# fdf_set_value

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

fdf_set_value -- Set the value of a field

## 说明

bool fdf_set_value ( resource fdf_document, string fieldname, mixed value [, int isName] )

Sets the `value` for the given field.

## 参数

`fdf_document`

  The FDF document handle, returned by fdf_create(), fdf_open() or fdf_open_string().

`fieldname`

  Name of the FDF field, as a string.

`value`

  This parameter will be stored as a string unless it is an array. In this case all array elements will be stored as a value array.

`isName`

  > 注意: In older versions of the FDF toolkit last parameter determined if the field value was to be converted to a PDF Name (= 1) or set to a PDF String (= 0).

  > The value is no longer used in the current toolkit version 5.0. For compatibility reasons it is still supported as an optional parameter beginning with PHP 4.3, but ignored internally.

## 返回值

如果成功则返回 `TRUE`，失败则返回 `FALSE`。

## 更新日志

版本 | 说明
--- | ---
4.3.0 | Support for arrays in the `value` parameter was added.
