       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:

		     o PDOStatement::getColumnMeta [name]

       string mysql_field_name (resource  $result, int	$field_offset)

DESCRIPTION

       mysql_field_name(3) returns the name of the specified field index.

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

	      o $
		field_offset -The numerical field offset. The $field_offset starts at 0. If $field_offset  does  not  exist,  an  error  of  level
		E_WARNING is also issued.

	The name of the specified field index on success or FALSE on failure.

       Example #1

	      mysql_field_name(3) example

	      <?php
	      /* The users table consists of three fields:
	       *   user_id
	       *   username
	       *   password.
	       */
	      $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
	      if (!$link) {
		  die('Could not connect to MySQL server: ' . mysql_error());
	      }
	      $dbname = 'mydb';
	      $db_selected = mysql_select_db($dbname, $link);
	      if (!$db_selected) {
		  die("Could not set $dbname: " . mysql_error());
	      }
	      $res = mysql_query('select * from users', $link);

	      echo mysql_field_name($res, 0) . "
";
	      echo mysql_field_name($res, 2);
	      ?>

	      The above example will output:

	      user_id
	      password

mysql_list_fields - List MySQL table fields

SYNOPSIS

       Warning

	      This  function  was deprecated in PHP 5.4.0, and will be removed in the future, along with the entirety of the original MySQL exten-
	      sion. 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:

		     oSQL Query:
		       SHOW COLUMNS FROM sometable

       resource mysql_list_fields (string  $database_name, string  $table_name, [resource  $link_identifier = NULL])

DESCRIPTION

	Retrieves information about the given table name.

	This  function	is  deprecated.  It  is  preferable  to use mysql_query(3) to issue an SQL SHOW COLUMNS FROM table [LIKE 'name'] statement
       instead.

	      o $database_name
		- The name of the database that's being queried.

	      o $table_name
		- The name of the table that's being queried.

	      o $
		link_identifier -The MySQL connection. If the link identifier is not specified,  the  last  link  opened  by  mysql_connect(3)	is
		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	A result pointer resource on success, or FALSE on failure.

	The returned result can be used with mysql_field_flags(3), mysql_field_len(3), mysql_field_name(3) and mysql_field_type(3).

       Example #1

	      Alternate to deprecated mysql_list_fields(3)

	      <?php
	      $result = mysql_query("SHOW COLUMNS FROM sometable");
	      if (!$result) {
		  echo 'Could not run query: ' . mysql_error();
		  exit;
	      }
	      if (mysql_num_rows($result) > 0) {
		  while ($row = mysql_fetch_assoc($result)) {
		      print_r($row);
		  }
	      }
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [Field] => id
		  [Type] => int(7)
		  [Null] =>
		  [Key] => PRI
		  [Default] =>
		  [Extra] => auto_increment
	      )
	      Array
	      (
		  [Field] => email
		  [Type] => varchar(100)
		  [Null] =>
		  [Key] =>
		  [Default] =>
		  [Extra] =>
	      )

       Note

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

       mysql_field_flags(3), mysql_info(3).
