mysql_field_name
(PHP 3, PHP 4)
Description
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.
蛁: 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.
瞰赽 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: ". 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.
