mysql_fetch_lengths - Get the length of each output in a result

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_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_result - Get result data

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_data_seek(3) in conjunction with mysqli_field_seek(3) and mysqli_fetch_field(3)

		     o PDOStatement::fetchColumn

       string mysql_result (resource  $result, int  $row, [mixed  $field])

DESCRIPTION

	Retrieves the contents of one cell from a MySQL result set.

	When working on large result sets, you should consider using one of the functions that fetch an entire row  (specified	below).  As  these
       functions return the contents of multiple cells in one function call, they're MUCH quicker than mysql_result(3). Also, note that specifying
       a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.

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

	      o $row
		- The row number from the result that's being retrieved. Row numbers start at 0.

	      o $field
		- The name or offset of the field being retrieved.  It can be the field's offset, the field's name, or the field's table dot field
		name (tablename.fieldname). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column
		name. If undefined, the first field is retrieved.

	The contents of one cell from a MySQL result set on success, or FALSE on failure.

       Example #1

	      mysql_result(3) example

	      <?php
	      $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
	      if (!$link) {
		  die('Could not connect: ' . mysql_error());
	      }
	      if (!mysql_select_db('database_name')) {
		  die('Could not select database: ' . mysql_error());
	      }
	      $result = mysql_query('SELECT name FROM work.employee');
	      if (!$result) {
		  die('Could not query:' . mysql_error());
	      }
	      echo mysql_result($result, 2); // outputs third employee's name

	      mysql_close($link);
	      ?>

       Note

	       Calls to mysql_result(3) should not be mixed with calls to other functions that deal with the result set.

       mysql_fetch_row(3), mysql_fetch_array(3), mysql_fetch_assoc(3), mysql_fetch_object(3).
