php重构优化一例——模板方法模式应用

 最近优化php项目，记录下经验，直接上干活。。。

        php在公司项目中主要用于页面展现，前端有个view，view向后端的service请求数据，数据的传输格式是json。下面看优化前的service的代码：

[php]
<?php 
require_once('../../../global.php'); 
require_once(INCLUDE_PATH . '/discache/CacherManager.php'); 
require_once(INCLUDE_PATH.'/oracle_oci.php'); 
require_once(INCLUDE_PATH.'/caihui/cwsd.php'); 
header('Content-type: text/plain; charset=utf-8'); 
$max_age = isset($_GET['max-age']) ? $_GET['max-age']*1 : 15*60; 
if($max_age < 30) { 
    $max_age = 30; 
} 
header('Cache-Control: max-age='.$max_age); 
// 通过将url进行hash作为缓冲key 
$url = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; 
$url_hash = md5($url); 
//echo "/finance/hs/marketdata/segment/${url_hash}.json"; 
if (!CacherManager::cachePageStart(CACHER_MONGO, "/finance/hs/marketdata/segment/${url_hash}.json", 60*60)) { 
 
// 查询条件 
$page = isset($_GET['page']) ? $_GET['page']*1 : 0; 
$count = isset($_GET['count']) ? $_GET['count']*1 : 30; 
$type = isset($_GET['type']) ? $_GET['type'] : 'query'; 
$sort = isset($_GET['sort']) ? $_GET['sort'] : 'symbol'; 
$order = isset($_GET['order']) ? $_GET['order'] : 'desc'; 
$callback = isset($_GET['callback']) ? $_GET['callback'] : null; 
$fieldsstring = isset($_GET['fields']) ? $_GET['fields'] : null; 
$querystring = isset($_GET['query']) ? $_GET['query'] : null; 
$symbol=isset($_GET['symbol'])?$_GET['symbol']:''; 
$date=isset($_GET['date'])?$_GET['date']:''; 
 
if ($type == 'query') { 
    $queryObj = preg_split('/:|;/', $querystring, -1); 
    for($i=0; $i<count($queryObj); $i=$i+2){ 
        if(emptyempty($queryObj[$i])) continue; 
        if($queryObj[$i]=='symbol'){ 
            $symbol = $queryObj[$i+1]; 
        } 
        if($queryObj[$i]=='date'){ 
            $date = $queryObj[$i+1]; 
        } 
    } 
}  
 
// 查询列表 
$oci = ntes_get_caihui_oci();
