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。虽然说csv是一种比较简单的excel表格形式，生成只要按指定格式然后生成.csv文件就可以，但是在使用中也会遇到很多问题，下面给大家分享下PHP下载csv文件及问题总结
首先大家先看个例子，生成csv文件并下载
//要生成csv文件的数组
$csvArr=array();
$csvArr[]=array('用户编号1','上班日期1','签到时间1','签退时间1');
$csvArr[]=array('用户编号2','上班日期2','签到时间2','签退时间2')
download_send_headers("data_export_" . date("Y-m-d") . ".csv");
$head=array('用户编号','上班日期','签到时间','签退时间');
echo array2csv($csvArr,$head);
unset($csvArr);
die();
function array2csv(array &$array,$head)
{
if (count($array) == 0) {
return null;
}
ob_start();
$df = fopen("php://output", 'w');
if(!$head){
$head=array_keys(reset($array));
}
fputcsv($df,$head);
foreach ($array as $row) {
fputcsv($df, $row);
}
fclose($df);
return ob_get_clean();
}
function download_send_headers($filename) {
// disable caching
$now = gmdate("D, d M Y H:i:s");
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");
// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
// disposition / encoding on response body
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");
}
php array生成csv文件
<"example";
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename={$filename}.csv");
header("Pragma: no-cache");
header("Expires: 0");
outputCSV($data);
function outputCSV($data) {
$outputBuffer = fopen("php://output", 'w');
foreach($data as $val) {
foreach ($val as $key => $val2) {
$val[$key] = iconv('utf-8', 'gbk', $val2);
// CSV的Excel支持GBK编码，一定要转换，否则乱码
}
fputcsv($outputBuffer, $val);
}
fclose($outputBuffer);
}
"htmlcode">
function __fgetcsv(& $handle, $length = null, $d = ',', $e = '"') {
$d = preg_quote($d);
$e = preg_quote($e);
$_line = "";
$eof=false;
while ($eof != true) {
$_line .= (empty ($length) "htmlcode">
<"D, d M Y H:i:s");
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");
// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
// disposition / encoding on response body
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");
$items_data=array(
'0'=>array('title'=>'test test test1'),
'1'=>array('title'=>'test test test2'),
'2'=>array('title'=>'test test test3')
)
print(chr(0xEF).chr(0xBB).chr(0xBF));
//设置utf-8 + bom ，处理汉字显示的乱码
echo array2csv($items_data);
function array2csv(array &$array)
{
if (count($array) == 0) {
return null;
}
ob_start();
$df = fopen("php://output", 'w');
fputcsv($df, array_keys(reset($array)));
foreach ($array as $row) {
fputcsv($df, $row);
}
fclose($df);
return ob_get_clean();
}
"\t".
php 程序可以这样判断，注意一定是"\t"，不是'\t'.
复制代码 代码如下:
is_numeric($val)"\t":$val;
