Wordpress allows administrators to change the number of posts that are printed out on a page at once on the page Settings > Reading. However, this also has an impact on the number of search results that Wordpress will display. In order to keep the size of the home page down many Wordpress admins will reduce the number of articles to two or three. This can instantly make search results with only a few results reach many pages.

Every application has a locale, even if that is just the locale of the author. Through the use of locals you can make your application aware of what sort of language, currency and even timezone that the user would like to see. In Zend Framework this is accoumplished via Zend_Locale.

There are many things to do with locale once, but first you need to determine where the user is based. To find this out you simply create a new instance of the Zend_Locale object. The following code will create the Zend_Locale object and print out the language and region of the user.

The JavaScript Math.round() function will round a decimal to the nearest whole number, but I found that I needed was to round a number to the nearest 10. So after a bit of thinking I realised that I could divide the value by 10, round it using the round() function and then multiply the result by 10.

A prime number is a number which has exactly two distinct number divisors: 1 and itself. So if you take the number 11, it can only be divided to get a whole number if it is divided by 1 or 11. If any other number is used then a fraction is always found.

The following function uses a method called trial division to detect if a number is prime or not.

The isNaN() function (NaN stands for Not a Number) can be useful if you are looking at form inputs or similar and is used to detect if a value is not a number. For example, the following code shows the output of isNaN() on two variables.

To round a number in MS SQL use the ROUND() function. This function takes two parameters, the first is the number to be rounded and the second is the number of decimal places to round the number to. Here is an example of rounding the numbers in a column to the nearest whole integer.

SELECT ROUND(table.column1,0) rentValue FROM table
