看到一段代码是这样写的
$site_url = strtolower('http://'.$_SERVER['HTTP_HOST'].substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'], '/index.php')).'/shop/index.php');
然后我试了一下,
其实把红色部分去掉也是一样,但我不明白他为啥要脱裤子放屁呢
$site_url = strtolower('http://'.$_SERVER['HTTP_HOST']. substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'], '/index.php')).'/shop/index.php');


回复讨论(解决方案)

这个可以不要。


不知道你是从哪里看到的代码,也不知道其真实的目的
但绝不是“脱裤子放屁”的问题
去掉了就是这样

怎么能说是一样的呢?
