Nightbot Quotes Custom API

Nightbot custom api 101: In writing a custom api for Nightbot, you have to know about the limitations. The big limitation is that nightbot custom api can only handle raw text output on  a website. This means that everything needs to be processed server side and outputted as raw text. In this example, we have a PHP script read lines from "quotes.txt" and output a single line to the URL we feed nightbot custom api ("http:://HOST.com/nightbot/CHANNEL/quotes.php").

To add this api to your nightbot, add the command;
!addcom !quote !(customapi <URL>)

All the command does is output the raw text contents of the website to nightbot.
NB: Nightbot will not handle HTML, so if the text-output contains HTML code, nightbot will only output <html>

Disclaimer: This code is used as a Nightbot custom API to output a random quote from the text-file "quotes.txt".
The text-file MUST be formatted so that quotes are separated by lines

Ex. textfile(quotes.txt):
"Do NOT let the Viking near the redstone" - Everyone, 2015
"Keep you meat away from me!" - Jynx, 2015

"This code can handle an empty line in the text file as well!" - Wacky, when writing the pastebin!

<?php
        // This array stores all the quotes.
        $quotes = array();

    // Opens a file for reading
        $file = fopen("quotes.txt", "r");

    // Loops through file line for line
        while(! feof($file)){
        // Put current line into a temporary variable
                $str = fgets($file);
        // Check to see if the current line is empty
        if($str != "") {
            // If the line is not empty, add it to the quotes-array.
                    $quotes[] = $str;
        }
        }

    // Pick a random number(index) in the quotes-array
        $r = rand(0, count($quotes)-1);
    // Increment number of index, to make it human non-programmer understandable which quote we are seeing.
        $current = $r + 1;

    // Output raw text-data to the custom-api URL, with the quote, and a number(index + 1) so people know which quote(in
        // number) are being outputtet.
        echo 'Quote(' . $current . '):' . $quotes[$r];


    // Close the "quotes.txt" file stream. ALWAYS close the file stream. ALWAYS.
        fclose($file);
