Why cant I save file a .php?

[JLEW700]

Every time i try to save a file as .php in textedit, it says: "You cannot save this document with extension “.php” at the end of the name. The required extension is “.rtf”." How can I make it so that it alows me to save a file as .php?

Go into the text edit preferences and change the radio button from Rich Text to Plain Text.
