How to list only XML files in a directory using PHP?

Listing Specific Files in a Directory in PHP

The provided code successfully lists all files within a directory. However, to refine this list to include only files with a ".xml" or ".XML" extension, we can leverage PHP's glob() function.

glob() Function

The glob() function searches a directory for files matching a specified pattern and returns an array of the matching files. Its syntax is:

glob(pattern, flags)

where:

• pattern is the pattern to match against the files' names
• flags are optional modifiers that can affect the search

Matching XML Files

To list only XML files, we can use the glob() function as follows:

$files = glob('/path/to/dir/*.xml');

This pattern matches all files in the directory "/path/to/dir/" that end with ".xml". To include uppercase extensions as well, we can use:

$files = glob('/path/to/dir/*.{xml,XML}');

The resulting $files array will contain the paths to all matching XML files. You can then process or display these files as needed.
