Devium/Toml

A robust and efficient PHP library for encoding and decoding TOML compatible with v1.0.0

This library tries to support the TOML specification as much as possible.

Overview

This library provides a comprehensive solution for working with TOML in PHP applications

Features

• Encoding PHP arrays and objects to TOML format
• Decoding TOML strings into PHP data structures
• Preserves data types as specified in TOML
• Handles complex nested structures
• Supports TOML datetime formats
• Error handling with informative messages

Installation

You can install this library via composer:

composer require devium/toml

Usage

Decoding:

$toml = <<<TOML

# This is a TOML document

title = "TOML Example"

[owner]
name = "Tom Preston-Werner"
dob = 1979-05-27T07:32:00-08:00

TOML;

dump(\Devium\Toml\Toml::decode($toml, asArray: true));
dump(\Devium\Toml\Toml::decode($toml, asArray: false));

// or use global helper
dump(toml_decode($toml, asArray: false));
dump(toml_decode($toml, asArray: true));

Encoding:

$data = [
  "title" => "TOML Example",
  "owner" => [
    "name" => "Tom Preston-Werner",
    "dob" => "1979-05-27T15:32:00.000Z",
  ],
];

dump(\Devium\Toml\Toml::encode($data));
// or use global helper
dump(toml_encode($data));

About TOML datetime formats

This library tries to parse TOML datetime formats into next variants (according to the specification):

• Devium\Toml\TomlDateTime (for the offset date time)
• Devium\Toml\TomlLocalDatetime (for the local date time)
• Devium\Toml\TomlLocalDate (for the local date)
• Devium\Toml\TomlLocalTime (for the local time)

Example:

offset-date-time-1 = 1979-05-27T07:32:00Z
offset-date-time-2 = 1979-05-27T00:32:00-07:00
offset-date-time-3 = 1979-05-27T00:32:00.999999-07:00
offset-date-time-4 = 1979-05-27 07:32:00Z

local-date-time-1 = 1979-05-27T07:32:00
local-date-time-2 = 1979-05-27T00:32:00.999999

local-date-1 = 1979-05-27

local-time-1 = 07:32:00
local-time-2 = 00:32:00.999999

If you use

dump(toml_decode($toml, true));

TOML will be parsed into array

array:9 [
  "offset-date-time-1" => Devium\Toml\TomlDateTime @296638320 {#29
    date: 1979-05-27 07:32:00.0 +00:00
  }
  "offset-date-time-2" => Devium\Toml\TomlDateTime @296638320 {#35
    date: 1979-05-27 00:32:00.0 -07:00
  }
  "offset-date-time-3" => Devium\Toml\TomlDateTime @296638320 {#41
    date: 1979-05-27 00:32:00.999999 -07:00
  }
  "offset-date-time-4" => Devium\Toml\TomlDateTime @296638320 {#47
    date: 1979-05-27 07:32:00.0 +00:00
  }
  "local-date-time-1" => Devium\Toml\TomlLocalDateTime {#55
    +year: 1979
    +month: 5
    +day: 27
    +hour: 7
    +minute: 32
    +second: 0
    +millisecond: 0
  }
  "local-date-time-2" => Devium\Toml\TomlLocalDateTime {#61
    +year: 1979
    +month: 5
    +day: 27
    +hour: 0
    +minute: 32
    +second: 0
    +millisecond: 999
  }
  "local-date-1" => Devium\Toml\TomlLocalDate {#59
    +year: 1979
    +month: 5
    +day: 27
  }
  "local-time-1" => Devium\Toml\TomlLocalTime {#70
    +millisecond: 0
    +hour: 7
    +minute: 32
    +second: 0
  }
  "local-time-2" => Devium\Toml\TomlLocalTime {#77
    +millisecond: 999
    +hour: 0
    +minute: 32
    +second: 0
  }
]

Each class implements Stringable interface.

TomlLocal* classes are marked with TomlDateTimeInterface for usability. Each class has public properties.

There is TomlDateTime class to support TOML offset date time format also.

Of course any DateTimeInterface or TomlDateTimeInterface are encoded into TOML datetime string. So

$data = [
    'DateTimeInterface' => new DateTimeImmutable('1979-05-27T07:32:00Z'),
    'TomlDateTimeInterface' => new TomlDateTime('1979-05-27T07:32:00Z'),
];

will be encoded into

DateTimeInterface = 1979-05-27T07:32:00.000Z
TomlDateTimeInterface = 1979-05-27T07:32:00.000Z

About informative errors

If there is parsing error, TomlError has the approximate location of the problem in the message. Something like:

Invalid TOML document: unexpected non-numeric value

5:  [owner]
6:  name = Tom Preston-Werner
             ^
7:  dob = 1979-05-31T07:32:00-08:00

Else it has message about whole input.

About floating-point values

The decoder returns each floating-point value as a string by default.

You can force it to return a float type by setting the $asFloat argument:

toml_decode($toml, asFloat: true);
// or
\Devium\Toml\Toml::decode($toml, asFloat: true);

About NULL

TOML does not support null values.

If the array contains a null value, an exception will be thrown.

The only thing possible is a null value for the keys in the tables. Such keys are simply skipped during encoding.
