从MySQL数据库导出数据到PHP中的excel
我是PHP新手。 我只是想导出数据（我从查询数据库中得到的search结果）为excel。 我的问题是在Excel中的数据会自动改变一个新的行。 我想要'cn''ai'…在下一列，但不是下一行。
我已经删除了所有$csv_output .= "\r"; 在我的代码。 所以我可能会有一些错误的查询语句：
$searchp = " select * from insecticide a LEFT JOIN crop b ON a.ID = b.ID where a.Pestcide_trade_name like'%$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！

不要自己编写CSV代码。 请参阅： http : //php.net/manual/en/function.fputcsv.php
此外，你缺less分隔符…但不要修复这个代码。 重构它。
你忘了逗号和引号：
$csv_output .= '"' . $tn1 . '",'; $csv_output .= '"' . $cn1 . '",'; // etc.
