I'm looking for a small function that allows me to remove the extension from a filename.
I've found many examples by googling, but they are bad, because they just remove part of the string with "." . They use dot for limiter and just cut string.
Look at these scripts,
$from = preg_replace('/.[^.]+$/','',$from);
$from=substr($from, 0, (strlen ($from)) - (strlen (strrchr($filename,'.'))));
When we add the string like this:
This.is example of somestring
It will return only "This"...
The extension can have 3 or 4 characters, so we have to check if dot is on 4 or 5 position, and then remove it.
How can it be done?
Try this one:
So, this matches a dot followed by three or four characters which are not a dot or a space. The "3 or 4" rule should probably be relaxed, since there are plenty of file extensions which are shorter or longer.
