Phalcon Config

Config\Adapter\Grouped

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

See Phalcon\Config\ConfigFactory::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

__construct()

public function __construct(
    array $arrayConfig,
    string $defaultAdapter = "php",
    ConfigFactory $factory = null
);

Phalcon\Config\Adapter\Grouped constructor

Config\Adapter\Ini

Reads ini files and converts them to Phalcon\Config\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
);

Method Summary

Methods

__construct()

public function __construct(
    string $filePath,
    int $mode = 1
);

Ini constructor.

cast()

protected function cast( mixed $ini ): mixed;

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

Note: this casting is an ini-format compensation and is deliberately specific to this adapter. Ini files carry untyped strings, so on/yes/true, off/no/false, null and numeric strings are decoded here. The json, yaml and php adapters receive natively typed values from their parsers and perform no casting.

castArray()

protected function castArray( array $ini ): array;

parseIniString()

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

Build multidimensional array from string

Config\Adapter\Json

Reads JSON files and converts them to Phalcon\Config\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;

return [
    "database" => [

        "host"     => "localhost",
        "username" => "scott",

    ],

Config\Adapter\Yaml

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

Given the following configuration file:

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

You can read it as follows:

    "APPROOT",
    dirname(__DIR__)
);

use Phalcon\Config\Adapter\Yaml;

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

Config\Config

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\Config(
    [
        "database" => [
            "adapter"  => "Mysql",
            "host"     => "localhost",
            "username" => "scott",
            "password" => "cheetah",
            "dbname"   => "test_db",
        ],
        "phalcon" => [
            "controllersDir" => "../app/controllers/",

            "viewsDir"       => "../app/views/",

    ]
);

Methods

getPathDelimiter()

public function getPathDelimiter(): string;

Gets the default path delimiter

merge()

public function merge( mixed $toMerge ): ConfigInterface;

Merges a configuration into the current one

$appConfig = new \Phalcon\Config\Config(
    [
        "database" => [
            "host" => "localhost",
        ],
    ]
);

$globalConfig->merge($appConfig);

path()

public function path(
    string $path,
    mixed $defaultValue = null,
    string $delimiter = null
): mixed;

Returns a value from current config using a dot separated path.

echo $config->path("unknown.path", "default", ".");

setPathDelimiter()

public function setPathDelimiter( string $delimiter = null ): ConfigInterface;

Sets the default path delimiter

toArray()

public function toArray(): array;

Converts recursively the object to an array

print_r(
    $config->toArray()
);

cloneEmpty()

protected function cloneEmpty( array $data = [] ): static;

Builds a new collection with the given data, carrying over the configuration of the current one. Clone-based instead of constructor-based: adapter subclasses (Ini, Json, Php, Yaml, Grouped) define file-loading constructors that are incompatible with the parent’s (array data, ...) signature, so filter(), map(), sort() and where() would otherwise fail on any adapter instance.

internalMerge()

final protected function internalMerge(
    array $source,
    array $target
): array;

Performs a merge recursively

setData()

protected function setData(
    mixed $element,
    mixed $value
): void;

Sets the collection data

Array values become nested Config objects carrying the insensitive, strictNull and type flags of this instance. The type guard is applied to leaf values only - arrays are not validated themselves; the nested Config validates its own leaves.

Config\ConfigFactory

Loads Config Adapter class using ‘adapter’ option, if no extension is provided it will be added to filePath

use Phalcon\Config\ConfigFactory;

$options = [
    "filePath" => "path/config",
    "adapter"  => "php",
];

$config = (new ConfigFactory())->load($options);
