Checking if a link exists?

[merylvingien]

Hi folks, i am trying to automate a link checking system, basicly if a page is accessed, php checks a site to see if a link is present, if so then it displays a link on the page.

Here is the code i have so far:

 

                  if (empty ($row['weblink'])) {$link = "";}
	  else 
	  if (!empty ($row['url'])) {
	  $url1= "{$row['url']}";
	  $homepage = file_get_contents('$url1');
	  $mylink = 'http://www.mysite.com';
	  $pos = strpos($homepage, $mylink); 
	  
	  if ($pos === false) {
                  $link = "";
          } else {
                  $link = "<p>{$row['fname']} has a web site which can be found here <br><a href='http://{$row['weblink']}'>{$row['linktitle']}</a></p><br>";
         }
	 }
	  echo
	  "$link";

 

sommit aint right, as its not echoing the right output when the correct link is present

Any thoughts?

The problem lies within the file_get_contents function. You have no file named $url1, instead use double quotes and your $url1 var will get extrapolated to its value.

You know ive been playing with this for hours, never realised that could be the problem.

 

Many thanks for the solution
