  • (string) Incremental ID per prefix.
Definiert in:
Codex:

Generates an incremental ID that is independent per each different prefix.

It is similar to wp_unique_id, but each prefix has its own internal ID counter to make each prefix independent from each other. The ID starts at 1 and increments on each call. The returned value is not universally unique, but it is unique across the life of the PHP process and it's stable per prefix.
