global vars scope

[naminator]

i have the following code:

<?
//header parser class
require ("parser.php");

global $fp  ;
// open a client connection
function conect($host,$port)
{

  $fp = fsockopen ($host, $port, $errno, $errstr);

  // if a handle is not returned
    if (!$fp)
      {
      return false;
      }
      else
      {
      // get the welcome message
      $welcome = fgets ($fp, 150);
      return true;
      }
}

  function user($user)
  {
  	// send username and read response
	fputs ($fp, "USER $user\n");
	$check = fgets($fp, 50);
	 if (substr($check, 0, 3) == "+OK")
	    {
	    return true;
     	}
     	else {return false;}
	  }


   function pass ($pass){
  	// send password and read response
  	fputs ($fp, "PASS $pass\n");
	  $ack = fgets($fp, 50);
	  if (substr($ack, 0, 3) == "+OK")
	    {
	    return true;
     	}
     	else {return false;}
  }

  function pop3stat()
  {
	 	// send status request and read response
	  	fputs ($fp, "STAT\n");
		  $status = fgets($fp, 50);
		  if (substr($status, 0, 3) == "+OK")
		{
		}
		// error getting status
		else
		{
			die ("Server said: $status");
		}

// get status string
// split by spaces
$arr = explode(" ", $status);
   return $arr;
   }



function getmesg($msgnum, $fp)
{

   if ($msgnum>=$arr[1])
   {
    //////send out the retrieve mesage
    fputs ($fp, "RETR $msgnum\n");
	    //initialize the counter
    $count = 0;

    ///create an array for the counter
	    $MsgArray = array();
    //we need to get this value once before the loop
	    $line = fgets($fp,10000);
      //loop while we find /n  in $line
	      while ( !ereg("^\.\r\n",$line))
	      {
	      //make the array[0]the first line and then [2] and so on...
		     $MsgArray[$count] = $line;
		     // ad one to count
		     $count++;
		     //get the next line and loop
		     $line = fgets($fp,10000);
		        //if the string is empty contains no new line chars then we break out.
		       if(empty($line))	{ break; }
	      }
  }  else  {echo "that message does not exist on the server";}



return $MsgArray;
}
//   while ( list ( $lineNum,$line ) = each ($cool) )
 //   {
  //      echo "$line <BR>\n";
    //}



    function  quit(){
			fputs ($fp, "QUIT\n");
     fclose ($fp);
      }

i use another script to connect to the server using conect(), i then do any of the other functions and it will say that $fp is not a valid stream resource. I think that when i make the connection to the server it declares $fp as the socket connection only within the function, how can i solve this problem

p.s feel freee to use this code

You need to put
global $fp;
Inside of each function that uses $fp.
Kind of a pain but it works.
