Let's say your target page, is this pretty decent sized document at
W3.org: http://validator.w3.org/docs/users.html
View the page source manually to find some unique portions that
delineate the important section, and plug them into the $cStartStr and
$cEndStr variables. For this exercise I chose to extract the section
labeled "Interpreting the results".
<?php
$cTargetPage = "http://validator.w3.org/docs/users.html";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $cTargetPage);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$cPgStr = curl_exec($ch);
curl_close($ch);
$cStartStr = "<div id=\"Interpret\" class=\"stb\">";
$cEndStr = "</div>";
$cPageTail = stristr($cPgStr, $cStartStr);
$nUsefulDataEndPos = strpos($cPageTail, $cEndStr);
$cUsefulData = substr($cPageTail, 0, $nUsefulDataEndPos+6);
echo($cUsefulData);
?>
Run the script and save the relevent portion somewhere useful instead
of echoing it out. :-)
