How to use PHP to develop the dish recommendation ranking function of the ordering system?

With the development of the Internet, various online ordering systems are becoming more and more popular. In order to improve user experience and increase sales, the dish recommendation ranking function has become one of the essential functions of many ordering systems. So, how to use PHP to develop the dish recommendation ranking function of the ordering system? This article will introduce it to you in detail.

First of all, we need to clarify the core elements of the dish recommendation ranking function. The dish rankings are mainly sorted based on user ordering behavior and reviews, and the most popular dishes will be ranked first. Therefore, we need to collect users’ ordering data and evaluation data, and calculate the ranking of dishes based on these data.

In PHP development, we can use the database to store the user's ordering data and evaluation data. First, we create a dish recommendation ranking table, which contains fields such as dish ID, name, order quantity, and evaluation score. Then, every time a user orders a meal or evaluates a dish, we update the data of that dish on the ranking list.

Next, we need to write PHP code to implement the dish recommendation ranking function. First, we need to connect to the database and write the relevant configuration parameters into the code. For example, database address, user name, password, etc.

Then, we can write a function to update the ranking data of the dishes. This function receives two parameters, one is the ID of the dish, and the other is the number of meals ordered or the score of the evaluation. Inside the function, we first query the data of the dish on the ranking list, and then update it based on the parameters passed in. Finally, the updated data is written to the database.

In addition to updating the ranking data of dishes, we also need to write a function to obtain the list of dishes on the ranking list. This function is mainly used to display on the front-end page of the ordering system. Inside the function, we can use SQL statements to query the top dishes list in the database. Then, the query results are returned to the front-end page for display.

In practical applications, we can also customize the display method of the dish rankings according to needs. For example, it can be ranked according to different time periods, or displayed according to different dish categories. These can be achieved by adding corresponding conditions in the SQL statement.

To sum up, it is not complicated to use PHP to develop the dish recommendation ranking function of the ordering system. We only need to connect to the database, write the corresponding SQL statements, and customize the display of the rankings. Through the dish recommendation ranking function, it can not only improve the user's ordering experience, but also increase the sales of dishes and enhance the commercial value of the ordering system.
