Well, I decided to give it a try.
Here's the original test webpage:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>PHP Witchcraft</title>
</head>
<body>
<p>Let's try casting a spell....</p>
</body>
</html>
Here's the result after the conversion:
<?php
echo "<!-- Please register VisorSoft HTML To PHP Converter 4 -->\n";
echo "<H3><FONT COLOR=\"#FF0000\">This PHP file was generated using an UNREGISTERED COPY of <a href=\"http://www.visorsoft.com\">VisorSoft Software HTML To PHP Converter 4</a><br>The registered version does not display this notice.</FONT></H3>\n";
echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"\n";
echo " \"http://www.w3.org/TR/html4/loose.dtd\">\n";
echo "<html>\n";
echo "<head>\n";
echo "<title>PHP Witchcraft</title>\n";
echo "</head>\n";
echo "<body>\n";
echo "<p>Let's try casting a spell....</p>\n";
echo "</body>\n";
echo "</html>\n";
echo "<!-- Please register VisorSoft HTML To PHP Converter 4 -->\n";
echo "<H3><FONT COLOR=\"#FF0000\">This PHP file was generated using an UNREGISTERED COPY of <a href=\"http://www.visorsoft.com\">VisorSoft Software HTML To PHP Converter 4</a><br>The registered version does not display this notice.</FONT></H3>\n";
?>
It seems that in single file mode one has to actually provide an existing PHP file to which the converted text can be written. Multiple file mode simply creates a PHP file with the same name, but different extension.
The program settings are not too complicated. A pair of radio buttons to choose if you want a sound to be played on conversion, and a text input control to choose the location of the sound file.
As for the PHP code generated... well, +1 for the avoidance of short tags. I do not really know why one would want to step into PHP in the first place, but I guess that VisorSoft's customers know better.
I tested the uninstall, and it seems to work. Oh well.
