php中include()带参考传递实例

include php transfer function Example bring document yes of transfer default

include是php中的一个调用文件的函数,默认状态下是不可以直接像include(a.php?id=1)这样操作,下面我来介绍解决include不能带参数调用解决办法。

有时基于某些特殊需求,需要在PHP中使用include()方法调用项目中某个独立提供服务的文件,如果被调用文件使用GET方式传入数据,则需要用到一些小技巧。

举例:假设在 index.php 中需要调用 inc.php?para=3 ,

inc.php

 代码如下 复制代码

下面的写法是无法得到正确结果的:
index.php

 代码如下 复制代码


 

稍微变通一下,把$_GET变量在include之前定义,则可以正常运行:
index.php

 

 代码如下 复制代码
$_GET['para'] = 3;    
include dirname(__FILE__).'/inc.php; ?>

如果php.ini中开启了allow_url_include功能,则可以使用include url的方式:
index.php

 代码如下 复制代码


设置方法:php.ini中,找到如下行,改为On:

 代码如下 复制代码

; Whether to allow include/require to open URLs (like http:// or ftp://) as files.
allow_url_include = On

不过为了保证安全性,大部分的服务器都将allow_url_include 功能关闭,那样就只能视情况而定了。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1.

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
