从PHP的CSV导出中删除空行 [英] Remove empty lines from CSV Export in PHP
本文介绍了从PHP的CSV导出中删除空行的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用我在stackoverflow上找到的此功能
I am using this Function I found here on stackoverflow
function array_to_csv_download($array, $filename = "export.csv", $delimiter=";") {
$f = fopen('php://output', 'w');
foreach ($array as $line) {
fputcsv($f, $line, $delimiter);
}
header('Content-Type: application/csv');
header('Content-Disposition: attachement; filename="'.$filename.'";');
}
问题出在导出文件中,我现在有4个额外的空行.
The Problem is in the export file i have now 4 extra empty lines.
我如何解决此功能以防止出现这些多余的行.
How i can fix this function to prevent these extra lines.
Array (
[0] => Array ( [start] => 001-F15:B2:1-F [dest] => 002-F15:B2:5-Y [rres_1] => 100 [rres_2] => 100 [rres_3] => 100 [runit_1] => 0 [runit_2] => 0 [runit_3] => 0 [runit_4] => 0 [runit_5] => 0 [runit_6] => 0 [worker] => 0 [duration] => 12 )
[1] => Array ( [start] => 001-F15:B2:1-F [dest] => 005-F15:A5:3-M [rres_1] => 0 [rres_2] => 0 [rres_3] => 0 [runit_1] => 100 [runit_2] => 100 [runit_3] => 100 [runit_4] => 0 [runit_5] => 0 [runit_6] => 0 [worker] => 0 [duration] => 12 )
[2] => Array ( [start] => 006-F15:E4:2-Y [dest] => 004-F15:A5:1-Y [rres_1] => 0 [rres_2] => 0 [rres_3] => 0 [runit_1] => 0 [runit_2] => 0 [runit_3] => 0 [runit_4] => 100 [runit_5] => 100 [runit_6] => 100 [worker] => 100 [duration] => 12 )
)
此行已正确打印在export.csv
中
现在完整的代码:
function array_to_csv_download($array, $filename = "export.csv", $delimiter=";") {
header('Content-Type: application/csv');
header('Content-Disposition: attachement; filename="'.$filename.'";');
// open the "output" stream
// see http://www.php.net/manual/en/wrappers.php.php#refsect2-wrappers.php-unknown-unknown-unknown-descriptioq
$f = fopen('php://output', 'w');
foreach ($array as $line) {
fputcsv($f, $line, $delimiter);
}
}
$sql='SELECT p1.planet_name AS start, p2.planet_name AS dest, rres_1, rres_2, rres_3, runit_1, runit_2, runit_3, runit_4, runit_5, runit_6, worker, duration FROM traderoute tr
INNER JOIN planets p1 ON p1.planet_id=tr.start_planet
INNER JOIN planets p2 ON p2.planet_id=tr.dest_planet
WHERE player_id='.$game->player['user_id'];
$export=$db->queryrowset($sql);
array_to_csv_download($export);
die();
推荐答案
我需要在包含的PHP文件中的关闭PHP ?>
标记后清除行.然后,csv文件中的空行消失了.
I needed to clean the lines after the closing PHP ?>
tag in the included PHP files. Then the empty lines in the csv file were gone.
