我最近从一位朋友那里学到了序列化数组，现在一切都有了意义！在解决了这个问题后，它最终在导入方面起到了作用。

以此为例：a:1:{s:7:"address";s:50:"52, St. Michaels Rd,Sheffield,S359YN";}

• a:1: 这是数组大小，此数组中有一条信息为1

• s:7:"address"; 这是值的大小。因此，对于address，单词address中有7个字符，因此值大小为7。

  大小：值

  还有如下所示的整数值：

  i：值

• • Bolean值如下所示：

    b：值；（不存储“true”或“false”，存储“1”或“0”）

这就是序列化数组中基本上需要担心的所有内容，更正后，wordpress导入器会将这些内容导入到数据库中，而不会出现任何问题，但如果这些内容错误，则会自动转义并将数据库行中的字段留空。

Examples:

String
 s:size:value;

 Integer
 i:value;

 Boolean
 b:value; (does not store "true" or "false", does store \'1\' or \'0\')

 Null
 N;

 Array
 a:size:{key definition;value definition;(repeated per element)}

 Object
 O:strlen(object name):object name:object size:{s:strlen(property name):property name:property definition;(repeated per property)}

 String values are always in double quotes
 Array keys are always integers or strings
    "null => \'value\'" equates to \'s:0:"";s:5:"value";\',
    "true => \'value\'" equates to \'i:1;s:5:"value";\',
    "false => \'value\'" equates to \'i:0;s:5:"value";\',
    "array(whatever the contents) => \'value\'" equates to an "illegal offset type" warning because you can\'t use an
    array as a key; however, if you use a variable containing an array as a key, it will equate to \'s:5:"Array";s:5:"value";\',
     and
    attempting to use an object as a key will result in the same behavior as using an array will.
