		  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);

MYSQL_FIELD_TYPE(3)							 1						       MYSQL_FIELD_TYPE(3)

mysql_field_type - Get the type of the specified field 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_field_direct(3) [type]

		     o PDOStatement::getColumnMeta [driver:decl_type] or [pdo_type]

       string mysql_field_type (resource  $result, int	$field_offset)

DESCRIPTION

       mysql_field_type(3) is similar to the mysql_field_name(3) function. The arguments are identical, but the field type is returned instead.

	      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 returned field type will be one of "int", "real", "string", "blob", and others as detailed in the MySQL documentation.

       Example #1

	      mysql_field_type(3) example

	      <?php
	      mysql_connect("localhost", "mysql_username", "mysql_password");
	      mysql_select_db("mysql");
	      $result = mysql_query("SELECT * FROM func");
	      $fields = mysql_num_fields($result);
	      $rows   = mysql_num_rows($result);
	      $table  = mysql_field_table($result, 0);
	      echo "Your '" . $table . "' table has " . $fields . " fields and " . $rows . " record(s)
";
	      echo "The table has the following fields:
";
	      for ($i=0; $i < $fields; $i++) {
		  $type  = mysql_field_type($result, $i);
		  $name  = mysql_field_name($result, $i);
		  $len	 = mysql_field_len($result, $i);
		  $flags = mysql_field_flags($result, $i);
		  echo $type . " " . $name . " " . $len . " " . $flags . "
";
	      }
	      mysql_free_result($result);
	      mysql_close();
	      ?>

	      The above example will output something similar to:

	      Your 'func' table has 4 fields and 1 record(s)
	      The table has the following fields:
	      string name 64 not_null primary_key binary
	      int ret 1 not_null
	      string dl 128 not_null
	      string type 9 not_null enum

       Note

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

       mysql_field_name(3), mysql_field_len(3).
