What is the potential issue with splitting file names in PHP using the split function?

The potential issue with splitting file names in PHP using the split function is that the function has been deprecated since PHP 5.3.0 and completely removed as of PHP 7.0.0. To solve this issue, you can use the explode function in PHP, which is more commonly used for splitting strings based on a delimiter. 

// Splitting file name using explode function
$filename = "example.txt";
$file_parts = explode(".", $filename);
$filename_without_extension = $file_parts[0];
$extension = $file_parts[1];

echo "Filename without extension: " . $filename_without_extension . "\n";
echo "Extension: " . $extension;
