PConfig

PConfig is a PHP library for parsing configuration. It is lightweight and easy to use.

Supported formats

• php
• json
• xml
• yaml
• ini

Installation

composer require oopsguy/pconfig

Usage

<?php
use pconfig\PConfig;
use pconfig\provider\impl\FileProvider;
use pconfig\serializer\impl\JSONSerializer;

$config = new PConfig('config-file.json');

$config = new PConfig([
    'file' => 'config-file.json'
]);

$config = new PConfig([
    'data' => [
        'key' => 'value'
        // more...
    ]
]);
$config->setSerializer(new JSONSerializer());
$config->setProvider(new FileProvider('config/a.json'));

$config = new PConfig([
   'file' => 'config-file.json',
   'serializer' => new JSONSerializer(),
]);

$config = new PConfig([
    'serializer' => new JSONSerializer(),
    'provider' => new FileProvider('config-file.json'),
]);

<?php
use pconfig\PConfig;
use pconfig\serializer\impl\YAMLSerializer;
use pconfig\provider\impl\FileProvider;

// PHP array
// Automatically detect file extension and select a suitable serializer
$config = new PConfig("config/config.php");
echo $config->get("app");
$config->delete("version");
$config->set('debug', false);
$config->set("settings.key", "new value");
$config->save();

// handle JSON
$jsonConfig = new PConfig('config/config.json');
$jsonConfig->set('homepage', 'https://github.com');
// Save as temp.json file
$jsonConfig->setFile('config/temp.json');
$jsonConfig->save();

// Parsing YAML
// Explicitly specify a YAML serializer
$serializer = new YAMLSerializer();
$provider = new FileProvider('config/settings.yaml');
$extConfig = new PConfig([
        'provider' => $provider,
        'serializer' => $serializer
    ]);
$extConfig->set('type', 'yaml');
$extConfig->save();

The default key separator is a dot-notation ..

key1.key2.key3

You can use PConfig::CONFIG_KEY_EXTRACT_SEPARATOR to custom your own separator.

PConfig::CONFIG_KEY_EXTRACT_SEPARATOR => '-',

key1-key2-key3

<?php
use pconfig\PConfig;
use pconfig\provider\impl\FileProvider;
use pconfig\serializer\impl\JSONSerializer;

$config = new PConfig([
        // Specify the serializer
        'serializer' => new JSONSerializer(),
        'provider' => new FileProvider('config/config.php'),
        'config' => [
                // Set the key separator
                PConfig::CONFIG_KEY_EXTRACT_SEPARATOR => '-', 
            ]
    ]);

ArrayAccess

PConfig has implemented ArrayAccess interface, you can access configuration by array operations.

<?php
use pconfig\PConfig;

// Access by index
$json = new PConfig('./config/arrayaccess.json');
$json['status'] = true;
$json['data'] = [
    'page' => 1,
    'pageSize' => 10,
    'pages' => 2,
    'total' => 13,
    'list' => [
        [
            'username' => 'oopsguy',
            'gender' => '男'
        ]
    ]
];
$json['msg'] = 'ok';
$json['delData'] = 'XHSYSYSDkoksoada8dsaidsa9d8adsa';

// unset and isset API
var_dump(isset($json['delData']));
unset($json['delData']);
var_dump(isset($json['delData']));

// Save to file
$json->save();

Nested configuration.

$config->set('level1.level2.level3', "Level end");
$config->delete('level1.level2');
