# fbsql_list_fields

(PHP 4 >= 4.0.6)

fbsql_list_fields -- List FrontBase result fields

## Description

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

fbsql_list_fields() retrieves information about the given tablename. Arguments are the database name and the table name. A result pointer is returned which can be used with fbsql_field_flags(), fbsql_field_len(), fbsql_field_name(), and fbsql_field_type().

A result identifier is a positive integer. The function returns -1 if a error occurs. 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.

Beispiel 1. fbsql_list_fields() example

    $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";;
    }

The above example would produce the following output:

    field1
    field2
    field3
    ...
