一个简单的cache示例不过太简单了一些
// 首先创建"cache"目录 ,用来写文件 function BZ_cache ($url,$cacheName) { global $cache ; global $QUERY_STRING ; // 这里你可以按自己的习惯命名 $filename = "cache/".$cacheName.",".$QUERY_STRING.".html" ; // 这里你还应该测试一下文件的时间,看是否过期 //(不过这里没做。呵呵!自己完成吧!) if ( file_exists ( $filename) ) { readfile ($filename) ; return 1 ; /// Ok iv send the html page } else { if ( ! isset ($cache ) ) { $fcontents = join (, file ($url."?".$QUERY_STRING."&cache=t")); $fp = fopen ($filename , "w"); fwrite ($fp, $fcontents ); fclose ( $fp) ; return 0 ; /// iv to execute the file } } } // 在你的PHP文件的最开始放入下面一行代码 // if ( BZ_cache ("COMPLETE URL WITHOUT PARAMS" , "AN_IDENTIFIER" ) ) exit () ; //记住,这个URL是要完全的,即前面要有http://。但后面不要参数。 // 网上有一个例子:http://azerclic.labynet.org/doc.php3 // 第一行是 // if ( BZ_cache ("http://azerclic.labynet.org/doc.php3" , "doc" ) ) exit () ; // 你会看到cached文件在 http://azerclic.labynet.org/cache/ // Thats all //好运! //我估计在WIN32下没问题,在LINUX下还要考虑权限问题的,因为一般都没有写权限。
