The client expects the array to be serialized without a string key. It's just indexed starting with `i:0`.\r\n\r\nE.g.\r\n\r\nMy class:\r\n\r\n```\r\npublic class MyClass\r\n{\r\n     // How to avoid the `objects` key prefix?\r\n    public List\u003cObjects\u003e? objects { get; set; }\r\n\r\n    [PhpProperty(\"some_string\")]\r\n    public string? some_string{ get; set; }\r\n\r\n    [PhpProperty(\"some_string2\")]\r\n    public string? some_string2{ get; set; }\r\n\r\n    [PhpProperty(\"some_string3\")]\r\n    public string? some_string3{ get; set; }\r\n\r\n    [PhpProperty(\"some_string4\")]\r\n    public string? some_string4{ get; set; }\r\n}\r\n```\r\n\r\nanother option I tried was just using an object but not a list:\r\n\r\n```\r\n     // How to have this be an integer index?\r\n    public Objects? objects { get; set; }\r\n```\r\n\r\nThe output I'm hoping to match would look like this:\r\n\r\n```\r\n// Notice the array index `0` is used without any string key\r\na:5:{i:0;a:2:\r\n```\r\n\r\nWhat I'm actually getting [List version]:\r\n\r\n```\r\na:5:{s:7:\"objects\";a:1:{i:0;a:2:\r\n```\r\n\r\nWhat I'm getting [without List version]:\r\n\r\n```\r\na:5:{s:7:\"objects\";a:2:\r\n```\r\n\r\nThanks in advance.","author":{"url":"https://github.com/mrhappyasthma","@type":"Person","name":"mrhappyasthma"},"datePublished":"2022-04-17T05:24:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":13},"url":"https://github.com/32/PhpSerializerNET/issues/32"}
