内容类型：text / csv将html输出到csv文件中

Question

I can't seem to output only specific information, into a csv or any file. The following, eg, output the html from the page, rather than the data that I'm trying to send to the Applicants.csv:

(the $a_Lines array has already been populated):

header('Content-type: text/csv');
header('Content-Disposition: attachment; filename="Applicants.csv"');
header('Pragma: no-cache');
header('Expires: 0');

$file = fopen('php://output', 'w');

foreach ( $a_Lines as $row ) {
    fputcsv($file, $row);
}
fclose($file);

Answer 1

Make sure that in expression

fputcsv($file, $row);

$row is always array. If you want to create from $a_Lines csv file, then you don't need foreach loop (of course, I presume that $a_Lines is array). In case that you want selected data from $a_Lines array, then run through $a_Lines, create new array or transform existing one and after the loop add prepared array into fputcsv function.
