PHP: the language that "everyone hates" but on which empires are built

\n\n

If you go to any developer forum and ask, "What should I write my startup in?" you risk starting a holy war. Python vs Go, JavaScript vs Rust. And almost always in this dance, the old warrior — PHP — is forgotten. People say it's a language for "business card sites" and "dinosaurs." But they're wrong.

\n\n

Let's be honest: Facebook (now Meta), Wikipedia, Etsy, Slack (in its early stages) — all of them were written in PHP. This is not a coincidence. PHP is a language that allows a startup to take off faster than you can say "Scale." In this article, we will analyze specific success stories, look at real code that helped these companies grow, and understand why PHP is still an excellent choice for an MVP and beyond.

Disclaimer: PythonLib is a site about Python, but we respect common sense. PHP is not an enemy, but a powerful tool that has solved the problems of thousands of startups. Let's study it without bias.

Why do startups choose PHP? The three pillars of success

\n\n

Before moving on to the case studies, let's break down why startup founders (especially in the early stages) are fans of PHP.

\n\n

1. Speed to Market (Time-to-Market)

In a startup, time is money. PHP allows you to write a working prototype in an evening. You don't need to set up complex architecture, write boilerplate code, or wait for compilation. Just open <?php and go.

\n\n

2. Cheap hosting and infrastructure

PHP is the king of shared hosting. While startups on Node.js or Python are forced to rent a VPS for $20 a month, a PHP project can be launched on hosting for $3. For the first 1000 users, that's more than enough.

\n\n

3. Huge community and ready-made solutions

PHP has Laravel, Symfony, Composer. These are not just frameworks — they are an ecosystem where 80% of typical tasks are already solved: authorization, payments, working with databases. You just assemble the constructor.

Story 1: Facebook — PHP that outgrew itself

\n\n

The most famous example is Facebook. Mark Zuckerberg wrote the first version of Facebook in PHP in a few weeks. The code was "dirty," but it worked and attracted users. When traffic grew to millions, Facebook engineers didn't rewrite everything in C++ (although they partially did). Instead, they created HipHop for PHP — a compiler that turned PHP code into C++, and later — HHVM (a virtual machine).

\n\n

The main lesson: PHP can scale to the skies if you approach it wisely.

\n\n

Code example: simple optimization for a startup

Let's say you're writing a news feed. A naive implementation in PHP might look like this (and it will work for 100 users):

\n\n

<?php\n// Bad example: N+1 query\n$users = $db->query("SELECT id FROM users WHERE active = 1");\nforeach ($users as $user) {\n    $posts = $db->query("SELECT * FROM posts WHERE user_id = {$user['id']}");\n    // ... output\n}\n?>

\n\n

For a startup, this is fine at the start. But as soon as you have 10,000 users — everything will crash. The right way (which Facebook uses in its internal tools):

\n\n

<?php\n// Good example: one query\n$posts = $db->query("\n    SELECT p.*, u.name \n    FROM posts p \n    JOIN users u ON p.user_id = u.id \n    WHERE u.active = 1\n    ORDER BY p.created_at DESC\n");\n?>

\n\n

Conclusion: Don't be afraid to write "bad" code at the start. The main thing is to launch and start collecting data. Optimization will come later.

Story 2: Etsy — how PHP helped artisans earn billions

\n\n

Etsy is a marketplace for handmade goods. The site is entirely written in PHP (now using Symfony). When Etsy was growing, they faced the problem of "dirty" code. But instead of rewriting everything in Python or Ruby, they hired engineers who refactored the PHP code.
