Add a comma to the end of each line using php

Question

I have a csv file with 1 email id on each line. I want to add a comma after each email id. I want to add a comma to the end of each line using php. How can i do this? Is there a specific function for this?

UPDATE I want this so that I can build an array from it in javascript.

I will upload the csv file using php and then print it in js.

how

var myCars=[<?php print $csv; ?>]; 

So, I get something like this.

var myCars=["[e-mail]","[e-mail]","[e-mail]"];

Or is there a better way to do this?

Answer 1

Why not use csv special features?

$old = fopen('file.csv','r');
$new = fopen('new.csv','w+');
while($line = fgetcsv($old))
{
    fputcsv($new,$line);
}
fclose($old);
fclose($new);

csv, , javascript, :

$file = fopen ('file.csv','r');
$all = array();
while($line = fgetcsv($file))
{
    $all[] = $line[0];//if there is only 1 field/line
    $all = array_merge($all,$line);//if multiple
}
fclose($file);
$js_array = '["'.implode('",',$all).'"];';
//or, the way I'd advise against, but good for multi-dimensional, assoc arrays
echo 'var array = JSON.parse("'.json_encode($all).'");';
