function ContainerBuilder::compile

Compiles the container.

This method passes the container to compiler passes whose job is to manipulate and optimize the container.

The main compiler passes roughly do four things:

• The extension configurations are merged;
• Parameter values are resolved;
• The parameter bag is frozen;
• Extension loading is disabled.

Parameters

bool $resolveEnvPlaceholders Whether %env()% parameters should be resolved using the current: env vars or be replaced by uniquely identifiable placeholders. Set to "true" when you want to use the current ContainerBuilder directly, keep to "false" when the container is dumped instead.
