php Get the url of the current script_PHP tutorial

Regarding using php to obtain the URL of the current script, many friends will say that it is very simple, but to obtain very detailed information, you need to go through multiple judgments.

$PHP_TIME = time();
$PHP_SELF = isset($_SERVER['PHP_SELF']) ? $_SERVER['PHP_SELF'] : (isset($_SERVER['SCRIPT_NAME']) ? $_SERVER['SCRIPT_NAME'] : $_SERVER['ORIG_PATH_INFO']) ;

/**
获取当前运行的脚本名: 　刚开始看是不是有点乱呢。　咋没用if else 呢。 看这样的东西。我们最好从右看到左。这样比较好明白点。$_SERVER['SCRIPT_NAME'] $_SERVER['PHP_SELF']  $_SERVER['ORIG_PATH_INFO'] 这三个服务器全局变量都是获取　当前脚本名的。主要看服务器当前环境了。那个存在的就获取那个。
isset() 函数　十分有用。　测试一个变量是否已经定义。　注：　$a= NULL ; isset($a) 这样会返回false的哦。　注意　isset 和empty 两个函数的用法。用得不好会出大问题的。自己看手册。

$PHP_QUERYSTRING = $_SERVER['QUERY_STRING'];
