Re: Warning: Supplied argument is not a valid PostgreSQL link resource

I tried to change what lbayuk pointed out.

Now my functions look like this, but I still get the same warning message

<?
     global $conn;

     function open_conn(){

 $conn_string = "host=angua.skjoldhoej.dk port=5432 dbname=fcs user=fcs
password=janfcs";
 $conn = pg_connect($conn_string) or die(pg_last_error());

   if (!$conn) {
      echo "Kunne ikke oprette en forbindelse til PostGre databasen.";
      return;
   }
     }

     function close_conn(){
 if(!pg_close($conn)) {
    echo "Kunne ikke lukke forbindelsen til PostGre!";
    return;
   }
     }

     function sql_execute($query)
     {
 $resultat = pg_exec($conn, $query);

          if(!$resultat) {
      echo "Kunne ikke udf�re: <em>$query</em>";
      return;
   }
     }

     function sql_execute_receive($query)
     {
  $resultat = pg_exec($conn, $query);
  $resultat_array = array();

 if(!$resultat)
 {
    echo "Kunne ikke udf�re: <em>$query</em>";
    return;
 }

 if (pg_numrows($resultat)>0)
 {
   $row = 0;
   while ($item = pg_fetch_array($resultat, $row, PGSQL_ASSOC))
   {
        $resultat_array[] = $item;
        $row++;
   }
 }
          return $resultat_array;
      }
?>
