This worked till I added some code, Now it does not,

[guymclarenza]

<?php
include("classes/DomDocumentParser.php");

//this could be the problem it appears in the error file
$alreadyCrawled() = array();
$crawling = array();

$startUrl = "https://imagimedia.co.za"; //Get variable from input

	$hnam = str_replace("http://", "", "$startUrl");
	$hnam = str_replace("https://", "", "$hnam");
	$hnam = str_replace("www.", "", "$hnam");	
	$hnam = substr($hnam, 0, -6);
		
function createLink($src, $url) {
	$scheme = parse_url($url)["scheme"];
	$host = parse_url($url)["host"];

	
 if(substr($src, 0, 2) == "//") {
 	$src = $scheme.":".$src;
	}
  else if(substr($src, 0, 1) == "/") {
 	$src = $scheme."://".$host.$src;
	}
	else if(substr($src, 0, 2) == "./") {
 	$src = $scheme."://".$host.dirname(parse_url($url)["path"]).substr($src, 1);
	}
	else if(substr($src, 0, 3) == "../") {
 	$src = $scheme."://".$host."/".substr($src, 3);
	}
	else if (substr($src, 0, 4) != "http") {
	$src = $scheme."://".$host."/".$src;
	}
	return $src;
	 }


function followLinks($url) {
	
	global $hnam;
	global $alreadyCrawled;
	global $crawling;
	
	$parser = new DomDocumentParser($url);
	
	$linkList = $parser->getLinks();
	
	foreach($linkList as $link) {
		$href = $link->getAttribute("href");
		
		if(strpos($href, "#") !== false) {
		continue;
		}
		else if(substr($href, 0, 11) == "javascript:") {
		continue;
		}
		
		$href = createLink($href, $url);
		
		if(strpos($href, "$hnam") ==  false) {
			continue;
			}		
		
		//this could be the problem
		if(!in_array($href, $alreadyCrawled)) {
			$alreadyCrawled[] = $href;
			$crawling[] = $href;
			
			
			
			//insert $href
		
		}
		
			
		echo $href."<br />";
	}
 	array_shift($crawling);
 	
 	foreach($crawling as $site) {
 		followLinks($site);
 	}
}

followLinks($startUrl);
?>

include file

<?php
class DomDocumentParser {

	private $doc;
	
	public function __construct($url) {
		
		$options = array(
			'http'=>array('method'=>"GET", 'header'=>"User-Agent: imagimediaBot/0.1\n")
			);
		$context = stream_context_create($options);
		
		$this->doc = new DomDocument();
		@$this->doc->loadHTML(file_get_contents($url, false, $context));	
	}
	
	public function getLinks() {
		return $this->doc->getElementsByTagName("a");
	}

}
?>

added include file

//this could be the problem it appears in the error file
$alreadyCrawled() = array();
$crawling = array();

It is. Look at the second assignment that did not produce an error. See the difference?

However, telling us it does not work is of no use. What new code did you add? What doesn't work? Do you get an error or do you get a different output than you expect? If so what is that?

The error codes are on the bottom of the image. 

Oh FFS now that you mention it, what a twat I am() 

Thanks for pointing out the wood I couldn't see for the trees
