htmlspecialchars（）期望参数1是字符串，对象在COdeIgniter中给出错误 [英] htmlspecialchars() expects parameter 1 to be string, object given error in COdeIgniter

问题描述

将类型转换数组分配给codeigniter的会话时，会出现以下错误：

When assigning a type casted array to codeigniter's session, I get this error:

A PHP Error was encountered 
Severity: Warning

Message: htmlspecialchars() expects parameter 1 to be string, object given

Filename: libraries/Profiler.php

Line Number: 514

有问题的代码：

$guest = array('email' => 'empty', 'username' => 'Guest');
$this->session->set_userdata(array('current_user' => (object)$guest));

推荐答案

CodeIgniter分析器会在您存储任何非 - 在其会话中列出非字符串：

The CodeIgniter profiler breaks as soon as you store any non-array non-strings in its session:

foreach ($this->CI->session->all_userdata() as $key => $val)
{
    if (is_array($val))
    {
        $val = print_r($val, TRUE);
    }

    $output .= "<...>".htmlspecialchars($val)."<...>\n";
}

（从 CI_Profiler :: _ compile_session_data code>）

(from CI_Profiler::_compile_session_data())

这看起来像一个很愚蠢的事情，因为 print_r（）因此 is_array（$ val）|| is_object（$ val）会更合适。

This looks like a pretty stupid thing since print_r() works fine with objects - so is_array($val) || is_object($val) would be more appropriate.
