我正在使用php类将数据写入CSV。课程链接：

类别代码：

<?php

class CSV_Writer {  

    public $data = array();  
    public $deliminator;  

    /** 
     * Loads data and optionally a deliminator. Data is assumed to be an array 
     * of associative arrays. 
     * 
     * @param array $data 
     * @param string $deliminator 
     */  
    function __construct($data, $deliminator = ",")  
    {  
        if (!is_array($data))  
        {  
            throw new Exception('CSV_Writer only accepts data as arrays');  
        }  

        $this->data = $data;  
        $this->deliminator = $deliminator;  
    }  

    private function wrap_with_quotes($data)  
    {  
        $data = preg_replace('/"(.+)"/', '""$1""', $data);  
        return sprintf('"%s"', $data);  
    }  

    /** 
     * Echos the escaped CSV file with chosen delimeter 
     * 
     * @return void 
     */  
    public function output()  
    {  
        foreach ($this->data as $row)  
        {  
            $quoted_data = array_map(array('CSV_Writer', 'wrap_with_quotes'), $row);  
            echo sprintf("%s\n", implode($this->deliminator, $quoted_data));  
        }  
    }  

    /** 
     * Sets proper Content-Type header and attachment for the CSV outpu 
     * 
     * @param string $name 
     * @return void 
     */  
    public function headers($name)  
    {  
        header('Content-Type: application/csv');  
        header("Content-disposition: attachment; filename={$name}.csv");  
    }  
}  
?>

问题是生成的文件。我有一个CSV文件而不是数组，只是HTML内容页。为什么会这样

CSV文件的内容：

Thx请求帮助。

您有两个问题：

您正在重新发明轮子，PHP已经做到了这一点。不要那样做

据我所见，您没有停止执行脚本，因此PHP将继续执行并呈现HTML文档的其余部分。我不能确切地告诉你为什么你没有看到前面有CSV信息的HTML，但也许输出缓存正在被刷新。解决方法是添加一个

exit（）该块末尾的行：


我不想打断你，但php内置了对编写csv文件的支持。。。这（几乎）完全不需要这个类。如果仍要将功能包装在类中以输出标题，请至少包装fputcsv，并且不要复制其功能。请参阅。或者至少悬停链接。你需要给我们更多的代码。您提供给我们的处理CSV创建的代码片段是完全正常和正常的。很有可能是其他东西在生成HTML并在CSV发出之前发出它。
