Re[2]: [PHP4BETA] count($array,1) or count($array)

The tip is wrong. 

<?

function uniqueArray($array)  
{ 
  // Get unique elts as keys in assoc. array 
  for ($i=0,$n=count($array, 1);$i<$n;$i++) 
      $u_array[$array[$i]] = 1; 

  // Copy keys only into another array 
  reset($u_array, 1); 
  for ($i=0,$n=count($u_array, 1);$i<$n;$i++) { 
      $unduplicated_array[] = key($u_array, 1); 
      next($u_array, 1); 
  } 
  return $unduplicated_array; 
} 

$x = array( 1 , 1 , 3 , 4 , 4 , 5 ) ; 

echo uniqueArray( $x ) ; 

?>

results in 

Warning: Wrong parameter count for count() in test2.php4 on line 6
Warning: Wrong parameter count for reset() in test2.php4 on line 10
Warning: Wrong parameter count for count() in test2.php4 on line 11

This works as expected: 

function uniqueArray($array)  
{ 
  // Get unique elts as keys in assoc. array 
  for ($i=0,$n=count($array);$i<$n;$i++) 
      $u_array[$array[$i]] = 1; 

  // Copy keys only into another array 
  reset($u_array); 
  for ($i=0,$n=count($u_array);$i<$n;$i++) { 
      $unduplicated_array[] = key($u_array); 
      next($u_array); 
  } 
  return $unduplicated_array; 
}
