PHP如果条件带和和或

Question

我有这个条件：

if($_SERVER['REQUEST_URI'] != '/page.php' || ($_SERVER['REQUEST_URI'] != '/' && $_SERVER['REQUEST_URI'] != '/index.php')){

        //do something, but not on index or page . php

}

它适用于索引页面，但不适用于page.php ...我做错了什么？

Answer 1

你可以更轻松地做到......

if( ! in_array( $_SERVER['REQUEST_URI'], array("/page.php", "/", "/index.php") ) ) {
  // do something...
}

Answer 2

您使用逻辑错误

if(!($_SERVER['REQUEST_URI'] == '/page.php' || $_SERVER['REQUEST_URI'] == '/' || $_SERVER['REQUEST_URI'] == '/index.php')){

        //do something, but not on index or page . php
}

或更好

if(!in_array($_SERVER['REQUEST_URI'], ["/page.php", "/", "/index.php"])){

        //do something, but not on index or page . php
}
