How to Extract a Filename Without Its Extension (Accurate Method)?

Retrieve Filename Without Extension (Accurate Method)

Many online scripts for removing file extensions rely on the presence of a dot in the filename. However, this method can lead to incorrect results, particularly for filenames with multiple dots.

A more accurate approach involves using PHP's pathinfo() function, which provides comprehensive file path information.

<code class="php"><?php
$filename = 'filename.md.txt';

// Extract the filename without the extension
$filenameWithoutExtension = pathinfo($filename, PATHINFO_FILENAME);

// Display the result
echo "Filename without extension: $filenameWithoutExtension"; // Output: filename.md
?></code>

pathinfo() returns a named array containing file path information, and passing PATHINFO_FILENAME as the second parameter returns the filename without the extension. This method accurately handles files with multiple dots and ensures that only the actual extension is removed.
