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.
PHP: session_start() – No such file or directory error
Have you encountered the following PHP error (or something similar) before in your Windows Vista?
Warning: session_start() [function.session-start]: open(C:\Users\YOURNAME\AppData\Local\Temp\php\session\sess_ficdel21e6lupsojqdk62ofts5, O_RDWR) failed: No such file or directory (2) in C:\webapp\folder\index.php on line 24
The solution to the above error is really simple. Simply re-create the folder C:\Users\YOURNAME\AppData\Local\Temp\php\session\. For some reason, you or your Windows Vista (e.g. during a disk cleanup) may deleted all the files and folder under C:\Users\YOURNAME\AppData\Local\Temp\ and this is the main reason PHP can't find the correct location to create its temporary file for new session.
