# bcompiler_write_function

(PECL)

bcompiler_write_function -- Writes an defined function as bytecodes

## 说明

bool bcompiler_write_function ( resource filehandle, string functionName )

Reads the bytecodes from PHP for an existing function, and writes them to the open file handle. Order is not important, (eg. if function b uses function a, and you compile it like the example below, it will work perfectly OK).

## 参数

`filehandle`

  A file handle as returned by fopen().

`functionName`

  The function name, as a string.

## 返回值

如果成功则返回 `TRUE`，失败则返回 `FALSE`。

## 范例

例 1. bcompiler_write_function() example

`<?php $fh = fopen("/tmp/example","w"); bcompiler_write_header($fh); bcompiler_write_function($fh,"my_function_a"); bcompiler_write_function($fh,"my_function_b"); bcompiler_write_footer($fh); fclose($fh); ?>`

## 注释

警告
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。
