How to check if a url exists inside a webpage

[firestarter30]

Hello ,

Im trying to make a very simple link trade script , which checks in a page exists and after searches to that page to find a link (in this case my link).

But i got stuck in the lalst step of finding my link on a given page.

Hope you can help me with that

 

<?php require_once('Connections/my_conn.php'); ?>
<?php 
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$myurl= 'http://mywebsite.com';
//check if the remote site url exists
function url_exists($url) {
$ch = @curl_init($url);
@curl_setopt($ch, CURLOPT_HEADER, TRUE);
@curl_setopt($ch, CURLOPT_NOBODY, TRUE);
@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
@curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$status = array();
preg_match('/HTTP\/.* ([0-9]+) .*/', @curl_exec($ch) , $status);
}
//check if my link exists in the remote site


if(($status[1] == 200) && ($myurl==             )); {

//Insert into database code here

}
?>

 

I would like a  little help on how to check if my link exist in the trader's url.

 

Thanks in advance
