How to replace URL with anchor tag contain dynamic text using PHP?

how do i parse or convert the link to proper <a> link format with PHP?

"http://developer.postmarkapp.com/developer-inbound-webhook.html"

Here what postmark JSON API StrippedTextReply response:

"This is example body with link <http://developer.postmarkapp.com/developer-process-parse.html>"

Possible format:
This is example body with (any link) <http://>
This is example body with <http://> (any link)

Expecting result:

'This is example body with <a href="http://developer.postmarkapp.com/developer-process-parse.html">link</a>'

Note that text of anchor in dynamic that is before URL in string.

Use regex in preg_replace() to replace URL with anchor. The regex select URL and replace it with anchor tag contain that URL in href attribute.

preg_replace("/([\w]+)[\s]+<([^>]+)>/", "<a href='$2'>$1</a>", $str);

Edit: If position of text of anchor in string is unknown (before or after of URL), you need to use preg_replace_callback() to check value of matched group.

preg_replace_callback("/([\w]+)[\s]+<([^>]+)>([\w\s]+)?/", function($matches){
if (isset($matches[3]))
    return "{$matches[1]} <a href='{$matches[2]}'>{$matches[3]}</a>";
else 
    return "<a href='{$matches[2]}'>{$matches[1]}</a>"; 
}, $str);
