PHP: Format integer into number of decimal places
Previous I have written an article about formating interger into number of decimal places in Java. The main reason to store money value in integer in to prevent loss in precision. For example the actual value for 12.33 in float could be 12.3333333333...; while 1233 in integer is always 1233.
Today I will be showing you the same code but in PHP language. I know you can do the same thing with PHP's number_format(), but you will need to cast the integer into float first before past the money value into the number_format() function. Therefore there are possibles of lose in precision.

C#: Unix Time to .Net DateTime and Vice Versa

How Do You Know When Your Site Get Indexed in Google Search Engine?
How do you know when your site get indexed in Google search engine. You can actually use Google search engine to find out how your site is indexed. For example:
- to know the indexed pages in www.snipetit.com, simply query site:www.snippetit.com at Google search engine.
- to know the pages that link to your www.snipetit.com's front page, simply query link:www.snippetit.com at Google search engine.
- to know the current cache of www.snipetit.com's front page, simply query link:www.snippetit.com at Google search engine.
- to know the information of www.snipetit.com's front page, simply query info:www.snippetit.com at Google search engine.

Java: Randomly sort values in a array (the generic way) in single pass
Few years back (yes, about 4 years back), I wrote an article about randomly sort query results in MySQL. The main problem in randomly sort query results is that when you have a very large data in your database and the statement to sort the result may change the data execution plan causing DMBS does not choose the right plan. Therefore, sometime it is more wise to sort it in your own program instead of too depending on DBMS's decision which may affect the overall performance of a program.
Java: Format integer into number of decimal places and performance
For certain reasons (e.g. precision issue), some programmer may store a float value (e.g. money) in integer variable. For example -12345678.90 is stored as -1234567890. To convert the integer value to number with number of decimal places is a problem.
There are several way to do it. You can simply use the Java's String.format(), DecimalFormat or Float.toString(). Most of them does not meet my requirements: Simple, fast, precise and with thousand separator. Therefore I wrote a simple class that ease myself.
