mysql_field_name

Get the name of the specified field in a result (PHP 3, PHP 4 )
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.

Note:

Field names returned by this function are case-sensitive.

Example 601. mysql_field_name() example

<?php
/* The users table consists of three fields:
*   user_id
*   username
*   password.
*/
$link = mysql_connect('localhost', "mysql_user", "mysql_password");
$dbname = "mydb";
mysql_select_db($dbname, $link)
   or die(
"Could not set $dbname: " . mysql_error());
$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.
