	      be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

		     omysqli_fetch_lengths(3)

		     o PDOStatement::getColumnMeta

       array mysql_fetch_lengths (resource  $result)

DESCRIPTION
	Returns an array that corresponds to the lengths of each field in the last row fetched by MySQL.

       mysql_fetch_lengths(3) stores the lengths of each result column in the  last  row  returned  by	mysql_fetch_row(3),  mysql_fetch_assoc(3),
       mysql_fetch_array(3), and mysql_fetch_object(3) in an array, starting at offset 0.

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

	An array of lengths on success or FALSE on failure.

       Example #1

	      A mysql_fetch_lengths(3) example

	      <?php
	      $result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
	      if (!$result) {
		  echo 'Could not run query: ' . mysql_error();
		  exit;
	      }
	      $row     = mysql_fetch_assoc($result);
	      $lengths = mysql_fetch_lengths($result);

	      print_r($row);
	      print_r($lengths);
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [id] => 42
		  [email] => user@example.com
	      )
	      Array
	      (
		  [0] => 2
		  [1] => 16
	      )

       mysql_field_len(3), mysql_fetch_row(3), strlen(3).
