Screen scraper
Hey. I am trying to implement a screen capture script on my website and still have the following set. What I'm ultimately trying to do is replace all references in the $ results variable with "ResultsDetails.aspx?" to "results-scrape-details /", then output again. Can anyone point me in the right direction?
<?php
$url = "http://mysite:90/Testing/label/stuff/ResultsIndex.aspx";
$raw = file_get_contents($url);
$newlines = array("\t","\n","\r","\x20\x20","\0","\x0B");
$content = str_replace($newlines, "", html_entity_decode($raw));
$start = strpos($content,"<div id='pageBack'");
$end = strpos($content,'</body>',$start) + 6;
$results = substr($content,$start,$end-$start);
$pattern = 'ResultsDetails.aspx?';
$replacement = 'results-scrape-details/';
preg_replace($pattern, $replacement, $results);
echo $results;

Use a DOM tool like PHP Simple HTML DOM . With it, you can find all the links you are looking for with Jqueryish syntax.
// Create DOM object from HTML source
$dom = file_get_html('http://www.domain.com/path/to/page');
// Iterate all matching links
foreach ($dom->find('a[href^=ResultsDetails.aspx') as $node) {
// Replace href attribute value
$node->href = 'results-scrape-detail/';
}
// Output modified DOM
echo $dom->outertext;
