将其复制到任何 JSON 验证器中，您将看到它是有效的。

但是，当我json_decode();在 PHP 中运行此字符串时，它会静默失败。运行echo json_last_error();时返回的错误代码是4. 这对应于语法错误。

通过在我的代码编辑器中简单地查找替换\，\\我可以让它工作，但我怎样才能让 PHP 自动做到这一点？

编辑：正如在评论中发现的那样，我在上面发布的确切字符串在从文件中读取时可以正常工作，因为 PHP 不会尝试解析任何反斜杠等。但是，它似乎在读取时解析斜杠file_get_contents('php://input)是什么现在给我带来了问题。

您可以对变量执行此操作：

$json = str_replace('\\', '\\\\', $json);
