Looping Through Post Content w/stripos

    Hello,

    I have a plugin that gets the first image from the content of a post. Here’s the code:

    // Image extraction
        $image = '';
        $x = stripos($content, '<img');

        if ($x !== false) {
            $x = stripos($content, 'src="', $x);
            if ($x !== false) {
                $x += 5;
                $y = strpos($content, '"', $x);
                $image = substr($content, $x, $y-$x);
            }
        }

    The “$x = stripos($content, ‘<img’);” finds the first instance of <img and returns the result. I would like to modify this to get the 2nd image if the first image found is “header.gif”.

    Any suggestions on how to modify the code to accomplish this?

            $x = stripos($content, 'src="', $x);
            if ($x !== false) {
                $x += 5;
                $y = strpos($content, '"', $x);
                $image = substr($content, $x, $y-$x);
            }
        }
// compare the result with 'header.gif' - you need the full path, i.e. what your first image extraction results;
if($image == 'header.gif') :
// shorten $content into $content2, incase you need $content later
$content2 = substr($content, $y);
// Image extraction second time:
        $image = '';
        $x = stripos($content2, '<img');

        if ($x !== false) {
            $x = stripos($content2, 'src="', $x);
            if ($x !== false) {
                $x += 5;
                $y = strpos($content2, '"', $x);
                $image = substr($content2, $x, $y-$x);
            }
        }
endif;

    untested ??
