View the source of your browser. Is it showing the SVG code? You need to
output the correct mime-type headers for the SVG, as by default, PHP
outputs headers for HTML. Something like this should do the trick:
header("Content-type: image/svg+xml");
This has to occur before any output has already been sent to the
browser, otherwise you'll get a headers already sent error.
