One of the biggest annoyances with CSS is the inability to apply more than one background image to a box.
I’m currently working on a site that is in particular need of this. The only way to tackle it, at the moment, is to throw an ass-load of span or div tags in the mix (or to rely on tags that are slightly more meaningful, if they’re appropriate, but that’s not always possible). Continue Reading

Remember to check numeric data as well. If an application generates a query such as SELECT * FROM table WHERE ID=234 when a user enters the value 234,the user can enter the value 234 OR 1=1 to cause the application to generate the query SELECT * FROM table WHERE ID=234 OR 1=1.As a result, the server retrieves every row in the table. This exposes every row and causes excessive server load. The simplest way to protect from this type of attack is to use single quotes around the numeric constants: SELECT * FROM table WHERE ID='234'. If the user enters extra information, it all becomes part of the string. In a numeric context, MySQL automatically converts this string to a number and strips any trailing nonnumeric characters from it. It means that if the user enters 234myname the value remains 234. Another option is to do a check before the mysql query if the value is numeric.

suppose you want /articles.php?cat=$1&art=$2 to become magazine/1/2
then you need these two rules:
#articles.php?cat=$1&art=$2
RewriteRule ^magazine/([^/]*)/([^/]*)$ /articles.php?cat=$1&art=$2&marker [L]
RewriteCond %{REQUEST_URI} /articles\.php [NC]
RewriteCond %{QUERY_STRING} ^cat=(.*)&art=(.*)
RewriteCond %{QUERY_STRING} !marker
RewriteRule (.*) http://mydomain/%1/%2? [R=301,L]

Unique Visitor:
A unique visitor is a host that has made at least 1 hit on 1 page of your web site during the current period shown by the report. If this host make several visits during this period, it is counted only once.
The period shown by AWStats reports is by default the current month.
However if you use AWStats as a CGI you can click on the “year” link to have a report for all the year. In a such report, period is full year, so Unique Visitors are number of hosts that have made at least 1 hit on 1 page of your web site during those year. Continue Reading
