PHP字符串数组转换
[英]PHP string array casting
问题描述
I'm trying to find a way to cast the following into a real array. 
我正在尝试找到一种将以下内容转换为真实数组的方法。 The data is stored as a string in the system I am working on. 数据以字符串形式存储在我正在使用的系统中。
I have tried (array) $stringArrayData; 我试过了(array) $stringArrayData; but that didn't work. 但这没用。
The string data is as follows: 字符串数据如下：

If you have the option, preferably, you should store the items individually - It will be much easier to change parts of the data, and will allow you to abstract the language you're using away from the data storage 如果可以的话，最好单独存储项目-更改部分数据会容易得多，并且可以从数据存储中抽象出使用的语言
If that's not an option, consider storing the data in a different way - Maybe serialize the data before you save it to the DB, and then unserialize it when you retrieve it. 如果不是这种选择，请考虑以其他方式存储数据-也许先序列化数据，然后再将其保存到数据库中，然后在检索时反序列化。 Unserialize keeps the data type and structure. 反序列化保留数据类型和结构。
If you can't do that, then you would probably have to parse the string and build a new array from that, or eval the entire string to a variable and then use the variable. 如果无法做到这一点，则可能必须解析字符串并从中构建一个新数组，或者将整个字符串评估为一个变量，然后使用该变量。

Try this: 尝试这个：
eval("\$array = " . $stringArrayData);
Then, 然后，
print_r($array);
