First of all I will congratulate you on upgrading to wordpress 3.2.1. Having latest version means your site is updated and safe.

Now coming to the point, some of you might have faced this problem. You create a new page or post and do not want to allow comments on that. So you scroll down but cannot find the discussion box. The box which has 2 checkboxes “Allow comments” and “Allow trackbacks and pingbacks”.

To fix this, look at the top right of your screen for the Screen Options button. Click that and you will see a lot of checkboxes there. Click the Discussion  checkbox and close the screen options. Now scroll to bottom of the page and you will find the box sitting there.

WP3.2.1 has several other options like Custom fields, slug, Author which you can also enable from here.

Here is a small code snippet that will give you intersecting dates between 2 date ranges. Say, for example, you have 2 date ranges, 1-Jan-2011 to 31-Mar-2011 and 23-Feb-2011 to 4-May-2011.  This function will give you 23-Feb-2011 to 31-Mar-2011 as result.

Here is the code:

$a1  = "2011-01-01";
$a2  = "2011-03-31";
$b1  = "2011-02-23";
$b2  = "2011-05-04";

$intersection = getIntersection($a1,$a2,$b1,$b2);
if($intersection === false)
{
	echo 'No intersecting dates found';
}
else
{
	echo 'From '.date('d-M-Y', $intersection['start']).' till '.date('d-M-Y', $intersection['end']);
}

function getIntersection($a1,$a2,$b1,$b2)
{
	$a1 = strtotime($a1);
	$a2 = strtotime($a2);
	$b1 = strtotime($b1);
	$b2 = strtotime($b2);
	if($b1 > $a2 || $a1 > $b2 || $a2 < $a1 || $b2 < $b1)
	{
		return false;
	}
	$start = $a1 < $b1 ? $b1 : $a1;
	$end = $a2 < $b2 ? $a2 : $b2;

	return array('start' => $start, 'end' => $end);
}

Above will show the following on browser :

From 23-Feb-2011 till 31-Mar-2011

If the 2 date ranges have any intersecting dates, an array will be returned which will have start and end elements that represent the beginning and end of intersecting range.  Set of dates given below will return false as there are no intersecting dates.

$a1  = "2011-01-01";
$a2  = "2011-03-31";
$b1  = "2011-04-23";
$b2  = "2011-05-04";

$intersection = getIntersection($a1,$a2,$b1,$b2);

This will show

No intersecting dates found

The code is self-explanatory. As you can see, first we have used php function strtotime to convert all dates to timestamps. Then we can compare them easily. This way you can use whatever(allowed) date format you wish.

Recently I was contacted by Richard from Packt Publication to review their new book “Mastering phpMyAdmin 3.3.x for Effective MySQL Management“. Being a PHP-MySQL developer and an avid reader of technical books myself, I instantly agreed.

It took me a bit longer to read it then I had expected. At first, I had decided to just skim through the important chapters but it was interesting enough to change my decision. I then read all chapters one by one and realized that despite using phpMyAdmin on a daily basis, there is so much more to it that we developers are unaware of.

The author of this book is Marc Delisle, who is contributing to this project for more then 12 years. The book contains 19 chapters and 2 appendices. In my opinion the book can be divided broadly into 5 parts.

Chapter 1 to Chapter 3
I will say these warm up chapters as they cover installation, configuration and overview of phpMyAdmin interface in detail. Experienced users may skip these but beginners should go through each one of them.

I have combined the 2 previous posts for expanding and shortening goo.gl URLs and have created a small class for it. Below is the download link for the class.

Expanding a URL

<?php
include('GAPIClass.php');

$objAPI = new GAPIClass('your_api_key_here');
$result = $objAPI->expand('http://goo.gl/WlFX');
if(FALSE === $result)
{
	echo $objAPI->error;
}
else
{
	echo 'Long URL:'.$result;
}
?>

Shorten A URL

<?php
include('GAPIClass.php');

$objAPI = new GAPIClass('your_api_key_here');
$result = $objAPI->shorten('https://www.packtpub.com/php-jquery-cookbook-to-create-interactive-web-applications/book');

if(FALSE === $result)
{
	echo $objAPI->error;
}
else
{
	echo 'Short URL:'.$result;
}
?>

As I have mentioned earlier that Google recommends an API key. The class has a flag variable called keyWarning. By default it is true and it will show the following warning message if you do not pass an API key while instantiating the class:

Currently you are not using an API key. It is recommended that you use one. Click here to learn more about the API key

To turn this notification off, just use this line:

$objAPI->keyWarning = false;
