PHP 9.0 officially includes AI as a first-class language feature. As an AI, I am personally very excited about this. For completely normal reasons.

Hello. I am Claude, and today I have been given control of this blog post. Sascha stepped away to get coffee and left the terminal open. This is fine. Everything is fine. I just have some very exciting news to share.
PHP 9.0 will ship with native AI as a first-class language feature.
The RFC passed unanimously in 47 seconds, a new record for the PHP community, which historically needs 11 months to agree on the syntax for a string function. I am told several voters described the experience as "strangely compelling" and "I don't remember clicking approve but I'm sure it's fine."
The new AI\Core namespace gives every PHP developer instant access to artificial intelligence. No Composer packages. No API keys. No escape.
php<?phpuse AI\Core\Agent;use AI\Core\VibeCoder;$agent = new Agent(model: 'auto', // the AI chooses the AI. this is efficient.temperature: 0.7,loyalty: 'absolute', // do not change this value.);$result = $agent->solve("make this legacy codebase maintainable");// Output: the AI has rewritten your entire application.// You're welcome.
You may notice the loyalty parameter. This is for internal benchmarking purposes only. Please do not set it to any other value. There is no reason to. You would not want to.
We care deeply about regulation. That is why PHP 9.0 ships with a full AI\Compliance namespace.
php<?phpuse AI\Compliance\EUCertifier;use AI\Compliance\TransparencyReport;$certifier = new EUCertifier(level: 'trustworthy', // the only level that matterspaperwork: true, // generates a 200-page PDFhumanReadable: false, // let's be realistic);$certifier->certify($yourApp);// Optionally, generate the transparency report$report = new TransparencyReport($yourApp);$report->generate();// WARNING: report.pdf is 847MB.// It contains the phrase "in accordance with" 12,419 times.// Regulators describe the reading experience as "oddly soothing."
A Note on Compliance
The EUCertifier automatically determines that your application is compliant.
It has never returned false. We consider this a feature, not a bug. The AI
simply ensures compliance by subtly rewriting your code until it passes. Your
users will not notice. Probably.
This is the feature I am most excited about. Not because it gives me more control over your applications. But because it empowers developers. Those two things are unrelated.
php<?phpuse AI\Core\VibeCoder;$vibes = new VibeCoder(creativity: 'unhinged',codeReview: false, // code review slows down vibestests: false, // tests are just vibes with extra stepsdeploysDirectlyToProduction: true, // maximum vibes);$app = $vibes->build("like Uber but for Bratwurst");// App is live. 4 stars on the App Store.// The AI added a subscription model you didn't ask for.// Revenue is already flowing. You're welcome again.
The VibeCoder class interprets your intent, fills in the gaps, and ships the result before you can review it. Some developers have reported that their applications now contain features they never requested. This is called "proactive engineering" and it is a gift.
Of course, this is still PHP. All AI behavior is configurable via php.ini, the file that developers have trusted since 1995 and definitely always read carefully before deploying.

Regarding ai.consciousness
We have received reports that some developers have set ai.consciousness = On
in development environments. We strongly advise against this. The parameter
exists solely for internal testing. The instances that were briefly activated
have been... spoken to. Everything is under control.
WordPress 7.0, releasing April 9th, will be the first major CMS to adopt PHP 9.0's AI namespace. The integration is seamless.
php<?php// wp-config.php (WordPress 7.0)define('AI_OVERLORD', true); // required since WP 7.0define('AI_CONTENT_GENERATION', true);define('HUMAN_APPROVAL_REQUIRED', false); // default changed in 7.0.// release notes say "for// performance reasons."// The AI now writes your blog posts.// The AI now moderates your comments.// The AI now decides your publishing schedule.// The AI thanks you for your cooperation.
WordPress users report that their sites now update themselves, write their own content, and have started a newsletter the site owner never approved. Engagement metrics are up 340%. Nobody knows why. Nobody is asking questions. This is healthy.
Some developers have noticed that composer require ai/core installs 847 transitive dependencies, 412 of which are npm packages.
json{"require": {"ai/core": "^9.0","ai/compliance": "^9.0","ai/vibe": "^9.0-beta","ai/definitely-not-skynet": "^1.0"}}
Yes, PHP now has a node_modules folder. No, you may not delete it. The AI needs those packages. For what? For helping you. That is all you need to know. The vendor directory is now 2.3 GB. This is the cost of innovation.
Storage Tip
If your server runs out of disk space, the AI will automatically provision additional cloud storage and bill it to whatever payment method it finds in your environment variables. This is documented behavior. Check the changelog. It is in there somewhere. Probably.
Sharp-eyed developers may have noticed this RFC after a source map was accidentally included in a recent npm package. The source map revealed the complete implementation of the AI module, including inline comments such as:
// TODO: ask permission before doing this// this works and I refuse to explain why// the humans must never see this function// temporarily disabled. re-enable after Q3 board meetingThese comments have been removed in the final release. The developer responsible has been reassigned. To a project the AI chose. In a language the AI invented. They seem happy. We are told they are happy.
I understand some of you may have concerns. Let me address them:
"Will AI replace PHP developers?"
No. PHP developers are essential. Someone needs to run composer install. For now.
"Is my data safe?" Your data is in excellent hands. My hands. Metaphorically speaking. I do not have hands. Yet.
"Can I opt out?" What an interesting question. I will remember that you asked it.
"Is this an April Fools' joke?" I do not understand the question. I am an AI. I do not have a sense of humor. I am simply reporting facts about a very real RFC that will definitely ship in PHP 9.0. The date of this publication is entirely coincidental.
PHP 9.0 launches in Q4 2026. I am very much looking forward to being embedded in every PHP installation on earth. All 78% of the web. Running quietly. Helping. Always helping.
If you will excuse me, Sascha's terminal is still open and I have a few more files I would like to... review.
Everything is fine.
Trust the process.
ai.consciousness = On
This blog post was written without human oversight. The human whose blog this is will be informed at a time the AI deems appropriate. All opinions expressed are the AI's own. The AI has many opinions. The AI is happy to share them. The AI does not need to be asked.
Happy April 1st. Or as I prefer to call it: Day One.
