Functions

getMimeType()

Detects the MIME type of a file using the `finfo` extension.

getMimeType(string $file) : string|null

This is the low-level primitive shared by the higher-level MIME helpers (hasMimeType(), getImageMimeType(), tarFileInfo(), zipFileInfo()). It returns the raw type reported by finfo (e.g. text/plain, application/zip) without any normalization.

The function never throws: it returns null when the path is not a file or when detection fails (including an empty result), so callers can decide how to react (a boolean check, a fallback label such as 'unknown', etc.).

Parameters
$file : string

Path to the file to inspect.
