mysql_field_name
MYSQL_FIELD_NAME(3) 1 MYSQL_FIELD_NAME(3)
mysql_field_name - Get the name of the specified field in a result
SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
omysqli_fetch_field_direct(3) [name] or [orgname]
o PDOStatement::getColumnMeta [name]
string mysql_field_name (resource $result, int $field_offset)
DESCRIPTION
mysql_field_name(3) returns the name of the specified field index.
o $
result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).
o $
field_offset -The numerical field offset. The $field_offset starts at 0. If $field_offset does not exist, an error of level
E_WARNING is also issued.
The name of the specified field index on success or FALSE on failure.
Example #1
mysql_field_name(3) example
<?php
/* The users table consists of three fields:
* user_id
* username
* password.
*/
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect to MySQL server: ' . mysql_error());
}
$dbname = 'mydb';
$db_selected = mysql_select_db($dbname, $link);
if (!$db_selected) {
die("Could not set $dbname: " . mysql_error());
}
$res = mysql_query('select * from users', $link);
echo mysql_field_name($res, 0) . "
";
echo mysql_field_name($res, 2);
?>
The above example will output:
user_id
password
Note
Field names returned by this function are case-sensitive.

For backward compatibility, the following deprecated alias may be used: mysql_fieldname(3)
mysql_field_type(3), mysql_field_len(3).
