dynamic class methods

[nileshd]

I have the following piece of code with which i am trying to populate a class from a resultSet. I find the common fieldNames in the resultSet and Class and dynamically build the set method for the class and try to set these values, but it dont seem to be working. Does anyone know if I can can call $thisClass->$setMethod, where $setMethod is built on the fly. below is my code. Any help would be greatly appreciated.

 // Function to populate Class from ResultSet
 function populateInfoObjectFromResultSet($resultSet,&$infoObject)
 {
          global $db;

      // Getting all fieldNames
          $fieldNames = array_keys ($resultSet->fields);



         for ($a=0; $a<count($fieldNames); $a++)
         {

                   $methodName = "set".ucfirst($fieldNames[$a]);


                   // if method exists, set it in the Info Object                       
                   if (method_exists($infoObject,$methodName))
                   {	     
                         $methodAppend = $methodName."(\"".$resultSet->fields[$fieldNames[$a]]."\")";
                        echo "Method $methodAppend Exists.<br>";

                         // trying to execute method on class
                         $infoObject->$methodAppend;


                   }

         }

         return $infoObject;

 }

Thanks,

This shortened example does what I think you are attempting. The way you are calling the method wasn't quite right:

<?php 

class textObj {
  var $Objvar;

  function setObjvar ($v) {
    $this->Objvar = $v;
    echo "Objvar = " . $this->Objvar . "<p>";
  }
}

function populate ($v, &$f) {
  $meth = "set"  . 'Objvar';
  $f->$meth($v);
}

$ob = new textObj();
$ob->setObjvar(1);
populate (2, $ob);
?>

It worked good for me.. I thought I'd post the finished code in case anybody needs a method like this, to populate a class from an ADODB resultset.

 /**
  * @return the class that was input with populated information from the resultset
  * @param resultSet ADODB ResultSet
  * @param infoObject Regular Class
  * @desc This function takes an ADODB resultset and a class and attempts to populate the class. PRECONDITIONS : the fieldName in the table need to be the same as the class variables. and setFieldname methods defined for each member variable in the class. If fields from the result set matches the fieldname in the class, the class variable is populated with the value from the resultset data.

 function populateInfoObjectFromResultSet($resultSet,$infoObject)
 {
         global $db;

         $methodPrefix = "set";

         // getting all the fieldNames from the ResultSet 
  $fieldNames = array_keys ($resultSet->fields);

         for ($a=0; $a<count($fieldNames); $a++)
         {
                   // Building Method Name
                   $methodName = $methodPrefix.ucfirst($fieldNames[$a]);

                   // If method exist in infoObject, then populate object
                   if (method_exists($infoObject,$methodName))
                   {
                            $infoObject->$methodName($resultSet->fields[$fieldNames[$a]]);
                   }

         }

  return $infoObject;
 }
