Question

这是模型：

    <?php

class Generalfeaturesmodel extends CI_Model      
{              
    protected $websitename;            

    public function __construct()                                   
    { 
        parent::__construct();
        $this->websitename = 'GameSwap';   
    } 

    // helper function that retrieves all the data from the specified table.  Basically since this is in the swap account model
    // only use it for swap account related tables, not membership related tables for instance.
    public function getdetails($tablename)
    {
        $query = $this->db->get($tablename);  
        $allrows = array();
        $i=0;
        foreach($query->result_array() as $row) 
        {
            $allrows[$i++]=$row;
        }
        return $allrows;       
    } 

    // returns all the games based on the query conditions.
    // @conditions - an associative array containing the conditions for the query.
    // returns an array with all the games based on the where clauses.
    public function gettargetswaps($where)  
    {      
        $query = $this->db->get_where('swaps',$where);
        $targetswaps = array(); 
        $i = 0; 
        foreach($query->result_array() as $s)  
        { 
            $query = $this->db->get_where('games',array('id'=>$s['gameid'])); 
            $details = $query->row_array();
            $gamedetails = array('name'=>$details['name'],'consoleid'=>$details['consoleid'],'genreid'=>$details['genreid'],'imgurl'=>$details['imgurl']);
            $targetswaps[$i] = array_merge($s,$gamedetails); 
            $i++;  
        } 
        return $targetswaps;
    }
}   
?>

基本上是继承人是我加载上述模型时得到的错误：

A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/phpgod/public_html/johnnyarias/ci_website/application/models/generalfeaturesmodel.php:50)
Filename: libraries/Session.php
Line Number: 672

这里是Session.php文件中抛出/或与错误有关的函数：

function _set_cookie($cookie_data = NULL)
{
    if (is_null($cookie_data))
    {
        $cookie_data = $this->userdata;
    }

    // Serialize the userdata for the cookie
    $cookie_data = $this->_serialize($cookie_data);

    if ($this->sess_encrypt_cookie == TRUE)
    {
        $cookie_data = $this->CI->encrypt->encode($cookie_data);
    }
    else
    {
        // if encryption is not used, we provide an md5 hash to prevent userside tampering
        $cookie_data = $cookie_data.md5($cookie_data.$this->encryption_key);
    }

    $expire = ($this->sess_expire_on_close === TRUE) ? 0 : $this->sess_expiration + time();

    // Set the cookie
    setcookie(
                $this->sess_cookie_name,
                $cookie_data,
                $expire,
                $this->cookie_path,
                $this->cookie_domain,
                $this->cookie_secure
            );
}

GeneralFeaturesmodel中的第50行是文件的结尾（紧跟在'？＆gt;'php标签之后）......我不知道这里会出现什么问题???

Answer 1

似乎也是你的＆lt;？php前面的标签空间，正如Damien所提到的那样，离开结束会更安全吗？＆gt;因此，如果在文件末尾保存换行符，则没有输出

codeigniter：为什么这个模型发出codeigniter会话相关的严重警告问题？
