fbsql_field

说明

string fbsql_field_name ( resource result [, int field_index] )

fbsql_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.

注: 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.

例子 1. fbsql_field_name() example
<?php // The users table consists of three fields: // user_id // username // password. $res = fbsql_db_query("users", "select * from users", $link); echo fbsql_field_name($res, 0) . "\n"; echo fbsql_field_name($res, 2); ?>
上例将输出：
user_id password
