  • fbsql_list_fields()

    (PHP 4 >= 4.0.6, PHP 5, PHP 7)

    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 thefbsql_field_xxxfunctions, 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
    ...
