<pre><code class="html" data-trim>Subject: Announce: Personal Home Page Tools (PHP Tools)
Announcing the Personal Home Page Tools (PHP Tools) version 1.0.
These tools are a set of small tight cgi binaries written in C.
They perform a number of functions including:
. Logging accesses to your pages in your own private log files
. Real-time viewing of log information
. Providing a nice interface to this log information
. Displaying last access information right on your pages
. Full daily and total access counters
. Banning access to users based on their domain
. Password protecting pages based on users' domains
. Tracking accesses ** based on users' e-mail addresses **
. Tracking referring URL's - HTTP_REFERER support
. Performing server-side includes without needing server support for it
. Ability to not log accesses from certain domains (ie. your own)
. Easily create and display forms
. Ability to use form information in following documents
Here is what you don't need to use these tools:
. You do not need root access - install in your ~/public_html dir
. You do not need server-side includes enabled in your server
. You do not need access to Perl or Tcl or any other script interpreter
. You do not need access to the httpd log files
The only requirement for these tools to work is that you have
the ability to execute your own cgi programs. Ask your system
administrator if you are not sure what this means.
The tools also allow you to implement a guestbook or any other
form that needs to write information and display it to users
later in about 2 minutes.
The tools are in the public domain distributed under the GNU
Public License. Yes, that means they are free!
For a complete demonstration of these tools, point your browser

<h2>C API for the Web</h2>

Error("Stack error in cos");

}

Push(temp,DNUMBER);
}</code></pre>
<h4 class="p">And you could then use it like this:</h4>
<pre><code class="nohighlight" data-trim><html><head><title>Cos Example</title></head>
<body><h1>Cos Example</h1>
<?echo Cos($input)>
</body></html></code></pre>

Actually the very first markup used html comments<br />

Note the lack of the closing '?'<br />
