Question

I was trying to return a set of objects.

But this code gives me the following error:

Catchable fatal error: Object of class User could not be converted to string in …

 public function fetchObject($psClassname ='',$paParams =array()){             $lrResource = $this->mrQueryResource;             $liResult = null;              while($row = mysql_fetch_object($lrResource,$psClassname,$paParams)){                 $liResult .= $row;     <-this line produces the error             }             return $liResult;          } 

Answer 1

In your code $row is a an object (you’ve used mysql_fetch_object), and the .= operator tries to build a string, concatenating $liResult and $row. I believe this behaviour only works if your object implements a toString method

You could return an array of rows using this code:

public function fetchObject($psClassname ="",$paParams =array()){         $lrResource = $this->mrQueryResource;         $liResult = array();         while($row = mysql_fetch_object($lrResource,$psClassname,$paParams)){                 $liResult[] = $row;         }         return $liResult; }
