Usage of the set_include_path function in php:

The set_include_path function in php can be used to set the application directory. When developing a project, you can apply these functions properly. This not only eliminates the need for a layer-by-layer computing directory during include, it can also improve the development efficiency and reduce the file inclusion error rate.

For example:

Resume two PHP files, one directory

The location structure is as follows:

/Index. php

/Include/config. php

Index. php:

Set_include_path ("include ");

Include ("config. php ");

?>

/Include/config. php

Reference content is as follows:

I'm config. php under include.

Now we run index. php

Why? No results?

We can include the/inlcude/config. php file only by writing config. php during include.

Separate multiple include directories ";"

For example, set_include_path ("include; include2; include3; lib; c: \ php \ lib ");

You can use relative paths or sleep paths.

Maybe you may not feel the benefits of set_include_path in this small code, but it doesn't matter. You just need to remember that this code can implement this function. In the future, the technology will be improved, don't forget to have such a function when you start to develop large projects. It can reduce your workload.

The sister function get_include_path () can obtain the include directory at that time,

Set_include_path has the same functions as our powerful and cute ini_set ()

Usage:

Ini_set ('include _ path', 'Directory name ');
