How do you get particular href attribute from a string?

Answer 1

There are various ways to do it. One technique would be to look for occurrences of "href", and then get the next part of the string that's surrounded by double quotes (as a valid anchor tag will always have those). Here's a quick example:

// returns a list of urls of any anchor tags in the input string

function findUrls($input){

$part = stristr($input, "href");

$urls = array();

while($part != ''){

$parts = explode('"', $part, 3);

if(count($parts == 3)) $urls[] = $parts[1];

$part = stristr($parts[2], 'href');

}

return $urls;

}
