I'm using this code to prepend the URL variable inside the src tag for images. Now I want an regex code that makes it possible to search for <link>
tags and add the URL variable inside the link tags href attribute. This is the code I have for the images; might help explain things:
function imgprepend_proxy($matches2) {
$url = (substr($_GET['url'], 0, 7) == 'http://') ? $_GET['url'] : "http://{$_GET['url']}";
$prepend2 = $matches2[2] ? $matches2[2] : $url;
$prepend2 = $prepend2 . '/';
return $matches2[1] . $prepend2 . $matches2[3];
}
$new_content = preg_replace_callback(
'|(href=[\'"]?)(https?://)?([^\'"\s]+[\'"]?)|i',
'prepend_proxy',
preg_replace_callback(
'|(src=[\'"]?)(https?://)?([^\'"\s]+[\'"]?)|i',
'imgprepend_proxy',
$content
)
);
