>PHP natively allows for autovivification (auto-creation of arrays from falsey values). This feature is very useful and used in a lot of PHP projects, especially if the variable is undefined. However, there is a little oddity that allows creating an array from a `false` and `null` value. The above quote is from the PHP 8.1 RFC and the (accepted) RFC changes the behaviour described above to deprecated auto creation of arrays from `false`. As it is deprecated, it _will_ still work for the time being, but as of PHP 9.0, this will become a Fatal Error, so we may as well fix it now. The `recurse_dirsize()` function retrieves a transient and places it in the `$directory_cache` variable, but the `get_transient()` function in WP returns `false` when the transient doesn't exist, which subsequently can lead to the above mentioned deprecation notice. By verifying that the `$directory_cache` variable is an array before assigning to it and initializing it to an empty array, if it's not, we prevent the deprecation notice, as well as harden the function against potentially corrupted transients where this transient would not return the expected array format, but some other variable type. Includes adding dedicated unit tests for both the PHP 8.1 issue, as well as the hardening against corrupted transients. Includes some girl-scouting: touching up a parameter description and some code layout.

WordPress is a very special project to me. Every developer and contributor adds something unique to the mix, and together we create something beautiful that I’m proud to be a part of. Thousands of hours have gone into WordPress, and we’re dedicated to making it better every day. Thank you for making it part of your world.</p> <p style="text-align: right">— Matt Mullenweg</p> <h2>Installation: Famous 5-minute install</h2> <ol> <li>Unzip the package in an empty directory and upload everything.</li> <li>Open <span class="file"><a href="wp-admin/install.php">wp-admin/install.php</a></span> in your browser. It will take you through the process to set up a <code>wp-config.php</code> file with your database connection details. <ol> <li>If for some reason this doesn’t work, don’t worry. It doesn’t work on all web hosts. Open up <code>wp-config-sample.php</code> with a text editor like WordPad or similar and fill in your database connection details.</li> <li>Save the file as <code>wp-config.php</code> and upload it.</li> <li>Open <span class="file"><a href="wp-admin/install.php">wp-admin/install.php</a></span> in your browser.</li> </ol> </li> <li>Once the configuration file is set up, the installer will set up the tables needed for your site. If there is an error, double check your <code>wp-config.php</code> file, and try again. If it fails again, please go to the <a href="https://wordpress.org/support/forums/">WordPress support forums</a> with as much data as you can gather.</li> <li><strong>If you did not enter a password, note the password given to you.</strong> If you did not provide a username, it will be <code>admin</code>.</li> <li>The installer should then send you to the <a href="wp-login.php">login page</a>. Sign in with the username and password you chose during the installation. If a password was generated for you, you can then click on “Profile” to change the password.</li> </ol> <h2>Updating</h2> <h3>Using the Automatic Updater</h3> <ol> <li>Open <span class="file"><a href="wp-admin/update-core.php">wp-admin/update-core.php</a></span> in your browser and follow the instructions.</li> <li>You wanted more, perhaps? That’s it!</li> </ol> <h3>Updating Manually</h3> <ol> <li>Before you update anything, make sure you have backup copies of any files you may have modified such as <code>index.php</code>.</li> <li>Delete your old WordPress files, saving ones you’ve modified.</li> <li>Upload the new files.</li> <li>Point your browser to <span class="file"><a href="wp-admin/upgrade.php">/wp-admin/upgrade.php</a>.</span></li> </ol> <h2>Migrating from other systems</h2> <p>WordPress can <a href="https://wordpress.org/support/article/importing-content/">import from a number of systems</a>.
