fbsql_list_fields — List FrontBase result fields

说明

fbsql_list_fields ( string $database_name , string $table_name [, resource $link_identifier ] ) : resource

Retrieves information about the given table.

参数

database_name

The database name.

table_name

The table name.

link_identifier

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。

返回值

Returns a result pointer which can be used with the fbsql_field_xxx functions, or false on error.

错误／异常

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.

范例

Example #1 fbsql_list_fields() example

<?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) . "\n";;}?>

以上例程的输出类似于：

field1
field2
field3
...
