(PHP 4 >= 4.0.6, PHP 5, PHP 7)
fbsql_list_fields — List FrontBase result fields
$database_name
, string $table_name
[, resource $link_identifier
] ) : resourceRetrieves information about the given table.
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。
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.
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 ...
