Keys are of type string and values can be any PHP variables. APCu only supports userland caching of variables. APCu is APC stripped of opcode caching. See [APCu Backwards Compatibility Module](https://github.com/krakjoe/apcu-bc) which provides a drop in replacement for APC.

Reporting Bugs ============== [](#reporting-bugs) If you believe you have found a bug in APCu, please open an issue: Include in your report *minimal, executable, reproducing code*. Minimal: reduce your problem to the smallest amount of code possible; This helps with hunting the bug, but also it helps with integration and regression testing once the bug is fixed. Executable: include all the information required to execute the example code, code snippets are not helpful. Reproducing: some bugs don't show themselves on every execution, that's fine, mention that in the report and give an idea of how often you encounter the bug. **It is impossible to help without reproducing code, bugs that are opened without reproducing code will be closed.** Please include version and operating system information in your report. ### Health Score 53 — FairBetter than 97% of packages Maintenance78 Regular maintenance activity Popularity56 Moderate usage in the ecosystem Community36 Small or concentrated contributor base Maturity38 Early-stage or recently created project Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
