fbsql_list_fields — List FrontBase result fields
Retrieves information about the given table.
The database name.
The table name.
由 fbsql_connect() 或 fbsql_pconnect() 返回的 FrontBase 链接标识符.
如可选并未指定，函数会尝试查找一个到 FrontBase 服务器的开放链接，且如没有找到这样的链接，会尝试通过不带参数调用 fbsql_connect() 来创建一个。
Returns a result pointer which can be used with the fbsql_field_xxx functions, or FALSE on error.
A string describing the error will be placed in $phperrmsg, and unless the function was called as @fbsql() then this error string will also be printed out.

<?php
$link = fbsql_connect('localhost', 'myname', 'secret');
$fields = fbsql_list_fields("database1", "table1", $link);
$columns = fbsql_num_fields($fields);
for ($i = 0; $i < $columns; $i++) {
echo fbsql_field_name($fields, $i) . "
";;
}
?>
