# mysql_field_name

(PHP 3, PHP 4 )

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.
     */
    $link = mysql_connect('localhost', "mysql_user", "mysql_password");
    mysql_select_db($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.
