Solution

PHP code

  $sql="select * from newes where advertisingid =1";$abc =mysql_query($sql);/**while($num =mysql_fetch_array($abc)){    $num}*/

Q: How can I return an object class?
For example, Newes $ newes = new Newes ();
$ Newes = mysql_query ($ SQL); // Is this an object class returned?
Super beginner confused... please help me explain. thank you.

------ Solution --------------------
What is the relationship between the two codes ??
First returns the object class
The second mysql_query returns the result set of the resource type.
------ Solution --------------------
Such as: private int advertisingid; changed to private $ advertisingid;

Your set is the definition method in java.
------ Solution --------------------
Mysql_fetch_row ()
Mysql_fetch_array ()
Mysql_fetch_assoc ()
