    while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
        if(! ($i % 150) ) $file_index++;
$i++; 
        file_put_contents ( $file_index.'.txt' , $row[0].  PHP_EOL, FILE_APPEND );

    mysql_free_result($result);
    }
else
{
 die('连接失败');
}

?>


------解决方案--------------------
PHP code

//先定义好 $prefix, $suffix的值,说白了就是字符串连接问题。。你能写这些代码,字符串连接不会?

file_put_contents ( $file_index.'.txt' , $prefix . $row[0] . $suffix . PHP_EOL, FILE_APPEND ); <div class="clear">
                 
              
              
        
            </div>
