1. About SQL injection So far, I have not seen who wrote a very complete article, or a very mature solution (can do a lot of people, the problem is not spread out, very sorry) I simply said a few, hope to inspire people to think, play a role in the discussion First, the principle of SQL injection The implementation

developers the opportunity to capture any errors (when a PDOException exception is thrown ). The setAttribute () line is mandatory. It tells PDO to disable the simulation of the pre-Definition Statement and use the real pre-Definition Statement. This ensures that the statements and values are not parsed by PHP before being sent to the MySQL database server (attackers have no chance to inject malicious

MySQL database, the true pre-definition statements are not used by default! To solve this problem, you must disable the statements prepared by simulation. Example of using PDO to create a connection: $ dbConnection = new PDO ('mysql: dbname = dbtest; host = 127.0.0.1; charset = utf8', 'user', 'pass '); $ dbConnection-> setAttribute (PDO: ATTR_EMULATE_PREPARES, false); $ dbConnection-> setAttribute (PDO: ATTR_ERRMODE, PDO: ERRMODE_EXCEPTION ); in the

This paper describes the simple implementation of SQL anti-injection method in PHP. Share to everyone for your reference, as follows: There is not much filtering here, mainly for PHP and MySQL combination. General anti-injection, as long as the use of PHP addslashes function is possible. Here's a copy of the code: PHP Code: $_post = Sql_injection ($_post); $_ge

Summary of five methods to effectively prevent SQL injection, and 5 methods to effectively prevent SQL Injection SQL Injection SQL injection

some time ago, in a lot of blogs and micro-blog burst out of the 12306 some loopholes in the website of the Ministry of Railways, as such a large project, it is not impossible to say that there are loopholes, but the loopholes are some novice programmers will make mistakes. In fact , the SQL Injection vulnerability is one. As a rookie little programmer, I know nothing about

SQL injection focuses on the construction of SQL statements, only the flexible use of SQL Statement to construct the injected string of the bull ratio. After finishing the study, I wrote some notes, ready to use. I hope you're looking at the following. The rationale for solving SQL
