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>";
}
?>
