I have had a problem with some scripts I wrote (Screenscrapers) that worked great in PHP4, but stopped working the minute I upgraded to PHP5.
I can change all of my filenames to have the .PHP4 extension and this solves the problem, but since this encompasses a number of sites, internal links and hundreds of files, this is not my first choice solution.
Here is the scraper, what it does, is it takes items from the zazzle Results Page by category, strips out the formatting, adds my affiliate ID and then I can present these items on my page.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Test of scrape</title>
<link rel="stylesheet" type="text/css" href="/css/scraper.css" />
<div class="gridCell " id="page_productsGrid_assetCell1">
$page = file_get_contents("http://www.zazzle.com/cool+smiley+gifts");
//comment out the <span> tags completely
$page = preg_replace('/<span/', "<!-- <span", $page);
$page = preg_replace('/<\/span>/', "<\/span> -->", $page);
$page = preg_replace('/<a /', "<a rel=\"nofollow\" ", $page);
// Regular expression to parse "&rf=" and the $rf_id into the existing link
$test = explode('<div style="position:relative" class="clearfix">',$page);
print "<div class=\"gridCellInfo\" id=\"page_products\">";
This works find in PHP4; not at all in PHP5.
My ideal solution would be an .htaccess file that I could put in any directory under PHP5 to make it default to php4.
I have tried this, to no avail (.htaccess):
AddType text/html .php4
AddHandler php4-script .php .html php5
I have also tried a few alternatives... this appears to be a common problem and I have scoured the web and found no solution.
Here are the two pages in PHP4 and PHP5:
