regex help with getting tag content in PHP

Question

so I have the code

function getTagContent($string, $tagname) {

    $pattern = \"/<$tagname.*?>(.*)<\\/$tagname>/\";
    preg_match($pattern, $string         


        

Answer 1

Have your php function getTagContent like this:

function getTagContent($string, $tagname) {
    $pattern = '/<'.$tagname.'[^>]*>(.*?)<\/'.$tagname.'>/is';
    preg_match($pattern, $string, $matches);
    print_r($matches);
}

It is important to use non-greedy match all .*? for matching text between start and end of tag and equally important is to use flags s for DOTALL (matches new line as well) and i for ignore case comparison.
