"find all hrefs in page and replace with link maintaining previous link - php" Answer’s


Use PHP's DomDocument to parse the page

$doc = new DOMDocument();

// load the string into the DOM (this is your page's HTML), see below for more info
$doc->loadHTML('<a href="http://www.google.com">Google</a>');

//Loop through each <a> tag in the dom and change the href property
foreach($doc->getElementsByTagName('a') as $anchor) {
    $link = $anchor->getAttribute('href');
    $link = 'http://www.example.com/?loadpage='.urlencode($link);
    $anchor->setAttribute('href', $link);
echo $doc->saveHTML();

If you don't have the HTML as a string, you may use cUrl (docs) to grab the HTML, or you can use the loadHTMLFile method of DomDocument
