Research And Design Of P2P Lending System Based On PHP

The level of development of the traditional financial services industry is not high efficient and slow growth. For individuals, the countryside and small business, the supply of financial services lagged far behind, and the traditional financial industry for microcredit exists inefficient, cumbersome, long lending period and other shortcomings, leading to many small loans from banks is difficult to credit, P2 P lending is developed under this circumstance.P2 P lending provides third-party with loans and borrowings through a network of financial technology network platform. P2 P lending establishes a very efficient communication platform for Investors and borrowers as a financial network and the combination of emerging industries.This article introduces the development of P2 P lending industry and practical value of P2 P lending system in depth. The system platform is based on B/S architecture, using PHP technology as the primary programming language, taking open source database Apache as the PHP interpreter, MySQL as the network database server, through the use of ThinkPHP framework technology and WAMP Integrated Development Environment, not only enhance the efficiency of system development, but also reduces the difficulty of system maintenance. This article introduces the analysis and design of system according to the actual needs of P2 P network lending, including loan process analysis and investment process analysis of P2 P lending system, and designs the corresponding flow diagram. Analysis the front desk and backstage function requirements. Introduces the development process and implementation process of the whole system, and design the front desk and backstage function module, the system function module is clear and reasonable. Design the main functional sequence diagram, analysis and design of database system in detail. Research on the potential security problem of P2 P lending platform, In view of the SQL injection security issues suggest by use of database design skills, security configuration and other methods to defensive. In view of the cross-site scripting attacks suggest by use of filtering input and output verification methods to defensive.Through continues system debugging and testing prove that the system has good compatibility, security and ease of use features, able to meet the requirements, promote the development of P2 P lending industry.
