# ExtraPack

> Extras for pack() and unpack() functions.

# Install

```text

composer require ddrv/extra-pack

```

```php

 'string',

    'key2' => 5,

    'key3' => .0001

);

$format = 'A6key1/Ckey2/t4key3';

$binary = \Ddrv\Extra\Pack::pack($format, $data);

$result = \Ddrv\Extra\Pack::unpack($format, $binary);

print_r($result);

```

```text

Array

(

    [key1] => string

    [key2] => 5

    [key3] => .0001

)

```

# Format

```text

character[+number]+key[+:added]

```

Elements are separated by a slash

Examples:

|Format|Key|Result|

|---|---|---|

|A6name|name|string with length 6|

|Coffset:2000|offset|Number from 0 to 255 + 2000|
