如何使用php将mysql数据表搜索查询导出为csv？

听到的是查询

if ($_REQUEST["startfrom"]<>'' and $_REQUEST["end"]<>'') {
    $sql = "SELECT ECRNo,SalesDate,TimeSold,AmountDue,OutletName,ProductCode,Category,MealType,SUM(Quantity) AS Quantity1,SUM(NetPrice) AS NetPrice1 FROM ".$SETTINGS["data_table"]." WHERE SalesDate BETWEEN '".mysql_real_escape_string($_REQUEST["startfrom"])."'And'".mysql_real_escape_string($_REQUEST["end"])."'".$search_OutletName.$search_Category.$search_ProductCode.$search_groupby;
} else if ($_REQUEST["startfrom"]<>'') {
    $sql = "SELECT ECRNo,SalesDate,TimeSold,AmountDue,SalesDate,OutletName,ProductCode,Category,MealType,SUM(Quantity) AS Quantity1,SUM(NetPrice) AS NetPrice1 FROM ".$SETTINGS["data_table"]." WHERE SalesDate >= '".mysql_real_escape_string($_REQUEST["startfrom"])."'".$search_OutletName.$search_Category.$search_ProductCode.$search_groupby;
} else if ($_REQUEST["end"]<>'') {
    $sql = "SELECT ECRNo,SalesDate,TimeSold,SalesDate,AmountDue,OutletName,ProductCode,Category,MealType,SUM(Quantity) AS Quantity1,SUM(NetPrice) AS NetPrice1 FROM ".$SETTINGS["data_table"]." WHERE SalesDate <= '".mysql_real_escape_string($_REQUEST["end"])."'".$search_OutletName.$search_Category.$search_ProductCode.$search_groupby;
}else {
    $sql = "SELECT ECRNo,SalesDate,TimeSold,SalesDate,AmountDue,OutletName,ProductCode,Category,MealType,SUM(Quantity) AS Quantity1,SUM(NetPrice) AS NetPrice1 FROM ".$SETTINGS["data_table"]." WHERE ECRNo>0 ".$search_OutletName.$search_Category.$search_ProductCode.$search_groupby;
}

如何导出查询结果？

Answer 1

所有好的答案都在这里，但如果您想使用 PHP 来完成，这里是另一种选择:

<?php

$list = array (
    array('aaa', 'bbb', 'ccc', 'dddd'),
    array('123', '456', '789'),
    array('"aaa"', '"bbb"')
);

$fp = fopen('file.csv', 'w');

foreach ($list as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
?>

$list 数组将是您从数据库中得到的结果。
