PHP网站制作之PHP读取设置文件类(php,ini,yaml,xml) - 仓酷云

<?phpclassSettings{var$_settings=array();functionget($var){$var=explode(.,$var);$result=$this->_settings;foreach($varas$key){if(!isset($result[$key])){returnfalse;}$result=$result[$key];}return$result;}functionload(){trigger_error(Notyetimplemented,E_USER_ERROR);}}classSettings_PHPextendsSettings{functionload($file){if(file_exists($file)==false){returnfalse;}//Includefileinclude($file);unset($file);//Getdeclaredvariables$vars=get_defined_vars();//Addtosettingsarrayforeach($varsas$key=>$val){if($key==this)continue;$this->_settings[$key]=$val;}}}classSettings_INIextendsSettings{functionload($file){if(file_exists($file)==false){returnfalse;}$this->_settings=parse_ini_file($file,true);}}classSettings_YAMLextendsSettings{functionload($file){if(file_exists($file)==false){returnfalse;}include(spyc.php);$this->_settings=Spyc::YAMLLoad($file);}}classSettings_XMLextendsSettings{functionload($file){if(file_exists($file)==false){returnfalse;}include(xmllib.php);$xml=file_get_contents($file);$data=XML_unserialize($xml);$this->_settings=$data[settings];}}?>php/***针对PHP的设置,若有设置文件*config.php<?php$db=array();//Enteryourdatabasenamehere:$db[name]=test;//EnterthehostnameofyourMySQLserver:$db[host]=localhost;?>//详细挪用:include(settings.php);//原始情况假定每一个类为独自的一个类名.php文件//Loadsettings(PHP)$settings=newSettings_PHP;$settings->load(config.php);echoPHP:.$settings->get(db.host).;**/读取INI文件,次要用到parser_ini_file函数,该函数前往一个数组,如第二个参数为true时则前往多维数组/***ini例子:config.ini*[db]name=testhost=localhost//挪用例子:$settings=newSettings_INI;$settings->load(config.ini);echoINI:.$settings->get(db.host).;*/读取XML文件,必要用到XML_PARSER，xmllib.php在http://hudeyong926.iteye.com/admin/blogs/836048/***XML例子:config.xml<?xmlversion="1.0"encoding="UTF-8"?><settings><db><name>test</name><host>localhost</host></db></settings>//Loadsettings(XML)$settings=NewSettings_XML;$settings->load(config.xml);echoXML:.$settings->get(db.host).;**/读取YAML格局文件,利用YAML必需利用到SPYC这个库,相干链接在http://spyc.sourceforge.net//**YAML设置例子:config.yamldb:name:testhost:localhost//Loadsettings(YAML)$settings=NewSettings_YAML;$settings->load(config.yaml);echoYAML:.$settings->get(db.host).;*/1。ini有点过期？？2。xml对照好，3。yaml很好，可是究竟没有尺度化。4。txt要本人构造格局，开放性欠好。5。类序列化。对照好，可是不熟习的人利用对照贫苦！6。php界说常量（你不必修正数据吗？）以是：xml最好。
