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

Getting File Name Without Extension: A Simplified Approach

Your initial code aims to extract the file name without extension, yet it seems overly complex. A simpler solution lies in utilizing PHP's built-in function, pathinfo().

pathinfo() decomposes a file path into its various components, including the filename without extension. For example, the code snippet below demonstrates its usage:

$filename = pathinfo($filepath, PATHINFO_FILENAME);

Here, $filepath represents the file string stored in a variable. The result, $filename, will contain the filename stripped of its extension.

To illustrate further, consider the following example:

$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 since PHP 5.2.0

This code outputs the following:

/www/htdocs
index.html
html
index

As you can see, pathinfo() provides a convenient and efficient way to extract file components, including the filename without extension. It eliminates the need for complex regular expressions and offers a more straightforward approach to file manipulation tasks.
