What is MIME type?

A MIME type (also known as a media type or content type) is a string identifier that specifies the format of a file. It is used by web browsers and other software to determine how to handle the file when it is received.

The format of a MIME type is "type/subtype", where "type" is a general category of the file (such as "text", "image", or "audio"), and "subtype" is a more specific identifier (such as "plain" for text files or "jpeg" for image files).

For example, the MIME type "text/plain" is used for plain text files, and the MIME type "image/jpeg" is used for JPEG image files.

How To check MIME Type

There are several ways to check the MIME type of a file, depending on the context and the tools available. Some common methods include:

Using The file Command

On Linux and macOS systems, you can use the file command in the terminal to check the MIME type of a file. For example, "file --mime-type file.txt" will return "text/plain" for a plain text file.

Using The PHP Info Class

In PHP, you can use the info function to check the MIME type of a file. fileinfo();
