首页 / 网页编程 / PHP / 再次研究下cache_lite
晚上详细的看了下cache_lite,功能比我想象中的强大的多。当然目前我还没有发现它是否支持直接保存PHP代码来缓存的功能,不过我想应该是可以扩展实现的。 这里有几个例子:<? require_once( "../libs/cache/Lite.php" ); $options = array( "cacheDir" => "../cache/test/" , "fileLocking" => true , "writeControl" => true , "readControl" => false , "fileNameProtection" => false , //关闭文件名安全模式。cache id和组名将直接应用到 cache文件的文件名,所以要小心使用特殊字符. "automaticSerialization" => false , //关闭自动序列 "hashedDirectoryLevel" => 2 , //设置两级缓存路径 "lifeTime" => 60 ); $Cache = new Cache_Lite ( $options ); $id = "test" ; if( $data = $Cache -> get ( $id , "test" )){ echo $data ; }else{ $data = time (); $Cache -> save ( $data ); echo $data ; } ?> 对输出进行缓存<? require_once( "../libs/cache/Lite.php" ); require_once( "../libs/cache/Lite/output.php" ); $options = array( "cacheDir" => "../cache/test/" , "lifeTime" => 60 , "pearErrorMode" => CACHE_LITE_ERROR_DIE ); $cache =new Cache_Lite_Output ( $options ); if (!( $cache -> start ( "id_of_the_page" ))) { // 没有发现Cache ! echo "test time:" . time (). "<br>test<br>" ; $cache -> end (); // 缓冲的输出现在被存储到一个cache文件中 } ?> 对函数进行缓存<? require_once( "../libs/cache/Lite.php" ); require_once( "../libs/cache/Lite/Function.php" ); $options = array( "cacheDir" => "../cache/test/" , "lifeTime" => 3600 , "pearErrorMode" => CACHE_LITE_ERROR_DIE ); $cache = new Cache_Lite_Function ( $options ); $cache -> call ( "function_to_bench" , 12 , 45 ); function function_to_bench ( $arg1 , $arg2 ) { echo "This is the output of the function function_to_bench($arg1, $arg2) !<br>" ; return "This is the result of the function function_to_bench($arg1, $arg2) !<br>" ; } ?>
