最近做了一个项目需要把订单的信息显示出来，并且能够把相关信息放到一个.csv 文件中，下载到浏览器。首先我要说明的是.csv 文件，PHP 有专门的函数去解析该类型的文件，相关函数大家可以去官网查看。注意.csv 文件内容的编码格式是gbk格式的，所以有必要对字符格式进行转码。文件的样式如下。
一、首先要定义header 头
// 输出Excel文件头，可把user.csv换成你要的文件名 header ( 'Content-Type: application/vnd.ms-excel' ); header ( 'Content-Disposition: attachment;filename="订单数据.csv"' ); header ( 'Cache-Control: max-age=0' ); // 打开PHP文件句柄，php://output 表示直接输出到浏览器 $fp = fopen ( 'php://output', 'a' ); // 输出Excel列名信息
二 、下面是文件的头部
$head = array ('订单号','','订单名称','','业务ID','','渠道ID','','渠道类型','','产品线名称','','原始订单号','','订单金额',
'','From值','','订单时间','','收款合同号','','渠道名称','','付款合同号','','供应商名称','','运营平台','','产品类型',
'','记账时间','','渠道成本比例','','渠道成本','','应收账款','','结算比例','','应付结算','','是否已回款','','是否已提批次',
'','备注');
foreach ( $head as $i => $v ) {
// CSV的Excel支持GBK编码，一定要转换，否则乱码
$head [$i] = iconv ( 'utf-8', 'gbk', $v );
}
// 将数据通过fputcsv写到文件句柄
fputcsv ( $fp, $head );
三、下面是文件的内容，以我的例子是从数据库读出来的，看不懂没关系，原理是把结果查出来放到数组中，循环数组，把每个结果放到一个新的数组并且进行编码。忘了告诉你我用的是CI（codeignite）框架
if ($this->input->get () != false) {
// 从数据库中获取数据，为了节省内存，不要把数据一次性读到内存，从句柄中一行一行读即可
$sql = "select Charge_final.charge_id,
Charge_final.product_name,
Charge_final.business_id,

where 1=1 $conditions order by Charge_final.charge_time desc";
$query = $this->db->query ( $sql );
// 计数器
$cnt = 0;
// 每隔$limit行，刷新一下输出buffer，不要太大，也不要太小
$limit = 8000;
foreach ( $query->result_array () as $row ) {
$cnt ++;
if ($limit == $cnt) { // 刷新一下输出buffer，防止由于数据过多造成问题
ob_flush ();
flush ();
$cnt = 0;
}
$income_id=$row['income_id']==0?'未回款':'回款';
$payment_id=$row['payment_id']==0?'未提':'已提';
// 读取表数据
$content = array ();
$content [] = iconv ( 'utf-8', 'gbk', $row ['charge_id'] . "\t" );
$content [] = '';
$content [] = iconv ( 'utf-8', 'gbk', $row ['product_name'] );
$content [] = '';

$content [] = '';

fputcsv ( $fp, $content );
}
三、文件的尾部
$sql="select sum(Charge_final.fee) as amountorder,
sum(Charge_final.channel_fee) as sumchannel_fee,
sum(Charge_final.fee-Charge_final.channel_fee) as sumaccout,
sum(Charge_final.payment_fee) as sumpayfee
from {$this->Charge_final} as Charge_final
left join {$this->bass_productline} as bass_productline on
Charge_final.channel_id=bass_productline.channel_id and
Charge_final.channel_type=bass_productline.channel_type
where 1=1 $conditions";
$querys = $this->db->query ( $sql );
$ro = $querys->result_array ();
$this->data ['ro'] = $ro;
$amountorder=$ro['0']['amountorder'];
$sumchannel_fee=$ro['0']['sumchannel_fee'];
$sumaccout=$ro['0']['sumaccout'];
$sumpayfee=$ro['0']['sumpayfee'];
$foot = array ('统计','','','','','','','','','','','','','',"$amountorder",
'','','','','','','','','','','','','','','','',
'','','','','',"$sumchannel_fee",'',"$sumaccout",'','','',"$sumpayfee",'','','','',
'','');
foreach ($foot as $i => $v ) {
// CSV的Excel支持GBK编码，一定要转换，否则乱码
$foot[$i] = iconv ( 'utf-8', 'gbk', $v );
}
// 将数据通过fputcsv写到文件句柄
fputcsv ( $fp, $foot);
}
}
}
PHP 生成.csv 文件并下载到浏览器
