# bcompiler_write_function

(PECL)

bcompiler_write_function -- Writes an defined function as bytecodes

## Description

bool bcompiler_write_function ( resource filehandle, string functionName )

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

This 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).

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); ?>`
