Convert a utf-8 string to a utf-16 string in PHP

by Unknown in php 0

- You could also use iconv.
It's native in PHP, but require that all your text is one charset. Else it could discard characters.
iconv("UTF-8", "UTF-16", $text)

- In other way, mbstring supports UTF-16, so you can use mb_convert_encoding.

Localize Your Android Apps (Default files and folders)

by Unknown in Tutorial 0

Thinking about localizing your android app, well it is without a doubt a great way to popularize your app. Localization is one of the fastest growing trends in the app world today.
Localization is a process to provide resources for your app in accordance with the language setting of the device. The need to provide support of local language on the app is due to the fact that most users prefer reading and communicating in their local language.
Before you jump into this localizing wagon make sure what you want from your app. You want to target only the local audience or global audience as well?
Localizing your app is only beneficial if you’re targeting different regions with variety of languages. In order to appeal to more-and-more users, your app should support texts, currency, audio files, numbers, and graphics according to the locales.
If you want to make your android app global, you need to support local languages. For this you require resource files that are placed in the subdirectories of “res” folder. An additional directory is created inside “res/” which enables you to use a resource in a particular locale. Inside this directory, include a hyphen along with an ‘ISO 639-1 language codes’ at the end of the directory name. After this you can add two optional letters ‘ISO 3166-1-alpha-2 region code’ (preceded by ‘r’).
The inclusion of region qualifier helps in hitting the target resource more effectively. For instance, use ‘-es-rES’ for Espana (Spanish spoken in Spain) and ‘-es-rUS’ for Estados Unidos (Spanish spoken in Latin America), instead of ‘-es’ the language qualifier for Spanish.
Now, when the user runs the app and the device’s language matches the language you have specified, the language resources are loaded.

Writer SEO hints

by Unknown in SEO 0

Often you would have observed that some sentences in the articles or blogs are not perfect. This leads to the question that is sacrificing perfect sentence structure the way to find your space in the writing field?
In the lure to write more creative article or blog that appeals to the target audience, an audience that might not have good control over the English language, writers sometimes have to write less-than-perfect but easily understandable content.
This makes the work of editors that more difficult. Writers should not misuse this privilege and imagine no one will notice. In this article, we will take a look at a few common mistakes committed by writers, and how they can avoid committing them.

How to style the first occurrence of an element inside of another element?

by Unknown in css , jquery 0

Here's my problem.

HTML

<div id="content">
    <h1>Headline</h1>
    <p>First paragraph that needs to be yellow.</p>
    <p>Second paragraph that need not change. :) </p>
    <p>Third paragraph that need not change. :) </p>
</div>

If I use #content p:first-child {color:yellow; } it doesn't work because p isn't the first-child of content... h1 is the first born.

How can I do this without touching the HTML code?

PDO query to fetch all tables

by Unknown in mysql , php 0

Execute the query with PDO::query():

SHOW TABLES;

If you fetch an associative array, the name of the column will be:

Tables_in_databasename

Note: this will list both tables and views. If you must get only tables, use this instead:

SELECT 
  TABLE_NAME
FROM information_schema.TABLES 
WHERE
  TABLE_TYPE='BASE TABLE'
  AND TABLE_SCHEMA='yourdatabasename';

Htaccess show no_found picture if picture is not exist

by Unknown in htaccess , php 0

RewriteEngine On
RewriteCond %{REQUEST_URI} \.(jpg|jpeg|gif|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .*$ /no_picture.png [L]

Let's break it down as to what each line means.

RewriteCond %{REQUEST_URI} \.(jpg|jpeg|gif|png)$ [NC]

Check to see if the requested file is of a file extension in the parentheses (). In this case, we're testing to see if the file name ends in either .jpg, .jpeg, .gif or .png

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Check that the file is not there and it's also not a directory.

RewriteRule .*$ /no_picture.png [L]

If a requested resource/file passes all those tests, then it's an image that does not exist. So serve back the image of no_picture.png to the browser. This will keep the filename. If you want to redirect to the no_picture.png filename, change [L] to [R]

JavaScript QR Code Reader

by Unknown in html5 , javascript 0

I'm doing a bit of preliminary research on an upcoming project and I have a quick question that I figure I'll throw up here while I look elsewhere, in case anyone has any experience with this.

The question is simple: is it possible to read a QR code using JavaScript? Is there a remote service to which I can pass a bitmap object from a camera and do it that way? Are there currently any libraries that allow this?

The project is going to be deployed to various mobile devices and we'd like to try to use Appcelerator to make it work. I know Appcelerator does expose the Camera API on its host devices, but whatever we do with it has to be able to parse QR codes. Is this something that can be done?

Thanks in advance!
