mysql_field_name -- Get the name of the specified field in a result
Description
string mysql_field_name (resource result, int field_index)
mysql_field_name() returns the name of the specified field index.
result must be a valid result identifier and field_index is the numerical
offset of the field.

e.g. The index of the third field would actually be 2, the index of the fourth field would
be 3 and so on.

Example 1. mysql_field_name() example
// The users table consists of three fields:
// user_id
// username
// password.
$link = mysql_connect('localhost', $user, "secret");
mysql_select_db($dbname, $link)
or die("Could not set $dbname");
$res = mysql_query("select * from users", $link);
echo mysql_field_name($res, 0) . "\n";
echo mysql_field_name($res, 2);

For downwards compatibility mysql_fieldname() can also be used. This is deprecated,
