Include () with reference transfer instance in php

Include is a function that calls files in php. By default, it cannot be like include (a. php? Id = 1) in this case, the following describes how to solve the problem of using include without parameters.

Sometimes, based on some special requirements, you need to use the include () method in PHP to call a file that independently provides services in the project. If the called file uses the GET method to import data, you need some tips.

For example, suppose that inc. php needs to be called in index. php? Para = 3,

Inc. php

The Code is as follows: Copy code

<? Php echo $ _ GET ['para'];?>

The following statement cannot produce the correct result:
Index. php

The Code is as follows: Copy code


<? Php include dirname (_ FILE _). '/inc. php? Para = 3';?>

With a slight flexibility, you can define the $ _ GET variable before include to run normally:
Index. php

 

The Code is as follows: Copy code
<? Php
$ _ GET ['para'] = 3;
Include dirname (_ FILE _). '/inc. php;?>

If the allow_url_include function is enabled in php. ini, you can use the include url method:
Index. php

The Code is as follows: Copy code


<? Php include 'HTTP: // www.yoururl.com/inc.php? Para = 3';?>

Setting Method: in php. ini, find the following line and change it to On:

The Code is as follows: Copy code

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

However, to ensure security, most servers disable the allow_url_include function.
