How To write one column array to csv file

[johanvena]

I am trying to write post variables to a csv file but it writes everything in one line separated by comma

<?php

$list= array($_POST['purchases']);
$file = fopen("purchases.csv", "w");

foreach ($list as $line)
{
fputcsv($file, $line); 
}

fclose($file); 
?>

Result in purchases.csv file

Marilyn,Nancy,Johan,Carol,Juanic,Shirley

But I want every string value on separated line

Marilyn
Nancy
Johan
Carol
Juanic
Shirley

try

foreach ($_POST['purchases'] as $line)
{
    fputcsv($file, $line); 
}

Thanx for reply. Tried it but gives error

Warning: fputcsv() expects parameter 2 to be array, string given in /home1/mymobi/public_html/mybank/update.php on line 7

My Code

<?php

$file = fopen("purchases.csv", "w");

foreach ($_POST['purchases'] as $line)
{
    fputcsv($file, $line); 
}

fclose($file); 
?>

foreach ($_POST['purchases'] as $line)
{
    fputcsv($file, [$line]); 
}
