Copy code The code is as follows:
function getsiteurl()
{
global $_SCONFIG;
if(empty($_SCONFIG['siteallurl']))
{
$uri = $_SERVER['REQUEST_URI'] ?$_SERVER['REQUEST_URI']:($_SERVER['PHP_SELF']?$_SERVER['PHP_SELF']:$_SERVER['SCRIPT_NAME']);
return shtmlspecialchars('http://'.$_SERVER[' HTTP_HOST'].substr($uri, 0, strrpos($uri, '/')+1));
}
else
{
return $_SCONFIG['siteallurl'];
}
}
global $ _SCONFIG; //Define the global variable $_SCONFIG ($_SCONFIG is actually an array var, defined in common.php)
if(empty($_SCONFIG['siteallurl'])) //Judge the $_SCONFIG['siteallurl'] variable Is it empty? $uri = $_SERVER['REQUEST_URI']?$_SERVER['REQUEST_URI']:($_SERVER['PHP_SELF']?$_SERVER['PHP_SELF']:$_SERVER['SCRIPT_NAME']);
//Put $_SERVER['REQUEST_URI'];$_SERVER['PHP_SELF'];$_SERVER['SCRIPT_NAME'] through ternary operation and give the result to $url
//$_SERVER is also an array, you can print it, just You know what it is used for. Only three array elements are involved here
//$_SERVER['REQUEST_URI']; //REQUEST_URI:/mysite/->Site directory?
//$_SERVER['PHP_SELF']; / /PHP_SELF:/mysite/index.php->The file name of the currently executing script
//$_SERVER['SCRIPT_NAME']; //SCRIPT_NAME:/mysite/index.php->The path containing the current script
The above introduces the hummell gets the rockets php getsiteurl function, including the content of hummell gets the rockets. I hope it will be helpful to friends who are interested in PHP tutorials.
