## What it is
A Symfony polyfill component that backports PHP 7.0 features such as intdiv, preg_replace_callback_array, random_bytes/random_int, and *Error classes to older PHP 5 versions. It lets developers write portable code that runs on both PHP 5 and PHP 7.

## Use cases
- backport php 7.0 functions to php 5
- write code portable between php5 and php7
- use random_bytes and random_int on old php
- shim *Error throwable classes in php 5
- make a library compatible with older php versions

## When to choose
- your code must run on PHP 5.x but uses PHP 7.0 features
- you maintain a library supporting a wide range of PHP versions

## When to avoid
- you only target PHP 7.0 or newer
- you need polyfills for other PHP versions (use the matching polyfill package)

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, developer-tools
- domain: developer-tools, programming-languages, cross-platform
- platform: php
- tags: polyfill, php7, compatibility-shim, backport, symfony-component
