Blazing-fast JSON encoding and decoding for PHP, powered by the simdjson project. This is a fork of JakubOnderka/simdjson_php (which is a fork of crazyxman/simdjson_php) Since the simdjson PECL extension seems to be unmaintained, or at least slow to accept PRs for improvements, we packaged this up under a new name (simdjson_plus) to avoid naming conflicts and published it on Packagist (instead of PECL) for easier installation. It's a drop-in replacement for the PECL extension, with additional features from JakubOnderka, such as accelerated JSON encoding (not just decoding) and optimizations.

Ubuntu/Debian:

sudo apt-get update
sudo apt-get install php-pear php-dev build-essential

macOS, Ubuntu/Debian:

cd /tmp
git clone https://github.com/ColinHoford/simdjson-plus-php-ext.git
cd simdjson-plus-php-ext

phpize83
./configure --with-php-config=/usr/bin/php-config83
make
make install

Edit your php.ini and ensure the following line is present:

extension=simdjson_plus.so

Verify Extension Loaded

php -m | grep simdjson

Expected output:

simdjson_plus

Restart your web server and PHP-FPM:

Ubuntu/Debian:

sudo systemctl restart php8.3-fpm
sudo systemctl restart nginx

macOS:

brew services stop php@8.3
brew services start php@8.3
brew services info php@8.3

brew services stop nginx
brew services start nginx
brew services info nginx

Enable JSON optimization in your .env file:

JSON_OPTIMIZATION_DECODE=true

Instead of using json_*() directly, use the wrapper:

use ProcessMaker\Support\JsonOptimizer;

$data = JsonOptimizer::decode($json);

Or, if you’ve added a global helper:

$data = json_optimize_decode($json);

The optimizer will automatically use simdjson_plus if available, and fall back to json_decode otherwise.
