Web technologies, as the name indicates are the technology used over the world wide web. These technologies help the users to communicate with each other. You may have learned in your social sciences subject that Language is the main source of communication. Similarly when computers communicate, they also use certain specific language or languages for this.  As we all know HTML is the hypertext markup language. It is the core of web technologies.

So how could we find if a word or a sentence is palindrome or not? We will use php for this... code: <?php function semiPermeableMembrain ( $str ){ $str = strtolower( $str ); $split = str_split ( $str ); foreach ( $split as $obstacle ){ if ( $obstacle == " " || $obstacle == "'" || $obstacle == "." || $obstacle == "," || $obstacle == ";" || $obstacle == ":" || $obstacle == "-" ) { $obstacle = "/ $obstacle /" ; $str = preg_replace ( $obstacle , '' , $str ); } } palindrome( $str ); ...

As we have learned much of the basics of  HTML and CSS . Let us now learn how can we make our web applications more user friendly, flexible and versatile, using php . Today we will see how to make a chess board using php in collaboration with HTML and CSS .  So, Let's start: BASIC php SYNTAX: Starting Closing Tags: <?php ?> Php code must be written in these tags. Variables:              Start with "$" sign e.g. $num=3;               ; is really important to put after every statement. Functions:              Functions start with the keyword "function". E.g. function power(){} Print:             echo "printing by using echo";             echo ("printing by using echo");             print "pri...
