okay, this is going to sound like a really dumb question, but i'm asking because it's one of those things that are like a needle in a haystack to try to find in a manual. i looked at the syntax for escaping html, but it's not covered there. i'm sure i probably learned this rule way back during the fundamentals, but i don't have anyone to quickly reference nearby, so i'm exposing my silliness here for you all to see.
if i want to embed a bit of php in an otherwise html filled page, must i use the extension .php, or will the php be parsed simply by way of using the code-embedding technique as in the following example (i know the example below will work, because i've just tested it, if the filename is filename.php):
filename.htm
<html>
<body>
lots of text
</body>
</html>
<?php
phpcode()
?>
<html>
<body>
rest of the html
</body>
</html>
i'm asking because i have used, specifically, the filename "guitar.htm", for so many years that i'd like to keep that filename for those who only have that URL (my business cards, etc).
i realize i could use a URL redirect, such as the only one i know:
<meta http-equiv="refresh" content="0; url=http://www.sonamusic.com/newsframe.htm">
is that my best option here? if so, is there a shorthand, or cleaner version of a redirect i should be using?
