php regex to get string inside href tag

Question

I need a regex that will give me the string inside an href tag and inside the quotes also.

For example i need to extract theurltoget.com in the following:

Answer 1

For all href values replacement:

function replaceHref($html, $replaceStr)
{
    $match = array();
    $url   = preg_match_all('/<a [^>]*href="(.+)"/', $html, $match);

    if(count($match))
    {
        for($j=0; $j<count($match); $j++)
        {
            $html = str_replace($match[1][$j], $replaceStr.urlencode($match[1][$j]), $html);
        }
    }
    return $html;
}
$replaceStr  = "http://affilate.domain.com?cam=1&url=";
$replaceHtml = replaceHref($html, $replaceStr);

echo $replaceHtml;

Answer 2

Because Positive and Negative Lookbehind are cool

/(?<=href=\").+(?=\")/

It will match only what you want, without quotation marks

Array ( [0] => theurltoget.com )

Let's start with the simplest case - a well formatted link with no extra attributes:

/<a href=\"([^\"]*)\">(.*)<\/a>/iU

Answer 4

Use the answer by @Alec if you're only looking for the base url part (the 2nd part of the question by @David)!

$html = '<a href="http://www.mydomain.com/page.html" class="myclass" rel="myrel">URL</a>';
$url = preg_match('/<a href="(.+)">/', $html, $match);
$info = parse_url($match[1]);

This will give you:

$info
Array
(
    [scheme] => http
    [host] => www.mydomain.com
    [path] => /page.html" class="myclass" rel="myrel
)

So you can use $href = $info["scheme"] . "://" . $info["host"] Which gives you:

// http://www.mydomain.com

When you are looking for the entire url between the href, You should be using another regex, for instance the regex provided by @user2520237.

$html = '<a href="http://www.mydomain.com/page.html" class="myclass" rel="myrel">URL</a>';
$url = preg_match('/href=["\']?([^"\'>]+)["\']?/', $html, $match);
$info = parse_url($match[1]);

this will give you:

$info
Array
(
    [scheme] => http
    [host] => www.mydomain.com
    [path] => /page.html
)

Now you can use $href = $info["scheme"] . "://" . $info["host"] . $info["path"]; Which gives you:

// http://www.mydomain.com/page.html

Answer 5

/href="(https?://[^/]*)/

I think you should be able to handle the rest.

Answer 6

$html = '<a href="http://www.mydomain.com/page.html">URL</a>';

$url = preg_match('/<a href="(.+)">/', $html, $match);

$info = parse_url($match[1]);

echo $info['scheme'].'://'.$info['host']; // http://www.mydomain.com
