PHP Integration
You can use Vae PHP integration to access your Vae content through the PHP programming language.
PHP integration may be used on any page named with a .php extension or
inside any VaeML page inside the <v:php> VaeML tag. The API is
available in all pages automatically and you do not need to include any
special tags or include any libraries.
PHP Integration API
The PHP Integration API is a collection of PHP functions that allow you to access and update your Vae data. Vae’s PHP integration provides access to all of your data, but not necessarily with the same ease or finesse as VaeML.
We think that almost anything is doable within VaeML, but we provide the PHP Integration API as a fallback to ensure that we can handle any situation.
If you are reading this guide straight through, it is probably worth skimming through each function to see all the things that are possible in the PHP Integration API. Beyond that, it is mostly useful as a reference.
Building Vae Extensions with PHP
The Vae PHP Integration API also provides some functions that enable you to build extensions to the VaeML parser. You can actually create your own VaeML tags, VaeQL functions, and callback hooks that run when different events happen.
This is done by calling by registering a PHP function with Vae that will get called at the appropriate time (when a tag is ready to be rendered, the VaeQL function needs to be run, or a specific event happened).
To register code to execute when an event happens, use
vae_register_hook(). To define a new VaeML tag, use
vae_register_tag().
We used to support another function called vae_register_func() to
register a function that could be used in VaeQL, but it is no longer
necessary. All PHP functions are now made available to VaeQL
automatically.
