将php导出为ex​​cel时出现资源ID＃7错误

Question

将PHP数组导出到Excel文档。我在文档的最后部分收到错误Resource id #7。 PHP数组是

(       
    [0] => Array        
        (       
            [0] => Reg      
            [1] => Fname        
            [2] => Lname        
        )       

    [1] => Array        
        (       
            [0] => 63       
            [1] => Praveen      
            [2] => s        
        )       

    [2] => Array        
        (       
            [0] => 57       
            [1] => Prasad       
            [2] => K        
        )       

    [3] => Array        
        (       
            [0] => 456      
            [1] => Prabharan        
            [2] => G        
        )       

    [4] => Array        
        (       
            [0] => 080105306062     
            [1] => prasad       
            [2] => kppp     
        )       

)

并且excel文档中的输出是

Reg Fname   Lname
63  Praveen s
57  Prasad  K
456 Prabharan   G
80105306062 prasad  kppp
Resource id #7      

php代码是：

 $fp = fopen('php://output', 'w');
            foreach ($list1 as $fields)
            {
                fputcsv($fp, $fields);
            }
            header('Content-Description: File Transfer');
            header('Content-Type: application/octet-stream'); 
            header('Content-Disposition: attachment; filename=export.csv');
            header('Content-Transfer-Encoding: binary');
            header('Content-length:'.count($list1));
            header('Expires: 0');
            header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
            header('Pragma: public');
            fclose($fp);
            die($fp);

Answer 1

尝试使用 ob_start（）和 ob_get_clean（）

ob_start();

$fp = fopen('php://output', 'w');

//Your code to create CSV content
foreach ($list1 as $fields)
{
    fputcsv($fp, $fields);
}
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=export.csv');
header('Content-Transfer-Encoding: binary');
header('Content-length:'.count($list1));
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
fclose($fp);

//After file is created, make it output
die(ob_get_clean());
