写了许多function和class,分别保存在若干个php文件里。
如a.php
function my_trim($text){
return strip_tags(trim($text));
}
现在有一个index.php页面,如何加载这些function和class,用include,requre_once,require,哪种耗资源最少,效率最高?
另外,如果网站支持多语言,在index.php里如何加载语言文件,语言文件的保存格式是什么?也是include,requre_once,require?如何替换function和class里的翻译文字?
回复讨论(解决方案)
include_once/require_once 不推荐使用这种习惯,推荐自行判断是否已include
include 如果出错,仍然会继续执行
require 如果出错,会产生致命错误,中止执行后面的代码
还有呢?继续给些指点吧。
