php獲取當前頁面完整URL地址函數，希望對你們有所幫助，代碼如下：

/**

* 獲取當前頁面完整URL地址

*/

function get_url() {

$sys_protocal = isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443' ? 'https://' : 'http://';

$php_self = $_SERVER['PHP_SELF'] ? safe_replace($_SERVER['PHP_SELF']) : safe_replace($_SERVER['SCRIPT_NAME']);

$path_info = isset($_SERVER['PATH_INFO']) ? safe_replace($_SERVER['PATH_INFO']) : '';

$relate_url = isset($_SERVER['REQUEST_URI']) ? safe_replace($_SERVER['REQUEST_URI']) : $php_self.(isset($_SERVER['QUERY_STRING']) ? '?'.safe_replace($_SERVER['QUERY_STRING']) : $path_info);

return $sys_protocal.(isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : '').$relate_url;

}
