Preg Replace / Preg Match for href in html link?

Question

Anybody have a regular expression to replace the following code:

<a href="originalLink">hi</a>

with:

<a href="newLink">hi</a>

Answer 1

PHP Simple HTML Dom Parser example:

// Create DOM from URL or file
$html = file_get_html('http://www.google.com/');

// Find all links 
$anchors = $html->find('a');

$count = count($anchors);

for($i=0;$i<$count;$i++) {
    $anchors[$i]->href = 'someLink.html';
}

If you know the href of the anchor you want to replace, do something like:

$html->find('a[href=something]', 0)->href = 'someLink.php';
