<p>some time i trying to decode my own general file
that contain the all important functions in a class
but i think

<pre><code>class A {
  public function test($value){
</code></pre>

<p>and the file encoded</p>

<p>may be some one do that</p>

<pre><code>class B extends A {
  public function test($value){
