Introduction to Technical Seminar Presentation on Object Oriented Features of PHP4:
The paper provides the object oriented features of PHP4. With the server side programming the static pages can be made dynamic so that an interaction with the database is possible. It behaves differently in case of different users. Also provides security to the applications viewed for the browser. And capable of processing the users data, also handles the compatibility related problems.
The different server side programming includes ASP, JSP, COLD FUSION and also PHP. And we have preferred PHP because it is stable i.e. There is no need to reboot the server very often, it is fast in its interpretation and it is easy i.e. the programming syntax is user friendly.
The PHP code is embedded in html code, the declaring the comments include single line (denoted with //) and multiline comments (/* */). The variables are denoted by dollar sign ($) and there is no need for the variables to be declared before it is being assigned. The operators which are used in the PHP includes ternary operators, logical operators, relational operators and string concatenation operator. The control structures include usage of IF, IF-ELSE AND ELSE-IF construct. The loop statements involve For, While, do-while loops and also involves the continue and break statement.
It supports the three-tier architecture of which includes Client tire, Application-server tire and also Data-server tire. Thus we can conclude that the paper provides the object oriented features of PHP4. With the server side programming the static pages can be made dynamic so that an interaction with the database is possible. It behaves differently in case of different users; all these features are made possible.
