您可以为数组使用内置的fputcsv()从数组生成正确的 csv 行,因此您必须循环并收集这些行,如下所示:
$f = fopen("tmp.csv", "w");
foreach ($array as $line) {
fputcsv($f, $line);
}
要使浏览器提供“另存为”对话框,您必须发送这样的 HTTP 标头(请参阅rfc中有关此标头的更多信息):
header('Content-Disposition: attachment; filename="filename.csv";');
把它们放在一起:
function array_to_csv_download($array, $filename = "export.csv", $delimiter=";") {
// open raw memory as file so no temp files needed, you might run out of memory though
$f = fopen('php://memory', 'w');
// loop over the input array
foreach ($array as $line) {
// generate csv lines from the inner arrays
fputcsv($f, $line, $delimiter);
}
// reset the file pointer to the start of the file
fseek($f, 0);
// tell the browser it's going to be a csv file
header('Content-Type: text/csv');
// tell the browser we want to save it instead of displaying it
header('Content-Disposition: attachment; filename="'.$filename.'";');
// make php send the generated csv lines to the browser
fpassthru($f);
}
你可以像这样使用它:
array_to_csv_download(array(
array(1,2,3,4), // this array is going to be the first row
array(1,2,3,4)), // this array is going to be the second row
"numbers.csv"
);
更新:您还可以使用文件描述符
代替搜索并取消搜索等:php://memory
php://output
function array_to_csv_download($array, $filename = "export.csv", $delimiter=";") {
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="'.$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);
}
}
