The Right Way to Get a File Extension in PHP
I made a recent search on retrieving file extensions in PHP.
I found out that a lot have been re-inventing the wheel. They have been creating code for functionality that PHP already has. This is one example of re-inventing the wheel
function get_file_extension($file_name)
{
return substr(strrchr($file_name,'.'),1);
}
Another example was this:
function file_extension($filename)
{
return end(explode(".", $filename));
}
PHP already has a function that does the same thing and more.
