ffputcsv() expects parameter 2 to be array,

[cal]

I have a form and I want to write the contents to a CSV file.

$fp is the file to write to.
$v are the values in the array $_POST.

foreach ($_POST as $i=>$v){
fputcsv($fp, $v);
}

I get this error message:
Warning: fputcsv() expects parameter 2 to be array, string given in .....

I think this must be very basic but I have not found any resource on the web identical to my question. Lots on arrays but not this particular question. The manual on fputcsv went into more complicated matters.

I can print out the array $_POST so I know there are values there.

I would appreciate any help you may give.

$_POST is an array but $v is a single value

you may just want:

fputcsv($fp, $_POST);

but i don't know what's in the post array that you want.

If you want one $_POST value per line, instead, then you could do:

fputcsv($fp, array($v));

But it all depends on what you actually want to do.

Thanks for this code. I will keep it in mind for another situation.

Today I am trying to write to one line so the
fputcsv ($fp, $_POST);
is what I need.

Thanks for your help, dagon.

This works for my project: I am taking the Post array from a form and writing it all in one line to a CSV file.
