SYNOPSIS

       public mixed PDOStatement::fetchObject ([string	$class_name = "stdClass"], [array  $ctor_args])

DESCRIPTION

	Fetches  the  next  row  and  returns  it  as an object. This function is an alternative to PDOStatement.fetch(3) with PDO::FETCH_CLASS or
       PDO::FETCH_OBJ style.

PARAMETERS

	      o $class_name
		- Name of the created class.

	      o $ctor_args
		- Elements of this array are passed to the constructor.

RETURN VALUES

PDOStatement::bindColumn - Bind a column to a PHP variable

SYNOPSIS

       public bool PDOStatement::bindColumn (mixed  $column, mixed  &$param, [int  $type], [int  $maxlen], [mixed  $driverdata])

DESCRIPTION

       PDOStatement.bindColumn(3)  arranges  to  have  a  particular variable bound to a given column in the result-set from a query. Each call to
       PDOStatement.fetch(3) or PDOStatement.fetchAll(3) will update all the variables that are bound to columns.

       Note

	       Since information about the columns is not always available to PDO until the statement is executed,  portable  applications  should
	      call this function afterPDOStatement.execute(3).

	       However, to be able to bind a LOB column as a stream when using the PgSQL driver, applications should call this method before call-
	      ing PDOStatement.execute(3), otherwise the large object OID will be returned as an integer.

PARAMETERS

	      o $column
		- Number of the column (1-indexed) or name of the column in the result set. If using the column  name,	be  aware  that  the  name
		should match the case of the column, as returned by the driver.

	      o $param
		- Name of the PHP variable to which the column will be bound.

	      o $type
		- Data type of the parameter, specified by the PDO::PARAM_* constants.

	      o $maxlen
		- A hint for pre-allocation.

	      o $driverdata
		- Optional parameter(s) for the driver.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	      Binding result set output to PHP variables

	       Binding columns in the result set to PHP variables is an effective way to make the data contained in each row immediately available
	      to your application. The following example demonstrates how PDO allows you to bind and retrieve columns with a  variety  of  options
	      and with intelligent defaults.

	      <?php
	      function readData($dbh) {
		$sql = 'SELECT name, colour, calories FROM fruit';
		try {
		  $stmt = $dbh->prepare($sql);
		  $stmt->execute();

		  /* Bind by column number */
		  $stmt->bindColumn(1, $name);
		  $stmt->bindColumn(2, $colour);

		  /* Bind by column name */
		  $stmt->bindColumn('calories', $cals);

		  while ($row = $stmt->fetch(PDO::FETCH_BOUND)) {
		    $data = $name . "	" . $colour . "	" . $cals . "
";
		    print $data;
		  }
		}
		catch (PDOException $e) {
		  print $e->getMessage();
		}
	      }
	      readData($dbh);
	      ?>

	      The above example will output:

	      apple   red     150
	      banana  yellow  175
	      kiwi    green   75
	      orange  orange  150
	      mango   red     200
	      strawberry      red     25
