Question

我是PHP的新手。我只想将数据（我从查询数据库中获得的搜索结果）导出到excel。我的问题是excel中的数据会自动更改新行。 我想要'cn''ai'...在下一栏但不是下一行。

我已经删除了代码中的所有$csv_output .= "\r";。所以我的查询语句可能有问题：

$searchp = "
    select 
        * 
    from 
        insecticide a 
            LEFT JOIN crop b 
                ON a.ID = b.ID 
    where 
        a.Pestcide_trade_name like'%$tn%' 
        and a.Pestcide_trade_name like'%$tn2%' 
        and b.Crops like'%$crops%' 
        and b.Crops like'%$crops2%' 
        and a.AMW like'%$amw%' 
        and b.Pests like'%$pest%' 
        and a.Company_name like'%$cn%' 
        and a.Company_name like'%$cn2%' 
        and a.Active_ingredient like'%$ai%' 
        and a.Active_ingredient like'%$ai2%' 
        and a.PPE like'%$ppe%' 
        and a.PPE like'%$ppe2%' 
        and a.MMW like'%$mmw%' 
        and a.EH like'%$eh%' 
        and b.REI like'%$rei%' 
        and b.REI like'%$rei2%' 
    ORDER BY 
        a.Pestcide_trade_name ASC"

我是PHP和MySQL的新手。请给我一些关于这个问题的提示。谢谢！

Answer 1

请勿自行编写CSV代码。请参阅：http://php.net/manual/en/function.fputcsv.php

此外，您缺少分隔符...但不修复此代码。重构它。

Answer 2

你忘记了逗号和引号：

        $csv_output .= '"' . $tn1 . '",';
        $csv_output .= '"' . $cn1 . '",';
        // etc.
