# Processing One Billion Rows in PHP!

**[DEV](https://daily.dev/sources/devto)** · 8 min read · 186 upvotes · 5 comments

## Summary

This post discusses the author's experience in optimizing a PHP script to process one billion rows of data. The initial naive implementation took 25 minutes to run, but through various optimizations, the runtime was reduced to 27.7 seconds. The optimizations included using fgets() instead of fgetcsv(), using references where possible, adding type casts, enabling JIT, and implementing multithreading.

> Great article in showing PHP's capabilities and developers who believe PHP is obsolete either lack awareness of its capabilities or are simply conforming to the trend of favoring the most widely used languages.
