# bcompiler_write_function

(PECL bcompiler:0.5-0.8)

bcompiler_write_function — Writes an defined function as bytecodes

### Description

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).

### Parameters

`filehandle`

  A file handle as returned by fopen().

`functionName`

  The function name, as a string.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example#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);
?>`
