PHP is a powerful but easy-to-learn server-side scripting language. Even a few experienced programmers can use it to create complex dynamic web sites. However, it often has many difficulties in realizing the secrets and security of Internet services. In this series of articles, we will introduce you to the security background necessary for web development and the specific knowledge and code of PHP-you can protect the security and consi
SQL injection attacks are not a new topic. I believe many of my friends are no longer troubled by this issue. However, if you do not pay attention to it in some places, there are still vulnerabilities to be found. Therefore, you can use the following statements to construct an SQL query.

SQL injection attacks are the most common means for hackers to attack websites. If your site does not use strict user input tests, it is often vulnerable to SQL injection attacks. SQL

PHP's MySQL extensions. Fortunately, by default, it is not allowed to execute multiple instructions in a single query; Attempting to execute two directives (such as the one shown above) will simply result in failure-no errors are set and no output information is generated. In this case, although PHP is just "behaving" to its default behavior, it does protect you from most simple injection
Talking about preventing SQL injection attacks, feeling very depressed, so many years have been discussed, but also has been arguing, but now seems to have no conclusion. When you do not know the principle of injection will feel very magical, how has been injected? Will find it difficult to prevent. But is it easy to p

There are two ways to prevent SQL injection attacks:
1) The first is that all SQL statements are stored in the stored procedure, which not only avoids SQL injection, but also improves performance. In addition, the stored procedur
