# Online Visitors Counter

[![License](https://badgen.net/badge/license/MIT/blue)](http://victor.mit-license.org/)

Real-time online visitors counter using Ajax, PHP PDO and SQLite.

It adds a discrete link (auto-refreshed every 15 seconds) with the number of current users on the website.

If the link is clicked, a list of pages currently been visited appears, along with the number of visitors in each page.

## Requirements

- PHP5 (or later) with PDO SQLite extension
- SQLite
- Write permission on the folder 'ovc' so php can create and use the sqlite database

If you're not using a webhosting panel, like cPanel or VestaCP, please, install the above requirements manually on your OS.

## Usage

Download and unzip [this package](https://github.com/felladrin/online-visitors-counter/archive/master.zip).

Then upload the folder `ovc` to your website (anywhere).

Now you just need to call it:

```html
<script src="path/to/ovc/counter.js"></script>
```

## Example

The `index.html` of this package is the best example you can find. You'll understand when you run it. (Remember it needs to be run on a PHP server).

But here is another quick example: Let's say your website is `http://example.com` and you've uploaded the `ovc` folder to the root directory, you would call the script like this:

```html
<script src="http://example.com/ovc/counter.js"></script>
```

## Customizing

On the config.php file, you'll find a lot of customizable parameters. Easy to set, as you can see on the following example.

If you want the link to show "X Online", you'd set:

```php
$visitorSingular = "Online";
$visitorPlural = "Online";
$linkFormat = '%1$d %2$s';
```

And the result would be:
