I'm writing the code for a website right now that's uploads images and then displays them gallery style. What I would like to happen is for the file name of the image to be entered into the site's database as the name of the image. However, just using $_FILES['images']['name'];
gives me the file name but with the file extension attached at the end. How would I remove the file extension so I can use the file name by itself?

You can use the pathinfo()
function (docs).
$example = "my_file.jpeg";
$filename = pathinfo($example, PATHINFO_FILENAME);
echo $filename; // my_file

Just use preg_replace:
$name = preg_replace('/(.+)\.\w+$/U', $_FILES['images']['name'], '$1');

You can use rename
to remove the extension:

As my comment above implies, it depends on what you consider in the filename to be the name and what is the extension.
everything up to the last dot:
$filename = 'some.file.name.zip';
$name = substr($filename, 0, strrpos($filename, '.'));
everything up to the first dot:
$filename = 'some.file.name.zip';
$name = substr($filename, 0, strpos($filename, '.'));
they look the same, but the first one looks for the first dot from the end of the string and the second one from the start of the string.
