var_representation_polyfill
=============================
[![Build Status](https://github.com/TysonAndre/var_representation_polyfill/actions/workflows/main.yml/badge.svg?branch=main)](https://github.com/TysonAndre/var_representation_polyfill/actions/workflows/main.yml?query=branch%3Amain)
[![License](https://img.shields.io/github/license/TysonAndre/var_representation_polyfill.svg)](https://github.com/TysonAndre/var_representation_polyfill/blob/main/LICENSE)
[![Latest Stable Version](https://img.shields.io/github/v/release/TysonAndre/var_representation_polyfill.svg)](https://packagist.org/packages/TysonAndre/var_representation_polyfill)
[var_representation_polyfill](https://github.com/TysonAndre/var_representation_polyfill) is a polyfill for https://pecl.php.net/var_representation
This provides a polyfill for the function `var_representation(mixed $value, int $flags = 0): string`, which converts a
variable to a string in a way that fixes the shortcomings of `var_export()`
See [the var_representation PECL documentation](https://github.com/TysonAndre/var_representation) for more details
Installation
------------
```
composer require tysonandre/var_representation_polyfill
```
Usage
-----
```php
// uses short arrays, and omits array keys if array_is_list() would be true
php > echo var_representation(['a','b']);
[
'a',
'b',
]
// can dump everything on one line.
php > echo var_representation(['a', 'b', 'c'], VAR_REPRESENTATION_SINGLE_LINE);
['a', 'b', 'c']
php > echo var_representation("uses double quotes: \$\"'\\\n");
"uses double quotes: \$\"'\\\n"
// Can disable the escaping of control characters as of polyfill version 0.1.0
// (e.g. if the return value needs to be escaped again)
php > echo var_representation("has\nnewlines", VAR_REPRESENTATION_UNESCAPED);
'has
newlines'
php > echo json_encode("uses single quotes:\0\r\n\$\"'\\");
"uses single quotes:\u0000\r\n$\"'\\"
php > echo json_encode(var_representation("uses single quotes:\0\r\n\$\"'\\",
VAR_REPRESENTATION_UNESCAPED));
"'uses single quotes:\u0000\r\n$\"\\'\\\\'"
```
