PHP basename() Function: Get File or Directory Name

The 'basename()' function in PHP is used to get the base name of a file or directory from a given path. It returns the trailing name component of the path, which is the file or directory name without the path information.

Here is an example usage of the 'basename()' function:

$path = '/path/to/file.txt';
$filename = basename($path);
echo $filename; // Output: file.txt

In this example, the 'basename()' function returns the file name 'file.txt' from the given path '/path/to/file.txt'.
