when the scrīpt started executing, $_SERVER[’REQUEST_TIME’] is preferred to time() 6、See if you can use strncasecmp, strpbrk and stripos instead of regex 7、preg_replace is faster than str_replace, but strtr is faster than preg_replace by a factor of 4 8、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. 一些函数，比如字符串替换函数，接受数组和单个字符做为参数，并且如果你的参数列表不是很长，考虑写一些冗余替换语句，每次传送一个字符，代替一行代码接受数组做为查找和替换的参数。 对于模板，你是否在用smarty?这可能是保证把最经常访问的页面缓存起来的最快的方法了。 （编辑：核心网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
