How Can I Easily Extract Filenames Without Extensions in PHP?

Extracting Filenames Without Extensions Made Easy with pathinfo()

Getting a filename without its extension in PHP can be a tedious task, especially if you rely on complex regex patterns. But there's a simpler and more efficient way to do it using the powerful pathinfo() function.

The pathinfo() function provides a comprehensive way to parse a file path into its individual components, including the filename, extension, directory, and more. To extract the filename without the extension, simply use the following code:

$filename = pathinfo($filepath, PATHINFO_FILENAME);

For example, if $filepath contains the value /var/www/my_file.txt, the above code will assign my_file to the $filename variable.

Here are some additional examples from the PHP manual:

$path_parts = pathinfo('/www/htdocs/index.html');

echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n";
echo $path_parts['filename'], "\n"; // filename is only available since PHP 5.2.0

// Output:
/www/htdocs
index.html
html
index

You can also use the pathinfo() function to extract only specific parts of the file path. For instance, to get only the extension, use this code:

$extension = pathinfo($filepath, PATHINFO_EXTENSION); // outputs 'txt'

So, next time you need to get a filename without its extension in PHP, remember the pathinfo() function. It's an elegant and efficient way to parse file paths into their individual components.
