所有键都是双引号.
整个元素是一个对象.
Firefox运行良好,但Chrome报告“无效的 JSON”.为什么？

编辑：Chrome(FirebugLite)的JSON输出：
{"code":0,"data":[{"album_id":42,"album_name":"Best album","album_type":"photo","create_date":"09-05-2011 5:48:40","album_cover":"\/x\/media\/6.jpg","description":"Something here"},{"album_id":56,"album_name":"Test album","create_date":"09-05-2011 19:27:50","album_cover":"\/x\/media\/44227440_2f1f369517.jpg","description":"apples"},{"album_id":59,"album_name":"Album for something","create_date":"10-05-2011 16:19:03","album_cover":"\/x\/media\/apple-howto.jpg","description":"zzz"},{"album_id":62,"album_name":"Vietnam - Thailand - AFF Suzuki cup 2007","create_date":"17-05-2011 14:30:32","album_cover":"\/x\/media\/pwjps1231986828.jpg","description":""},{"album_id":63,"album_name":"CS","create_date":"17-05-2011 15:24:01","album_cover":"\/x\/media\/apple-logo.jpg",{"album_id":64,"album_name":"It works","create_date":"17-05-2011 15:24:56","album_cover":"\/x\/media\/it_works.png","description":""}]}
Firefox(Firebug)的JSON输出：
{"code":0,"description":""}]}
我用http://jsonlint.com/检查它,它说“有效的JSON”

您在PHP文件的开头有一个Unicode
Byte Order Mark.因此,并且因为它在开始之前<？PHP,它会在您的JSON开头发送到客户端.这将使您的JSON无效,因为这些字符不应出现在JSON数据的开头.有些浏览器可以很好地应对它;其他浏览器,如Chrome,更麻烦和抱怨. 通过保存文件而不在编辑器中设置该选项来删除字节顺序标记(如何执行此操作取决于编辑器)将解决您的问题. (您可能还会发现header()和其他发送标头的PHP函数也无法在您的PHP文件中运行,为您提供输出已经启动的错误,因为BOM将在您的PHP之前发送开始被解释.)
