Answer 1

You can use the pathinfo() function (docs).

$example  = "my_file.jpeg";
$filename = pathinfo($example, PATHINFO_FILENAME);
echo $filename; // my_file

Answer 2

You can use rename to remove the extension:

Answer 3

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.

Answer 4

Just use preg_replace:

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