# fbsql_list_fields

(PHP 4 >= 4.0.6, PHP 5)

fbsql_list_fields -- List FrontBase result fields

## Beschreibung

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

Retrieves information about the given table.

## Parameter Liste

`database_name`

  The database name.

`table_name`

  The table name.

`link_identifier`

  A FrontBase link identifier returned by fbsql_connect() or fbsql_pconnect().

  If optional and not specified, the function will try to find an open link to the FrontBase server and if no such link is found it will try to create one as if fbsql_connect() was called with no arguments

## Rückgabewerte

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

## Errors/Exceptions

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.

## Beispiele

Beispiel 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";; } ?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    field1
    field2
    field3
    ...
