Class Phalcon\Config

Source on GitHub

Namespace Phalcon
Uses Phalcon\Collection, Phalcon\Config\Exception
Extends Collection

Phalcon\Config is designed to simplify the access to, and the use of, configuration data within applications. It provides a nested object property based user interface for accessing this configuration data within application code.

$config = new \Phalcon\Config(
    [
        "database" => [
            "adapter"  => "Mysql",
            "host"     => "localhost",
            "username" => "scott",
            "password" => "cheetah",
            "dbname"   => "test_db",
        ],
        "phalcon" => [
            "controllersDir" => "../app/controllers/",
            "modelsDir"      => "../app/models/",
            "viewsDir"       => "../app/views/",
        ],
    ]
);

Constants

const DEFAULT_PATH_DELIMITER = .;

Class Phalcon\Config\Adapter\Grouped

Source on GitHub

Namespace Phalcon\Config\Adapter
Uses Phalcon\Config, Phalcon\Config\Exception, Phalcon\Factory\Exception, Phalcon\Config\ConfigFactory
Extends Config

Reads multiple files (or arrays) and merges them all together.

See Phalcon\Config\Factory::load To load Config Adapter class using ‘adapter’ option.

use Phalcon\Config\Adapter\Grouped;

$config = new Grouped(
    [
        "path/to/config.php",
        "path/to/config.dist.php",
    ]
);
use Phalcon\Config\Adapter\Grouped;

$config = new Grouped(
    [
        "path/to/config.json",
        "path/to/config.dist.json",
    ],
    "json"
);
use Phalcon\Config\Adapter\Grouped;

$config = new Grouped(
    [
        [
            "filePath" => "path/to/config.php",
            "adapter"  => "php",
        ],
        [
            "filePath" => "path/to/config.json",
            "adapter"  => "json",
        ],
        [
            "adapter"  => "array",
            "config"   => [
                "property" => "value",
            ],
        ],
    ],
);

Methods

public function __construct( array $arrayConfig, string $defaultAdapter = string );

Phalcon\Config\Adapter\Grouped constructor

Class Phalcon\Config\Adapter\Ini

Source on GitHub

Namespace Phalcon\Config\Adapter
Uses Phalcon\Config, Phalcon\Config\Exception
Extends Config

Reads ini files and converts them to Phalcon\Config objects.

Given the next configuration file:

[database]
adapter = Mysql
host = localhost
username = scott
password = cheetah
dbname = test_db

[phalcon]
controllersDir = "../app/controllers/"
modelsDir = "../app/models/"
viewsDir = "../app/views/"

You can read it as follows:

use Phalcon\Config\Adapter\Ini;

$config = new Ini("path/config.ini");

echo $config->phalcon->controllersDir;
echo $config->database->username;

PHP constants may also be parsed in the ini file, so if you define a constant as an ini value before calling the constructor, the constant’s value will be integrated into the results. To use it this way you must specify the optional second parameter as INI_SCANNER_NORMAL when calling the constructor:

$config = new \Phalcon\Config\Adapter\Ini(
    "path/config-with-constants.ini",
    INI_SCANNER_NORMAL
);

Methods

public function __construct( string $filePath, mixed $mode = null );

Ini constructor.

protected function cast( mixed $ini ): bool | null | double | int | string;

We have to cast values manually because parse_ini_file() has a poor implementation.

protected function parseIniString( string $path, mixed $value ): array;

Build multidimensional array from string

Class Phalcon\Config\Adapter\Json

Source on GitHub

Namespace Phalcon\Config\Adapter
Uses Phalcon\Config
Extends Config

Reads JSON files and converts them to Phalcon\Config objects.

Given the following configuration file:

{"phalcon":{"baseuri":"\/phalcon\/"},"models":{"metadata":"memory"}}

You can read it as follows:

use Phalcon\Config\Adapter\Json;

$config = new Json("path/config.json");

echo $config->phalcon->baseuri;
echo $config->models->metadata;

Methods

public function __construct( string $filePath );

Phalcon\Config\Adapter\Json constructor

Class Phalcon\Config\Adapter\Php

Source on GitHub

Namespace Phalcon\Config\Adapter
Uses Phalcon\Config
Extends Config

Reads php files and converts them to Phalcon\Config objects.

Given the next configuration file:

<?php

return [

        "username" => "scott",

        "modelsDir"      => "../app/models/",
        "viewsDir"       => "../app/views/",
    ],
];

echo $config->database->username;

Methods

Given the following configuration file:

phalcon:
  baseuri:        /phalcon/
  controllersDir: !approot  /app/controllers/
models:
  metadata: memory

You can read it as follows:

define(
    "APPROOT",
    dirname(__DIR__)
);

use Phalcon\Config\Adapter\Yaml;

$config = new Yaml(
    "path/config.yaml",
    [
        "!approot" => function($value) {
            return APPROOT . $value;
        },
    ]
);
