Question

I have searched for this answer, but unable to find it. I am getting the error message, “Parse error: syntax error, unexpected T_VARIABLE” and believe it to be related to the “a” listed on line 30. Any ideas how to make this code right?

<?php
class Crawler {
    protected $markup = ”;
    public function __construct($uri) {
        $this->markup = $this->getMarkup($uri);
    }

    public function getMarkup($uri) {
        return file_get_contents($uri);
    }

    public function get($type) {
        $method = array($this,”_get_”.$type);
        if (method_exists($this,$method[1]))
            return call_user_func($method);
        return false;
    }

    protected function _get_images() {
        if (!empty($this->markup)){
            preg_match_all("/<img([^>]+)\/>/i", $this->markup, $images);
            return !empty($images[1]) ? $images[1] : FALSE;
        }
    }

    protected function _get_links() {
        if (!empty($this->markup)){
            preg_match_all("/<a([^>]+)\>(.*?)\<\/a\>/i", $this->markup, $links);
            return !empty($links[1]) ? $links[1] : FALSE;
        }
    }
}
a 
$crawl = new Crawler("http://www.facebook.com");
$images = $crawl->get("images");
$links = $crawl->get("links");
?>

Remove that a, and use straight quotes " instead of your current curly quotes.
