How to query the absolute path in laravel (two methods)

Laravel is an excellent PHP framework that has received widespread attention and favor for its simplicity, ease of use, and high flexibility. In the process of developing applications using the Laravel framework, it is often necessary to use absolute paths to locate files and directories. This article will explore how to query absolute paths in laravel.

Laravel provides multiple ways to query absolute paths. Below we will explain them from two aspects.

Use the built-in function realpath()

The laravel framework provides a built-in function realpath() to obtain the absolute path of the current file. This function returns the absolute path name of the parameter path. If If the parameter path is a relative path, the absolute path name relative to the current working directory is returned.

$path = 'app/Http/Controllers/Controller.php';
$real_path = realpath($path);

In the above code, the absolute path of the Controller.php file is obtained by calling the realpath() function and passing in the parameter $path. In actual development, we can also obtain the absolute path of a file or directory by converting a relative path to an absolute path.

Use laravel's own auxiliary functions base_path() and app_path()

In addition to the above built-in function realpath(), laravel also provides two auxiliary functions base_path() and app_path( ) to get the application's root directory path and application directory path. Among them, base_path() returns the root directory path of the application, while app_path() returns the application directory path.

$base_path = base_path();
$app_path = app_path();

In the above code, by calling the auxiliary functions base_path() and app_path(), programmers can obtain the root directory and application directory of the laravel application. The return value can be used in subsequent file and directory operations.

Overall, the absolute path query method provided by laravel is very simple and flexible, and it is very convenient to use. Through the above two methods, we can easily obtain the absolute path of any file or directory in the laravel application, thereby achieving more convenient file and directory operations.
