README

This is just a payload map written in php. This lib helps you to get values from A structure and put it on B struscture

Note: Phmap uses illuminate/support under the hood. If you are using laravel or lumen framework, make sure that you version is >= 9.x, if you're not using any of these frameworks or this dependency(illuminate/support) , than you have nothing to worry about.

Install

Via Composer

$ composer require alexrili/phmap

Basic usage

Under the hood we provide a payload_map() helper function. The payload_map() accpets two arguments: 1º is your input data, 2º is your map config. Both needs to be array type. Let`s see the example bellow.

#can be a response from api request
$inputData = [
    'a' => 'Value from A'
];

$map = [
    'from' => 'a',
    'to' => 'b'
];

$response = payload_map($inputData, $map);
// var_dump($response);
// return will be
array:1 [
    "b" => "Value from A"
]

Now let's imagine that you have a multliple values from an array and needs to change the inside properties. With Phmap you can do that :)

# e.g: Imagine that you have the following payload

$oldPayload = [
    'addresses' => [
        [
            'mainAddress' => true,
            'address' => '54 St',
            'code' => '676329-098'
        ],
        [
            'mainAddress' => false,
            'address' => 'Saint Louis Av',
            'code' => '4432-098'
        ]
    ]
];

$map = [
    [
        'from' => 'addresses.*.address',
        'to' => 'users_addresses.*.street_name'
    ],
    [
        'from' => 'addresses.*.code',
        'to' => 'users_addresses.*.postal_code'
    ]    
];

$newPayload = payload_map($inputData, $map);
// var_dump($newPayload);
// return will be
array:2 [
     "users_addresses" => [
        [
            "street_name" => "54 St",
            "postal_code" => "676329-098"
        ],
        [
            "street_name" => "Saint Louis Av",
            "postal_code" => "4432-098
        ]
    ]
]

Notice: The mainAddress property was not in the new payload, this is happening because we're not tells the payload map to map that

Map configs

Direct values

you can map a value from a direct path in your structure just point where the values are in from key and point the destination path within to key

[
    "from" =>"a",
    "to" => "b" 
]

Concatanated values

you can concatanate one or more values using the .+. symbol

[
    "from" =>"a.a1.+.a.a2",
    "to" => "b" 
]

Fixed values

you can add some fixed values using the__()__ symbol

[
    "from" =>"__(This is a fixed value)__",
    "to" => "b" 
]

Collection(array) of values

you can map a nested property inside an array using the .*. symbol

[
    "from" =>"a.*.a1",
    "to" => "b.*.b1" 
]

One Or Antoher value

you can map two(or more) direferente paths to bring a value, then the phmap will go through all the paths until it finds a value. To make one or another value, you can use || symbol

[
    "from" =>"a||a1",
    "to" => "b" // if finds value in [a], brings [a], if not try to brings [b]
]

Nullable values

you may need to map some properties that has a null value, for that you just need to pass a string flag called nullable with one of this two values ["true"|"false"], if trues, means you want to bring this property to you new structure even if their value is null.

Default value is "false"

[
    "from" =>"a",
    "to" => "b" 
    "nullable" => "true" 
    // if [a] don't have value
    // the results will be ["b"=>null] 
]

Advanced usage

$inputData = [
    'a' => [
        [
            'ac1' => 'I`m a multilevel value'
        ],
        [
            'ac1' => 'I`m a multilevel value',
        ]
    ],
    'aDV' => 'I`m a directed value'
];

$map = [
    [
        'from' => 'a.*.ac1.+.__(I`m a fixed value)__.+.aDV',
        'to' => 'b.*.bc'
    ]
];

$response = payload_map($inputData, $map);
// var_dump($response)
// result wil be
array:1 [
  "b" => array:2 [
    0 => array:1 [
      "bc" => "I`m a multilevel valueI`m a fixed valueI`m a directed value"
    ]
    1 => array:1 [
      "bc" => "I`m a multilevel valueI`m a fixed valueI`m a directed value"
    ]
  ]
]
