db2_fetch_array

DB2_FETCH_ARRAY(3)							 1							DB2_FETCH_ARRAY(3)

db2_fetch_array - Returns an array, indexed by column position, representing a row in a result set

SYNOPSIS

       array db2_fetch_array (resource	$stmt, [int  $row_number = -1])

DESCRIPTION

	Returns an array, indexed by column position, representing a row in a result set. The columns are 0-indexed.

PARAMETERS

	      o $stmt
		- A valid stmt resource containing a result set.

	      o $row_number
		-  Requests a specific 1-indexed row from the result set. Passing this parameter results in a PHP warning if the result set uses a
		forward-only cursor.

RETURN VALUES

	Returns a 0-indexed array with column values indexed by the column position representing the next or requested	row  in  the  result  set.
       Returns FALSE if there are no rows left in the result set, or if the row requested by $row_number does not exist in the result set.

EXAMPLES

       Example #1

	      Iterating through a forward-only cursor

	       If you call db2_fetch_array(3) without a specific row number, it automatically retrieves the next row in the result set.

	      <?php

	      $sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
	      $stmt = db2_prepare($conn, $sql);
	      $result = db2_execute($stmt);

	      while ($row = db2_fetch_array($stmt)) {
		  printf ("%-5d %-16s %-32s %10s
",
		      $row[0], $row[1], $row[2], $row[3]);
	      }
	      ?>

	      The above example will output:

	      0     Pook	     cat				    3.20
	      5     Rickety Ride     goat				    9.70
	      2     Smarty	     horse				  350.00

       Example #2

	      Retrieving specific rows with db2_fetch_array(3) from a scrollable cursor

	       If  your  result  set  uses  a scrollable cursor, you can call db2_fetch_array(3) with a specific row number. The following example
	      retrieves every other row in the result set, starting with the second row.

	      <?php

	      $sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
	      $result = db2_exec($stmt, $sql, array('cursor' => DB2_SCROLLABLE));

	      $i=2;
	      while ($row = db2_fetch_array($result, $i)) {
		  printf ("%-5d %-16s %-32s %10s
",
		      $row[0], $row[1], $row[2], $row[3]);
		  $i = $i + 2;
	      }
	      ?>

	      The above example will output:

	      0     Pook	     cat				    3.20
	      5     Rickety Ride     goat				    9.70
	      2     Smarty	     horse				  350.00
