【问题描述】：

如何将此 json 字符串转换为数组？我试过json_decode，但它返回null。

它以前是一个 .json 文件，我使用 file_get_contents 获取它的数据。

我也尝试过使用 foreach 循环，但 PHP 库应该可以提供答案。

我还从 stackoverflow 中查看了另一个相关主题，但没有成功。

谢谢！

【问题讨论】：

你试过了吗：json_decode($jsondata, true)？
如果您能提供Minimal, Complete, and Verifiable example，那就太好了。

标签： php html json

【解决方案1】：

您的最后一行 json 有尾随逗号 (,)，这使您的 json 无效。从

中删除该逗号

"description":"Orange shirts",

来自 jsonlint 的错误

Error: Parse error on line 123:
...: "Orange shirts",   }}
----------------------^
Expecting 'STRING', got '}'

尝试在 https://jsonlint.com/ 上验证您的 json
