Title: HTTP_HOST in local environment WP-CLI Last modified: May 5, 2023 --- # HTTP_HOST in local environment WP-CLI * Resolved [p15h](https://wordpress.org/support/users/prestonwordsworth/) * (@prestonwordsworth) * [3 years, 1 month ago](https://wordpress.org/support/topic/http_host-in-local-environment-wp-cli/) * ```wp-block-code PHP Warning: Undefined array key "HTTP_HOST" in /home/www/htdocs/wp-content/plugins/wp-cloudflare-page-cache/libs/html_cache.class.php on line 79 Warning: Undefined array key "HTTP_HOST" in /home/www/htdocs/wp-content/plugins/wp-cloudflare-page-cache/libs/html_cache.class.php on line 79 ``` * Dear Majumder * This issue seems to be prevalent across a host of plugins. From what I’ve read, the fix seems to be relatively straightforward: see [here](https://wordpress.org/support/topic/php-warning-undefined-array-key-http_host/) and [here](https://wordpress.org/support/topic/undefined-index-http_host-in-local-environment-wp-cli/). Could we use a solution similar to what’s proposed in the second link `if(!isset( $_SERVER['HTTPS'])) return;` ? * FYI, our own use case for WP CLI is in a setup using Linux’s crontab in place of WP Cron to run cron jobs including those for this plugin.

Returning from there when does not exist will cause many issues as the plugin is highly dependent on those values. * This is why we can’t just look elsewhere when it does not exist. The plugin uses it in many different ways in many different places. * Thread Starter [p15h](https://wordpress.org/support/users/prestonwordsworth/) * (@prestonwordsworth) * [3 years, 1 month ago](https://wordpress.org/support/topic/http_host-in-local-environment-wp-cli/#post-16719462) * Got it! So in this case it seems best to just ignore the php warnings. * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [3 years, 1 month ago](https://wordpress.org/support/topic/http_host-in-local-environment-wp-cli/#post-16719498) * Hi [@prestonwordsworth](https://wordpress.org/support/users/prestonwordsworth/), Yes just ignore the warnings… * [thartl](https://wordpress.org/support/users/hartl/) * (@hartl) * [2 years, 10 months ago](https://wordpress.org/support/topic/http_host-in-local-environment-wp-cli/#post-16956924) * Is there any better way to handle `$_SERVER['HTTP_HOST']` not beeing set, in ` html_cache.class.php`? On servers running UNIX cron, a common crontab implementation is:`* * * * * cd /sites/example.com/files/; /usr/local/bin/wp cron event run -- due-now >/dev/null 2>&1`So cron is fired via WP CLI. But the `$_SERVER` variable is not set up during WP CLI requests.Similarly, `$_SERVER['REQUEST_URI']` will not be defined, on the same line in `html_cache.class.php`.So logs for all our sites are filled with these warnings at all times.It’s not a functional problem, but makes our logs tough to navigate.This will be the case for those running SpinupWP and other server panels. * Just a thought: you are already checking for WP_CLI in the `add_current_url_to_cache()` method. Moving the WP_CLI check above the `$current_url = "{$parts...` line fixes the problem. Would that work? * Thank you! * Plugin Contributor [iSaumya](https://wordpress.org/support/users/isaumya/) * (@isaumya) * [2 years, 10 months ago](https://wordpress.org/support/topic/http_host-in-local-environment-wp-cli/#post-16959217) * Hi [@hartl](https://wordpress.org/support/users/hartl/), Can you please try out [this build of the plugin](https://verti-artifacts.s3.amazonaws.com/WP-Cloudflare-Super-Page-Cache-development-b9129a1b/wp-cloudflare-page-cache.zip) and let me know if this resolves your issue or not? * [thartl](https://wordpress.org/support/users/hartl/) * (@hartl) * [2 years, 9 months ago](https://wordpress.org/support/topic/http_host-in-local-environment-wp-cli/#post-17039636) * Hi [@isaumya](https://wordpress.org/support/users/isaumya/), Apologies about the late reply.
