Storing unicode texts in MySQL with phpMyAdmin

Today, I've received a personal mail/request from Sivanantham Hemamalini, working for IT leisure in Singapore. Since I was in company when received the mail, I couldn't answer immediately. If I understand the question right, it is about inputting Unicode texts especially Tamil in phpMyAdmin.

PhpMyAdmin's default characterset is iso-8859-1 and so if we enter anything in the form, browser will convert it into numerical html entities. Say for example, if we enter தமிழ் and submit the form, it will convert it to & #2980;& #2990;& #3007;& #2996;& #3021;. Because of this browser's behavior, it will be difficult to store the Unicode text as it is.


Immediate solution I could think of is changing or forcing the browser's character encoding into utf-8. In Mozilla Firefox, it can be set via View -> Character Encoding -> Unicode (UTF-8)

Another elegant solution might be changing the phpMyAdmin configurations so that it sends and sets proper charset in Content-Type header as Content-Type: text/html; charset=utf-8
To do this, we have to edit the file found at phpMyAdmin's root directory:
$cfg['DefaultCharset'] = 'utf-8'; and
$cfg['AllowAnywhereRecoding'] = true;
These change of configurations should send proper headers. Anyhow, if the lang cookie is already set to some other charset, it won't reflect the changes. So, one may need to clear the cookies to see the changes.

I edit the file to this,
$cfg['DefaultCharset'] = 'utf-8'; and
$cfg['AllowAnywhereRecoding'] = true;
But i am getting error stating "Can not load iconv
recode extension needed for charset conversion,
configure php to allow using these extensions or
disable charset conversion in phpMyAdmin."
what is the solution for this.
I am using windows XP and php,v
thanks in advance
Hema, as the error message says it couldn't load the iconv extension, as it is not enabled. You can enable and disable PHP extensions via php.ini configuration file.

Use phpinfo() function to find the path of php.ini file.
To enable the iconv extension, just uncomment the line ;extension=php_iconv.dll (that is just remove the leading semicolon ";") in php.ini
You may need to restart Apache for the changes to reflect. Again use phpinfo() to see if the module is enabled or not. Now, you're done.

This procedure applies to any PHP extensions on Windows.

Do you have to use phpMyAdmin? I would write a simple PHP script to accept the input correclty and post to the db. The other solutions sound like more work.

Using Sodexo Meal Pass Card in - How-to

How to Use Sodexo Meal Pass Card in Sodexo started to issue Smart Card similar to Credit Card--instead of their usual paper based vouchers.

I was using Sodexo vouchers for longtime, but it was a big letdown when I can't get some of my unused vouchers renewed. And so, I was somehow happy with their new Meal Pass Card. But, again, it was a big letdown as I can't use it with BigBasket--where I usually use most of my meal coupon vouchers.
SMS message from Sodexo on December 20, 2017 1:18 PM came as a big surprise, as I was waiting for this for longtime:
Great News! Pay with your Sodexo Meal Card for food items ordered from Big Basket. Choose Sodexo in the payment section & pay on delivery.

And so, this month, I tried to use my Sodexo Meal Pass Card in BigBasket.

BigBasket website had not much information; I thought that I have to swipe my Meal Pass Card. Delivery person also didn't have much information; initially he was rejecting my Card! I tried to contact …

Who is S.P. Udayakumar, (Koodankulam anti-nuclear) activist of the year

I greatly admired S.P. Udayakumar  (Koodankulam anti-nuclear activist) for his calm and composed response; it is usually not easy to reply moronic Narayanasamy and moronic Ponraj (advisor of Abdul Kalam) who're always blabbering irrationally. By wrongly judging from his sober and humble look, I'd thought that he's an illiterate villager from Koodankulam. But, recently I came to know that he's studied in USA and worked as a professor there. My respect for him greatly increased when I compared him with other exhibitionist NRIs.

Here are the details that I collected...

Name: S.P. Udayakumar

Native: Nagercoil

Converting PSD with PHP/ImageMagick

After seeing feature rich options in Imagick PECL extension at Mikko Koppanen's (the author) website and also impressed with ImageMagick's features, I have decided to use it for the PSD to XHTML conversion website that I'm architecting and managing.

Since, the team wants programming help for converting PSD images, I have tried it (documentation is sparse on PSD handling)

Converting PSD to PNG/JPEG/etc
Note that, flattenImages() is needed for layered/multi-page PSD file.

$im = new Imagick('test.psd');

Extracting PSD layers
One by one

$im = new Imagick('test.psd');
for ($i = 0, $num_layers = $im->getNumberImages(); $i < $num_layers; ++$i) {
$im->writeImage('layer' . $i . '.png');

Note that, there is a better version below
