README
======

[](#readme)

This extension is to show low level PHP structures. It is therefore very sensitive to changes in the PHP API. If the PECL install doesn't work, please try the latest version from GitHub:

```
git clone https://github.com/derickr/vld.git
cd vld
phpize
./configure
make && make install
```

If it still doesn't compile, then VLD is not for you. Patches are welcome through Pull Requests.

How does it work?
-----------------

[](#how-does-it-work)

There are a few options in the form of `php.ini` settings available.

In order for VLD to do anything, you need to set `vld.active=1`.

If you want to prevent VLD from executing code, set `vld.execute=0`.

Other settings are also available, but not documented yet.

Please see the project page at  for some more information.
