Web page optimizer
How to go from 15kb to a file of 11kb without even changing one single line in a CSS file? Without ruining the looks and comments of our page. How to keep them intact for editing and highly parsed, optimized for speed and compressed but only for the visitors?
Get the full URL of your page using PHP
Very often we need to have the ful URL of the page and use it somehow in our code, for example a dynamic script with social bookmarks or anything else we can think of. This can be done using Javascript but I prefer to use PHP since it's not based on the client side and it works with or without Javascript turned on in our browsers.
How to restrict visitor access to your web site
This tutorial by telling you that it's wrong to restrict access to your visitors.
PHP captcha verification
This way of preventing automated submissions is very used on the internet. More and more website owners start looking for a tool to prevent SPAM.I too have to delete about 200 SPAM messages a week submited through the comments area in this articles. The bad thing is that, if you don't do something to stop this spammers, the number will increase each day.
HTML to XHTML
This is a very handy function if you want to clean up your content before storing it into your database. It uses "eregi_replace" to replace every character with the desired one. I would use it to convert a HTML code to XHTML to make it valid.
Create social bookmarks
Social bookmarks is a thing you must have on your website if you want to increase the number of your returning visitors. More and more people rely on sites like del.icio.us or ma.gnolia.com to store their bookmarks. I use it too. It's safer this way. Why should I store my valuable bookmarks on my hard disk when I change my system at almost every 2 months due to viruses, errors or who knows what other reason. I always lose something.
Create tag cloud
You've seen it for the first time (as far as I know) on Flickr and you're seeing it on major websites as well. The "tag cloud" or "weighted words list" is nothing more than another way of displaying a navigation. It's funny, weird, new to the internet, attracts clicks, easy to do and it's also free.
Building multiple conditional statements in PHP
After building a condition, based on the result, PHP will alow you to chose what action to take.The condition itself can be anything you need or chose and you can build (combined) multiple conditions to get the thing working the way you want it.
