It’s really amazing how Google is providing cool APIs for every this and that! And here comes another one that impressed me 😀 I am talking about the Text To Speech API by Google. It’s fantastic! I wrote a php wrapper class that would help you create mp3 files from texts 🙂 Of course, using Google as the medium!

Here’s the source code:

<?php
// FileName: tts.php
/*
 *  A PHP Class that converts Text into Speech using Google's Text to Speech API
 *
 * Author:
 * Abu Ashraf Masnun
 * https://masnun.com
 *
 */

class TextToSpeech {
    public $mp3data;
    function __construct($text="") {
        $text = trim($text);
        if(!empty($text)) {
            $text = urlencode($text);
            $this->mp3data = file_get_contents("http://translate.google.com/translate_tts?q={$text}");
        }
    }

    function setText($text) {
        $text = trim($text);
        if(!empty($text)) {
            $text = urlencode($text);
            $this->mp3data = file_get_contents("http://translate.google.com/translate_tts?q={$text}");
            return $mp3data;
        } else { return false; }
    }

    function saveToFile($filename) {
        $filename = trim($filename);
        if(!empty($filename)) {
            return file_put_contents($filename,$this->mp3data);
        } else { return false; }
    }

}
?>

<?php

// FileName: tts.php

class TextToSpeech {

public $mp3data;

function __construct($text="") {

$text = trim($text);

if(!empty($text)) {

$text = urlencode($text);

$this->mp3data = file_get_contents("http://translate.google.com/translate_tts?q={$text}");

}

function setText($text) {

$text = trim($text);

if(!empty($text)) {

$text = urlencode($text);

$this->mp3data = file_get_contents("http://translate.google.com/translate_tts?q={$text}");

return $mp3data;

} else { return false; }

}

function saveToFile($filename) {

$filename = trim($filename);

if(!empty($filename)) {

return file_put_contents($filename,$this->mp3data);

} else { return false; }

}

And here’s demo :

<?php
require "tts.php";
$tts = new TextToSpeech();
$tts->setText("Hello World!");
$tts->saveToFile("masnun.mp3");
?>

<?php

require "tts.php";

$tts = new TextToSpeech();

$tts->setText("Hello World!");

$tts->saveToFile("masnun.mp3");

You can alternatively pass the text to the constructor of the object like this:

<?php
require "tts.php";
$tts = new TextToSpeech("Hello World!");
$tts->saveToFile("masnun.mp3");
?>

<?php

require "tts.php";

$tts = new TextToSpeech("Hello World!");

$tts->saveToFile("masnun.mp3");

That is simple, isn’t that? Hope you like it!

FeedParser: A PHP Class for Quick Feed Parsing

1 Comment on FeedParser: A PHP Class for Quick Feed Parsing

Well, it doesn’t require any further explanation — we the web developers know how often we need to parse feeds. It’s a very common practice to use SimpleXML for parsing feeds. But today Hasin vai (Hasin Hayder) showed me a very cool thing — the Google Feed Parser. It’s a web based feed parser that is internally used by Google. The coolest thing about the parser is that it returns data as JSON 🙂

Seeing the point, I quickly fired off my netbeans IDE and wrote a php class for quick feed parsing 😀 Why fetch the feed and then parse it? Let Google handle the parsing and fetch the parsed results 🙂 Google is really making our lives simpler!

Here’s the class definition:

<?php
// Filename: feedparser.php
class FeedParser {
    function parse($feedUrl="https://masnun.com/feed/rss/",$number=5) {
        $feedUrl = urlencode($feedUrl);
        $gUrl = "http://www.google.com/uds/Gfeeds?num={$number}&hl=en&output=json&q={$feedUrl}&v=1.0";
        $json = json_decode(file_get_contents($gUrl),true);
        return  $json["responseData"]["feed"];
    }
}
?>

<?php

// Filename: feedparser.php

class FeedParser {

function parse($feedUrl="https://masnun.com/feed/rss/",$number=5) {

$feedUrl = urlencode($feedUrl);

$gUrl = "http://www.google.com/uds/Gfeeds?num={$number}&hl=en&output=json&q={$feedUrl}&v=1.0";

$json = json_decode(file_get_contents($gUrl),true);

return $json["responseData"]["feed"];

}

So, how do you use it? Initiate a new FeedParser object and then call the parse() method with the feed URL and entry count. The second parameter is optional and is “5” by default.

<?php
include("feedparser.php");
$parser = new FeedParser();
$data = $parser->parse("https://masnun.com/feed/rss/",3);
echo  $data["entries"][2]['title']."\n";
?>

<?php

include("feedparser.php");

$parser = new FeedParser();

$data = $parser->parse("https://masnun.com/feed/rss/",3);

echo $data["entries"][2]['title']."\n";

So what do we get in the $data array? Good question, lets see :

<?php
include("feedparser.php");
$parser = new FeedParser();
$data = $parser->parse("https://masnun.com/feed/rss/",3);
var_dump( $data );
?>

<?php

include("feedparser.php");

$parser = new FeedParser();

$data = $parser->parse("https://masnun.com/feed/rss/",3);

var_dump( $data );

JSDB: A JavaScript Interpreter

2 Comments on JSDB: A JavaScript Interpreter

Recently I have taken keen interest in JavaScript, mainly because to handle jQuery better. I have always found JS very cool but never had the time to dig deeper into the language. In this EID vacation at KU, I had plenty of leisure times even after my tasks at Leevio and the free lance jobs. I started passing time with JS and found something really cool that I didn’t know so far.

JavaScript is a programming language. Yeah, just like the interpreted languages like Python, PHP and Ruby, JS is another good old programming language. My ignorance, I never knew this! 🙁 I have always thought that JavaScript is merely a client side scripting language that works with web browsers only 😛

My perceptions started changing few months ago when I saw some server side applications of JavaScript coding. Lately, a few days back I saw the node.js projects which is quite similar to the Twisted project implemented in Python. I started wondering how JS is being interpreted on the server side. Google answered me 😀 There are JavaScript interpreters for even shell scripting 🙂

I first tried the interpreters from Mozilla but unfortunately couldn’t make them work on my machine. So, I switched to JSDB 😀 The interpreter is available free for download at: http://www.jsdb.org/ 🙂

They say on their homepage:

JSDB is JavaScript for databases, a scripting language for data-driven, network-centric programming on Windows, Mac, Linux, and SunOS. JSDB works with databases, XML, the web, and email. It is free and open-source. Use it as a JavaScript shell, to run CGI programs, or as a web server.

Yeah, I indeed use it as a JavaScript Shell 😀

Here is the Documentation of what JSDB has inside. I have made a PDF print out of the page for offline reading!

I really find the tool interesting because I am writing small throw away programs those are not really that much useful but the development curve is contributing to my JS skills 😀
