[Resolved] Filenames from a directory

limeonade

When I read a filename from a directory I get filename.txt. Is there an easy way for me to strip of the .txt part?

Well, several ways, I guess. You could use [man]substr/man, maybe [man]strtok/man, probably others. [man]explode/man has a nice ring to it. How 'bout:

$filename="foo.txt";
$bomb=explode(".", $filename);
$newname=$bomb[0];

Might be expensive, though. I don't know much about large structures...

does exploding give me 2 strings then?
i.e. bomb[0]=foo and bomb[1]=txt?

Yup. 😉

Smart newbie! 😃

$filename = 'foo.txt';
echo basename($filename, '.txt'); // outputs "foo"

Hey that was just the thing devinemke, thanks.

And thanks for your help too dalecosp.
I had just written out my own function:

function getname($filename) {
	$index = strrpos($filename, ".");
	$string=substr($filename, 0, $index);
	return $string;
}

but I guess it had already been invented :rolleyes: oh well.

Thank you both.

Sure, but suppose we have a list of files like:

foo.txt
bar.gif
baz.exe
qux.file
quux.c
garply.this.is.a.long.unix.thing.here

We'd have to parse the filename somehow in order to get a suffix to feed to basename, so you end up using strtok or substr or something anyway ...

explode's pretty easy. The canonical algorithm would be a lil' more like what limeonade has already done in the function ...

... like I said, "smart newbie!"

BTW, I'm just kidding there ... nothing personal. 🙂
