How Can I Get a Filename Without Its Extension in PHP?

Getting File Name Without Extension in PHP: An Alternative Approach

Problem:

You have a PHP function that returns the file extension, but you want to modify it to return the filename without the extension.

Function Code:

function ShowFileExtension($filepath)
{
    // Code to extract filename and extension
}

Desired Result:

If the file is "my.zip", the function should return "my" (without the extension).

Solution:

There's a simpler and more efficient way to get the filename without the extension using the pathinfo() function:

$filename = pathinfo($filepath, PATHINFO_FILENAME);

The pathinfo() function breaks down a file path into its various components:

• PATHINFO_DIRNAME - the directory part
• PATHINFO_BASENAME - the basename (filename with extension)
• PATHINFO_EXTENSION - the file extension
• PATHINFO_FILENAME - the filename without extension (available in PHP 5.2.0 and higher)

Therefore, to get the filename without the extension, you simply use PATHINFO_FILENAME.
