How to find the path of deleted files in php

When performing a PHP file deletion operation, you need to provide the file path to be deleted. Here are several ways to find file paths:

1. Absolute paths: Using absolute paths ensures that files are accurately found and deleted. Absolute paths usually start with the root directory (/) and list the full path to the file. For example, to delete the "example.jpg" file located in the "/var/www/html/uploads" directory, you can use the following statement:

unlink('/var/www/html/uploads/example.jpg');

2. Relative paths: Relative paths are based on The path calculated from the current working directory (that is, the directory where the script is located). This means that when running the script in a different directory, the relative path must be changed accordingly. For example, to delete the "example.jpg" file in the same directory, you can use the following statement:

unlink('example.jpg');

3. Dynamic path: A dynamic path is a path generated using a variable or function. In this case, using a variable or function to generate the path can easily change the file path to be deleted. For example, the following code dynamically generates a path based on the file name uploaded by the user:

$user_file = $_FILES['file']['name'];
$upload_folder = '/var/www/html/uploads/';
$filepath = $upload_folder . $user_file;
unlink($filepath);

Through these methods, you can find and delete the files you need. Please note that before performing a file deletion operation, make sure you have the correct file path and sufficient permissions to perform this operation.
