Issue on opening, editing and downloading a .csv file on PHP - php

Question

I want to open a csv file named csv.csv with PHP, then add new rows in this file, and finally download the news csv.
The content of csc.csv is:
name, town
name1, town1
name2, town2
name3, town3
name4, town4
and I want to add these rows:
name5, town5
name6, town6
I made this PHP code but it doesn't work:
<?php
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
$file = fopen("csv.csv","r");
$list = array();
while(! feof($file))
{
$list[] = array(print_r(fgetcsv($file)));
}
fclose($file);
$list[] = array('name5', 'town5');
$list[] = array('name6', 'town6');
outputCSV($list);
function outputCSV($list) {
$output = fopen("php://output", "w");
foreach ($list as $row) {
fputcsv($output, $row);
}
fclose($output);
}
?>

Answer 1

Here is your working code.
<?php
$file = fopen("csv.csv","a+");
$list = array();
$list[] = array('name5', 'town5');
$list[] = array('name6', 'town6');
foreach ($list as $fields) {
fputcsv($file, $fields,',');
}
fclose($file);
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=csv_".time().".csv");
header("Pragma: no-cache");
header("Expires: 0");
?>
UPDATE 1 :
for creating new file without editing existing one.
<?php
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
$file = fopen("csv.csv","r");
$list = array();
while(! feof($file))
{
$list[] = (fgetcsv($file));
}
fclose($file);
$list[] = array('name5', 'town5');
$list[] = array('name6', 'town6');
$list = array_filter($list);
outputCSV($list);
function outputCSV($list) {
$output = fopen("php://output", "w");
foreach ($list as $row) {
fputcsv($output, $row);
}
fclose($output);
}
?>
