Codeigniter会话信息

What is the pattern used by CodeIgniter to store session values on the database? I thought it was only a CodeIgniter way to store it but I just found another PHP projet (not using CI) that uses the same pattern.

a:11:
{
s:10:"usuario_id";
s:1:"1";
s:13:"usuario_login";
s:5:"admin";
s:13:"usuario_senha";
s:40:"8cb2237d0679ca88db6464eac60da96345513964";
s:12:"usuario_nome";
s:13:"Administrador";
s:13:"usuario_email";
s:26:"desenvolvedor.01@gmail.com";
s:18:"usuario_registrado";
s:19:"2011-05-06 16:25:33";
s:13:"usuario_chave";
s:0:"";
s:14:"usuario_status";
s:1:"1";
s:14:"usuario_logado";

b:1;
s:8:"setor_id";
s:6:"images";
s:12:"setor_numero";
s:3:"017";
}

CodeIgniter用于在数据库上存储会话值的模式是什么? 我认为它只是一种CodeIgniter方式 存储它但我刚发现另一个使用相同模式的PHP项目(不使用CI)。

  a:11:
 {
s:10:“usuario_id”  ; \ NS:1: “1”; \ NS:13: “usuario_login”; \ NS:5: “管理员”; \ NS:13: “usuario_senha”; \ NS:40: “8cb2237d0679ca88db6464eac60da96345513964”; \ NS:12  : “usuario_nome”; \ NS:13: “Administrador”; \ NS:13: “usuario_email”; \ NS:26: “desenvolvedor.01@gmail.com”; \ NS:18: “usuario_registrado”; \ NS:  19:“2011-05-06 16:25:33”; 
s:13:“usuario_chave”; 
s:0:“”; 
s:14:“usuario_status”; 
s:1:“1”;  \ NS:14: “usuario_logado” 
 \ NB:1; \ NS:8: “setor_id”; \ NS:6: “图像”; \ NS:12: “setor_numero”; \ NS:3:“017  “; 
}

    That is what happens when you call serialize on something in PHP.

    Serialize documentation:

    Generates a storable representation of a value

    This is useful for storing or passing PHP values around without losing their type and structure.

    To make the serialized string into a PHP value again, use unserialize().

    As a note, "storable", here, means "String" (I believe in all cases)

    To get a better idea as to what's in there:

    a:11: // <-- array has 11 keys (this will alternate key/value
    {
    s:10:"usuario_id"; // <-- string 10 characters long which is the first key
    s:1:"1"; // <-- string 1 character long which represents the first value
    s:13:"usuario_login"; // <-- string 13 characters long (second key)
    s:5:"admin";// <-- string 5 characters long (second value)
    // yada yada
    s:14:"usuario_logado";
    b:1; // <-- boolean TRUE
    // yada yada
    }
