PHP unlink function


This is the code




$query = mysql_query("SELECT avatar FROM users WHERE UserID = ".$userID."");
$row = mysql_fetch_array($query);
$user_avatar = trim($row['avatar']);
unlink($user_avatar);



but for some reason i get this error Warning:unlink();



why $user_avatar returns empty ? and if i echo it shows t_cabbbccebbfhdb.jpg

  1. unlink remove files whereas unset is for variables.

    If the variable returns empty, perhaps the query does not return any records. Did you try to run the query manually?

    $user_avatar = trim($row['avatar']);
    unset($user_avatar);

    //if you want to unlink file then

    if(!empty($user_avatar)) {
    unlink($home.$user_avatar); // $yourFile should have full path to your file
    }
