phP Serialize() To {JSON|YAML|TOML}

Web and CLI tool are available!

Warning

Use it for easy human checking.

Converts data serialized by the PHP serialize function into some format (JSON or YAML or TOML for now).
This may be useful if you want to convert the payload string stored in the Laravel job queue 👍
If you find a bug or have a request, please create issue or Pull Request!

Web 👉 https://ddddddo.github.io/ps2/
Conversion can be done offline as it is processed in Wasm.

Install

Homebrew

brew install ddddddO/tap/ps2

Go

go install github.com/ddddddO/ps2/cmd/ps2@latest

Usage

Format:

$ ps2 <<< '< Data serialized by PHP serialize function >'

• Use <<< or printf to pass serialized data to stdin, since using echo as in echo 'O:13:"App\UpdateJob....' | ps2 may cut off the \U part.

Example serialized data:

O:13:"MySimpleClass":17:{s:10:"publicProp";s:16:"Top Level Object";s:26:"MySimpleClassprivateProp";i:999;s:16:"*protectedProp";a:3:{s:10:"assoc_key1";s:12:"assoc_value1";s:10:"assoc_key2";i:789;s:17:"deep_nested_array";a:2:{s:9:"sub_key_x";s:11:"sub_value_x";s:9:"sub_key_y";d:12.34;}}s:6:"parent";N;s:15:"nestedArrayData";a:5:{i:0;s:6:"Item A";i:1;s:6:"Item B";i:2;s:6:"Item C";i:3;i:10;i:4;b:0;}s:16:"sharedStringRef1";s:33:"共有される文字列データ";s:16:"sharedStringRef2";R:17;s:16:"sharedObjectRef1";O:13:"MySimpleClass":6:{s:10:"publicProp";s:24:"共通オブジェクト";s:26:"MySimpleClassprivateProp";i:500;s:16:"*protectedProp";a:1:{s:6:"shared";b:1;}s:6:"parent";N;s:15:"nestedArrayData";a:0:{}s:9:"nullValue";N;}s:16:"sharedObjectRef2";r:18;s:21:"customSerializableObj";O:20:"MyCustomSerializable":2:{s:1:"s";s:36:"オブジェクト内のカスタム";s:1:"n";i:777;}s:12:"userRoleEnum";E:15:"UserRole:Editor";s:10:"statusEnum";E:13:"Status:Active";s:9:"nullValue";N;s:11:"booleanTrue";b:1;s:10:"floatValue";d:45.67;s:12:"integerValue";i:123;s:14:"japaneseString";s:36:"これは日本語の文字列です";}

  phpのserialize関数でシリアライズされた文字列（元のデータは、ネストした連想配列と、配列と、適当なクラスのオブジェクトを持つ）から、astを生成するgoプログラムを教えてください。
  

  • 一発で動かない & 微調整の必要があったため手を入れている
    • 継続して手を入れ続けている
  • 生成されたコードは「Go言語でつくるインタプリタ」の内容にかなり似ている
