使用php检索<a href>标记的多个值

Question

I need to extract the link value which is stored in a <a> tag by using php code.

I used below code

$url = '<a title="Question" href="http://stackoverflow.com/questions/ask">t</a>';
preg_match("/href=\"(.*?)\"/i", $url, $matches);
print_r($matches);

With the above code I can able to get the value of a single href. But it is not working for multiple href in a string(i.e $url = '<a title="Question" href="http://stackoverflow.com/questions/ask">t</a><a href="x.php">x</a>';). How can I achieve this?

Answer 1

Use preg_match_all() to get all the matches, not just the first.

$url = '<a title="Question" href="http://stackoverflow.com/questions/ask">t</a>&nbsp;<a href="x.php">x</a>';
preg_match_all("/href=\"(.*?)\"/i", $url, $matches);
print_r($matches);
