mysql_free_result - Free result memory

SYNOPSIS
       Warning

	      This  extension  is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
	      be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

		     omysqli_free_result(3)

		     oAssign the value of
		       NULL to the PDO object, or PDOStatement::closeCursor

       bool mysql_free_result (resource  $result)

DESCRIPTION
       mysql_free_result(3) will free all memory associated with the result identifier $result.

       mysql_free_result(3) only needs to be called if you are concerned about how much memory is being used for queries that return large  result
       sets. All associated result memory is automatically freed at the end of the script's execution.

	      o $
		result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).

	Returns TRUE on success or FALSE on failure.

	If a non-resource is used for the $result, an error of level E_WARNING will be emitted. It's worth noting that mysql_query(3) only returns
       a resource for SELECT, SHOW, EXPLAIN, and DESCRIBE queries.

       Example #1

	      A mysql_free_result(3) example

	      <?php
	      $result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
	      if (!$result) {
		  echo 'Could not run query: ' . mysql_error();
		  exit;
	      }
	      /* Use the result, assuming we're done with it afterwards */
	      $row = mysql_fetch_assoc($result);

	      /* Now we free up the result and continue on with our script */
	      mysql_free_result($result);

	      echo $row['id'];
	      echo $row['email'];
	      ?>

       Note

	       For backward compatibility, the following deprecated alias may be used: mysql_freeresult(3)

       mysql_query(3), is_resource(3).
