# mysql_field_name

(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)

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.

> Note: `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.

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);
The above example would produce the following output:
    user_id
    password

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