How to replace specific tag with regex in php?

Suppose I have two links in my content. How can I find the specific links containing the $string and replace with words only. 

$string = 'dog';
$content = 'a quick brown <a href="some-link"> fox</a> jumps over a lazy <a href="another-link"> dog</a>';
$new_content =  preg_replace('<a.+href="(.*)".*> '.$string.'</a>', $string, $content);

I have tried with '~<a.+href="(.*)".*> '.$string.'</a>~' but its removing all the content between those anchors too.

Whats wrong ?

update:

replace <a href="another-link"> dog</a> with dog only and leave <a href="some-link"> fox</a> as it is.

Just use lazy quantifier, ie ?, and add delimiter to the regex:

$string = 'dog';
$content = 'a quick brown <a href="some-link"> fox</a> jumps over a lazy <a href="another-link"> dog</a>';
$new_content =  preg_replace('~<a.+?href="(.*?)".*> '.$string.'</a>~', $string, $content);
//                         here ___^  and  __^

You could also reduce to:

$new_content =  preg_replace("~<a[^>]+>\s*$string\s*</a>~", $string, $content);

Try this to replace the anchor text to given string with preg_replace,

$string = 'dog';
$content = 'a quick brown <a href="some-link"> fox</a> jumps over a lazy <a href="another-link"> dog</a>';

echo preg_replace('/<a(.+?)>.+?<\/a>/i',"<a$1>".$string."</a>",$content);
