With the popularization of college education, graduation project has become a task that every college student must face. Graduation design topic selection is a key step in the entire graduation design process. Choosing the right topic will lay the foundation for the subsequent graduation design process. The traditional method of selecting topics for graduation projects is generally to manually fill in the topic application form, which is inefficient and error-prone. Now, with the development of computer technology, using PHP language to build an online graduation project topic selection system has become a quick solution.
Using PHP language to build an online graduation project topic selection system requires the following steps:
1. Establish a database
First, you need to create a database to store information related to topic selection. . In the MySQL management interface, create a new database named "graduation_design". Then create the following four data tables in the database.
2. Build a website
Using PHP language to build a graduation project topic selection system requires the use of programmers' development technology to build a complete website. You can find some template files for graduation project topic selection systems online to use, or you can develop them yourself according to your needs. The Bootstrap framework can be used for rapid design and development during the development process.
define('DB_HOST','localhost');
define('DB_USER','root');
define( 'DB_PASS','');
define('DB_NAME','graduation_design');
When connecting to the database, you can use the "try...catch" statement to catch exceptions if the connection fails. , error information can be output, as shown below:
try{
$pdo = new PDO('mysql:host='.DB_HOST.';dbname='.DB_NAME,DB_USER,DB_PASS);
}catch(PDOException $e){
echo '数据库连接错误:'.$e->getMessage();
}
