How Can I Extract a Filename from a Full Path in PHP?

Extracting File Names from Paths in PHP

In PHP, the need often arises to retrieve the file name from a full path, particularly when working with directories or manipulating file systems. Let's explore how to achieve this using PHP's powerful functions.

Problem: Retrieving File Name from Full Path

Suppose we have the following full path:

F:Program FilesSSH Communications SecuritySSH Secure ShellOutput.map

And we wish to extract the file name, which is "Output.map."

Solution: Using basename() function

The PHP basename() function provides a concise and convenient way to retrieve the file name from a given path.

Syntax:

basename(path, suffix)

Parameters:

• path: The full path from which to extract the file name.
• suffix (optional): If provided, removes the specified suffix from the file name.

Example:

To extract the file name from our example path:

<?php
$path = "F:\Program Files\SSH Communications Security\SSH Secure Shell\Output.map";
$file_name = basename($path);
echo $file_name; // Output: Output.map
?>

Removing File Extension:

The suffix parameter can be used to remove any file extension from the retrieved file name. For instance, to extract "Output" from "Output.map":

<?php
$path = "F:\Program Files\SSH Communications Security\SSH Secure Shell\Output.map";
$file_name_without_extension = basename($path, ".map");
echo $file_name_without_extension; // Output: Output
?>

By leveraging PHP's basename() function, developers can efficiently extract file names from full paths with ease and flexibility. This capability is especially useful in a wide range of file management and manipulation scenarios.
