DESCRIPTION:
What is Snoopy?
Snoopy is a PHP class that simulates a web browser. It automates the
task of retrieving web page content and posting forms, for example.
Some of Snoopy's features:
* easily fetch the contents of a web page
* easily fetch the text from a web page (strip html tags)
* easily fetch the the links from a web page
* supports proxy hosts
* supports basic user/pass authentication
* supports setting user_agent, referer, cookies and header content
* supports browser redirects, and controlled depth of redirects
* expands fetched links to fully qualified URLs (default)
* easily submit form data and retrieve the results
* supports following html frames (added v0.92)
* supports passing cookies on redirects (added v0.92)
REQUIREMENTS:
Snoopy requires PHP with PCRE (Perl Compatible Regular ｅxpressions),
which should be PHP 3.0.9 and up. For read timeout support, it requires
PHP 4 Beta 4 or later. Snoopy was developed and tested with PHP 3.0.12.
CLASS METHODS:
fetch($URI)
-----------
This is the method used for fetching the contents of a web page.
$URI is the fully qualified URL of the page to fetch.
The results of the fetch are stored in $this->results.
If you are fetching frames, then $this->results
contains each frame fetched in an array.
fetchtext($URI)
---------------
This behaves exactly like fetch() except that it only returns
the text from the page, stripping out html tags and other
irrelevant data.
fetchform($URI)
---------------
This behaves exactly like fetch() except that it only returns
the form elements from the page, stripping out html tags and other
irrelevant data.
fetchlinks($URI)
----------------
This behaves exactly like fetch() except that it only returns
the links from the page. By default, relative links are
converted to their fully qualified URL form.
submit($URI,$formvars)
----------------------
This submits a form to the specified $URI. $formvars is an
array of the form variables to pass.
submittext($URI,$formvars)
--------------------------
This behaves exactly like submit() except that it only returns
the text from the page, stripping out html tags and other
irrelevant data.
submitlinks($URI)
----------------
This behaves exactly like submit() except that it only returns
the links from the page. By default, relative links are
converted to their fully qualified URL form.

EXAMPLES:
Example: fetch a web page and display the return headers and
the contents of the page (html-escaped):
include "Snoopy.class.php";
$snoopy = new Snoopy;
$snoopy->user = "joe";
$snoopy->pass = "bloe";
if($snoopy->fetch("http://www.slashdot.org/"))
{
echo "response code: ".$snoopy->response_code."<br>\n";
while(list($key,$val) = each($snoopy->headers))
echo $key.": ".$val."<br>\n";
echo "<p>\n";
echo "<PRE>".htmlspecialchars($snoopy->results)."</PRE>\n";
}
else
echo "error fetching document: ".$snoopy->error."\n";
Example: submit a form and print out the result headers
and html-escaped page:
include "Snoopy.class.php";
$snoopy = new Snoopy;
$submit_url = "http://lnk.ispi.net/texis/scripts/msearch/netsearch.html";
$submit_vars["q"] = "amiga";
$submit_vars["submit"] = "Search!";
$submit_vars["searchhost"] = "Altavista";
if($snoopy->submit($submit_url,$submit_vars))
{
while(list($key,$val) = each($snoopy->headers))
echo $key.": ".$val."<br>\n";
echo "<p>\n";
echo "<PRE>".htmlspecialchars($snoopy->results)."</PRE>\n";
}
else
echo "error fetching document: ".$snoopy->error."\n";
Example: showing functionality of all the variables:
include "Snoopy.class.php";
$snoopy = new Snoopy;
$snoopy->proxy_host = "my.proxy.host";
$snoopy->proxy_port = "8080";
$snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)";
$snoopy->referer = "http://www.microsnot.com/";
$snoopy->cookies["SessionID"] = 238472834723489l;
$snoopy->cookies["favoriteColor"] = "RED";
$snoopy->rawheaders["Pragma"] = "no-cache";
$snoopy->maxredirs = 2;
$snoopy->offsiteok = false;
$snoopy->expandlinks = false;
$snoopy->user = "joe";
$snoopy->pass = "bloe";
if($snoopy->fetchtext("http://www.phpbuilder.com"))
{
while(list($key,$val) = each($snoopy->headers))
echo $key.": ".$val."<br>\n";
echo "<p>\n";
echo "<PRE>".htmlspecialchars($snoopy->results)."</PRE>\n";
}
else
echo "error fetching document: ".$snoopy->error."\n";
Example: fetched framed content and display the results
include "Snoopy.class.php";
$snoopy = new Snoopy;
$snoopy->maxframes = 5;
if($snoopy->fetch("http://www.ispi.net/"))
{
echo "<PRE>".htmlspecialchars($snoopy->results[0])."</PRE>\n";
echo "<PRE>".htmlspecialchars($snoopy->results[1])."</PRE>\n";
echo "<PRE>".htmlspecialchars($snoopy->results[2])."</PRE>\n";
