Aim of this diploma thesis is study of possibilities of OpenSSL extension in PHP environment and its implementation in securing client-server system example. This system will be use to store confidential data. Whole system will be exemplar of securing against scale of attacks leads to gain private data.

Darbas skirtas sukurti Ikimokyklinių įstaigų kontingento formavimo ir vaikų lankomumo apskaitos sistemas. Darbo metu buvo atlikta klijento (Kretingos švietimo skyriaus) poreikių analizė, bei sukurtas duomenų bazės projektas. Buvo realizuota Ikimokyklinių įstaigų kontingento formavimo ir vaikų lankomumo apskaitos sistema su duomenų baze. Ši sistema leidžia registruoti vaikus, bei sudarinėti eiles ir kartu žymėti vaikų lankomumą. Šiuo metu šią sistema naudoja Kretingos švietimo skyrius, bei jam priklausančios mokyklos. / The purpose of this work is to develop a system for contingent forming and attendance accounting in pre-schools. In the flow of this work, an analysis of clients (Kretinga's scool-board) needs was preformed and a project of database was created. A system for contingent modeling and attendance accounting in gradeschool institutions was implemented along with a database. This system allows to register children and form line-ups herewith accounting children's attendance. At the time this system is used by Kretinga's school-board along with the relyent schools.

Šiuo metu yra sukurta daugybė PHP karkasų, tačiau yra mažas informacijos kiekis subjektyviai nusakančios privalumus ir trūkumus. Pagrindinis darbo tikslas yra ištirti Yii, Zend 2 ir Symfony2 karkasus, bei juos palyginti. Šiame dokumente aprašytas darbas susideda iš trijų pagrindinių dalių. Pirmoji dokumento dalis – karkasų apžvalga. Šioje dalyje apžvelgiami Yii, Zend 2 ir Symfony2 karkasai. Antrojoje (projektinėje) dokumento dalyje aprašoma sistema, kuri yra kuriama atskirai su kiekvienu iš karkasų. Šiame skyriuje pateikiama visa sistemos architektūra, reikalavimai sistemai, bendri apribojimai, statinis vaizdas. Trečioje (tyrimo ir eksperimentinėje) dokumento dalyje, detalizuojami atlikti tyrimai ir eksperimentai. Tyrimai vykdomi kuriant QR kodų generavimo ir vartotojų lankomumo statistikų sekimo sistemą. Šių tyrimų metu tiriamas darbo imlumas, našumas, funkcionalumas ir atlikta pasirinktų karkasų kodo analizė. / Currently there are created plenty of different PHP frameworks, but the amount of information subjectively outlining the pros and cons is low. Main purpose of this research is to investigate and compare three main frameworks: Yii, Zend 2 and Symfony. This document describes work consisting of three main parts. The first part of the document is a framework review. This section provides and overview of Yii, Zend 2 and Symfony2 frameworks. Second (design) part is a description of the system which was developed using each of the frameworks. This section contains the entire system architecture, system requirements, general restrictions and static image. The third (research and experimental) part of the document, consists of detailed studies and experiments. Studies were carried out in developing QR code generation and visitor monitoring system. During these studies the capacity, performance, functionality and code of three main frameworks were analyzed.

The primary motivation for writing the thesis Modern Object Oriented XML API for PHP was absence of PHP API which would be easy to use, correct and complete. This thesis analyzes the flaws of current PHP APIs and describes how they are solved in modern APIs in other programming languages. It also presents an in-depth description of XML language and its associated standards. Using the knowledge gained from the analysis, the thesis proposes a new API called phpxom based on Java API XOM. The API is then implemented according to the proposal. The resulting PHP library has all the required features -- easiness of use, correctness and completeness. Finally, the thesis analyzes the possibility to implement phpxom as a PHP extension written in C language, which would make it faster and lower its memory requirements.
