I express my sincere thanks to my guide Mr. Manish Shandilya (Web page developer in PHP, Bikaner), for guiding me right from the inception till the successful completion. I sincerely acknowledge him for extending his valuable guidance, support for literature, critical reviews on PHP (PHP: Hypertext Preprocessor) and the report and above all the moral support he had provided me with all stages of this topic. Thanks also too many people who provided detailed reviews on the topic PHP (PHP: Hypertext Preprocessor) and thanks also to the people who are responsible for the publication of the report.

Finally, with all this assistance, little remains for which I can take full credit.
