Question

Dreamweaver can't save php file.

The error message says:

The document's current encoding can not correctly save all the characters within the document you may want to change it to UTF-8 or an encoding that support spacial characters in this document.

How can I save the file to run?

Open the file in Dreamweaver, I have CS5. Modify --> Page Properties --> Title/Encoding , use the Encoding DD to change it to UTF-8.
