Snippet of PHP code to hide "Page Title" at top of Dashboard Editor

Hi

Can anyone help with a piece of PHP code to hide the "Page Title" in the Dashboard Editor, please?

That is the oblong box at the top of the TnyMCE Page Editor Page [in the Dashboard] where admin usually enters and changes the Page Title?

A piece of code I could put in a Themes Function.PHP file?

Thanking you in advance.
Regards
