Question

我正在尝试将数据库导出为CSV文件。 PHPmyadmin显示表只有大约25 MB。我尝试将全表导出分解为每次运行25000行。（总计约为60k）。不确定导致问题的原因。显然fetch_assoc导致了这种情况，但不确定原因。

 if( count($this->input->post()) > 0 ){


        $file = fopen("tmp/export.csv","w");
        $query = "SELECT * FROM  `data` WHERE export=0 LIMIT 2500";
        $result = $this->db->query($query);
        $row = $result->first_row('array');

        //prepare the titles
        $title =array();
        $firstrow = array();
        foreach ($row as $key => $value){
            $title[] = $key;
            $firstrow[] = $value;
        }
        //Write heading titles to the csv
        fputcsv($file,$title);
        fputcsv($file,$firstrow);
        while($row = $result->next_row('array')){
            $buffer = array();
            foreach ($row as $items){
            $buffer[]=$items;
            }
            fputcsv($file,$buffer);
        }

        fclose($file);

这是我得到的错误。 91个字节？

Fatal error: Out of memory (allocated 264503296) (tried to allocate 91 bytes) in /var/www/html/system/database/drivers/mysqli/mysqli_result.php on line 168

任何投入的人？
