sorry guys i am learning php, sometimes i see on tutorials people use -> i been wondering what does this means in php ?

for example like this i saw on many tutorials

if($resultSet->num_rows != 0) {
    // code here ...
}

see simple code above has $resultSet->num_rows what does this means -> and what is another way to make this code right so i can understand this ?

i am learning php and wanted to ask only what does this means and if there's any other ways instead of using ->

it points to a parameter/method of an object or class. So $resultSet here is an object or instance of a class, and `num_rows` is a property of that object. – Jeff May 29 '17 at 15:32
@Jeff i don't get it jeff. because we can use this for example `mysqli_query("");` but some people use it like this `mysqli->query("");` – wesley --------------------- May 29 '17 at 15:35
@YvesLeBorg if i am not wrong, it means `=` "equal" and in same time it means `_` "underscore" ? – wesley --------------------- May 29 '17 at 15:36
these are 2 different ways of using the `mysqli_` extension. RTFM and it will explain [TFM page in question](http://php.net/manual/en/mysqli.quickstart.dual-interface.php) – RiggsFolly May 29 '17 at 15:37
Just lookup how to handle objects in PHP and you will find the answer. – RST May 29 '17 at 15:43
