如何使用PHP导出.dat或.txt格式的文件 [英] How to export file in .dat or .txt format using php

问题描述

我有功能export_csv()将文件导出为.csv格式.我想更改.dat或.txt格式，而不是.csv

I have function export_csv()to export file as .csv format. I want to change .dat or .txt format instead of .csv

当前代码:

public function export_csv() {
  
  if( ! $this->path) { throw new exception('unable to create xls: missing path'); }
       /** output conetnts to csv **/
       ob_start();
       $df = fopen($this->path.'.csv', 'w');
       foreach ($this->data as $row) {
       fputcsv($df, $row);
       }
      fclose($df);
      return $this->path;
}

我尝试了下面的代码.但是.dat文件为空.文件大小0

I have tried below code. but .dat file was blank. The file size 0

public function export_dat() {
    
    if( ! $this->path) { throw new exception('unable to create xls: missing path'); }
    /** output contents to dat **/
        ob_start();
        $df = fopen($this->path.'.dat', 'w');
        foreach ($this->data as $row) {
            fwrite($df, $row);
        }
         fclose($df);
         
         return $this->path;
}

感谢您的帮助.

推荐答案

fwrite采用字符串，而不是数组.尝试这样的事情:

fwrite takes a string, not an array. Try something like this:

fwrite($df, implode(', ', $row));
