$link = "<a href='test.php'>test</a>";
preg_match('~<a .*?href=[\'"]+(.*?)[\'"]+.*?>(.*?)</a>~ims', $link, $result);
//result[1] == test.php
//result[2] == test

or better one, if you want "test"

$link = "<a href='test.php'>test</a>";
$result = strip_tags($link);

eventually, you can look at DOMDocument

<?php
$link="<a href='test.php'>test</a>";
libxml_use_internal_errors(true);
$dom = new domdocument;
$dom->loadHTML($link);
foreach ($dom->getElementsByTagName("a") as $a) {
    echo $a->textContent, "\n";
    echo $a->getAttribute("href"), "\n";
}

You're not specifically concrete about the string you'd like to parse, but a very easy way to do this with PHP is to parse it as a formatted string in your case (Demo):

$link = "<a href='test.php'>test</a>";

$result = sscanf($link, "<a href='%[^']'>%[^<]</a>", $href, $text);

var_dump($result, $href, $text);

However this is not very stable if the format of the link changes, so you should better look for DomDocument which has been already answered.
