Test using WordPress Playground

The changes in this pull request can previewed and tested using a WordPress Playground instance.

WordPress Playground is an experimental project that creates a full WordPress instance entirely within the browser.

Some things to be aware of

• The Plugin and Theme Directories cannot be accessed within Playground.
• All changes will be lost when closing a tab with a Playground instance.
• All changes will be lost when refreshing the page.
• A fresh instance is created each time the link below is clicked.
• Every time this pull request is updated, a new ZIP file containing all changes is created. If changes are not reflected in the Playground instance,
  it's possible that the most recent build failed, or has not completed. Check the list of workflow runs to be sure.

For more details about these limitations and more, check out the Limitations page in the WordPress Playground documentation.

If using extension_loaded('opcache'), the result is always false even if it's set to 1. The only time it works is if I use extension_loaded('Zend OPcache'). It's giving mixed results so I'm not sure which one should be more reliable as this could go down per hosting choices.

The question is, should we do a more robust approach by using function_exists( 'opcache_get_status' ) instead and ditch extension_loaded()? This will sacrifice the Is the OPcache extension available? info though.

Hey @westonruter - if you can give advice/opinion, that would be great. Thanks in advance..

I haven't done much with Opcode Cache internals, so I don't have a lot to add. But it seems like using function_exists( 'opcache_get_status' ) is best. The specific extension which enables Opcode Cache would be nice to have as additional information, but now it would most likely always be "Zend OPcache". I'm guessing you'd have to have a list of possible such extensions in an array of strings to test for all of them to see if they are available. So I think there would be two entries:

• Is Opcode Cache enabled?
• Which Opcode Cache extension is being used?

I think this also needs a Site Health test. A site without Opcode Cache should be flagged to users as a performance problem.
