timestamp with day light saving for different timezone

Timestamp is a fixed time interval from unix epoch. It will be same for all the different timezones. We will get the same timestamp output for time(), mktime() or gmmktime().
If we use arguments with mktime() or gmmktime(), then the timestamps may vary. So, we will use the Timezone features that is added on PHP 5.3. This is eliminate any differences of timestamp related problems.

increase file upload size in dream host

If you are using shared hosting from Dreamhost, then you don't have root access. When you want to increase the file upload size for PHP, then we need to follow their way for increasing the file upload size.
Let's increase our file upload size in the following way:

mkdir ~/[your website directory]/cgi-bin

create a file called php-copy.sh and put it in your website directory.
If we use PHP5, then we will add the below code block into the file:

#!/bin/sh
CGIFILE="$HOME/[your website directory]/cgi-bin/php.cgi"
INIFILE="$HOME/[your website directory]/cgi-bin/php.ini"
rsync -a /dh/cgi-system/php5.cgi "$CGIFILE"
# REMOVE THE FOLLOWING LINE TO CREATE THE UPDATE-ONLY SCRIPT:
cp /etc/php5/cgi/php.ini "$INIFILE"

perl -p -i -e '
s/.*post_max_size.*/post_max_size = 100M/;
s/.*upload_max_filesize.*/upload_max_filesize = 100M/;
' "$INIFILE"

Notice how in these lines it is set to 100M

Standard Form Markup

We have a confusion over what will be our best HTML form markup. I have faced this problem recently. So, I am sharing my experiences here.

Semantic Markup

First of all we can use the normal HTML elements to create a simple form. Below is the code block for this:

 

  
Legend Name
  Name
  
 

Definition List

Now, we can have a full control of our HTML markup elements using the definition list. It's more flexible than the previous structure. Let's see the code below:

 

  

   
Name
   

  
 

With this structure, we can apply CSS style to the elements. We will apply float: left and a common width to dt. And float: right and a common width to dd. To remove all the styling of dt and dd we apply clear style to dl. This will give us a two column layout structure.
I prefer this option, though there are many ways to have the same look and fill, but this is the simplest and effective way.
