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.
注:
field_index starts at 0.
e.g. The index of the third field would actually be
2, the index of the fourth field would be 3 and so
on.

or die("Could not set $dbname: " . mysql_error());
$res = mysql_query("select * from users", $link);
echo mysql_field_name($res, 0) . "\n";

mysql_fieldname() can also be used. This is deprecated,
however.
