Yes. More or less.

Browsers are among the programs which do not identify files, which are
sent to them, by the filename extension, but by the so called
MIME-type. This MIME-type is not part of the file or the filename, but
an exterior description of the file. In this case, the MIME-type is
sent via the HTTP-headers.
This way, a php-script can be anything, plain-text, HTML or an image,
by just sending a header like:
header("Content-type: image/gif");
or
header("Content-type: text/plain");
Default is
header("Content-type: text/html");
If you want a list of all MIME-types or something like that, try asking
someone who knows, or google.com.
