PHP CRUD: Definition, practice and tutorials

for doing it Raw PHP This year technology increases and advances faster, as well as the advancement in the world of programming languages. People who work with databases will be familiar with PHP CRUD. Yes, this term is very familiar to developers, especially backend developers. Raw PHP CRUD is widely used to create programs that are dynamic in nature. Thus, the most popular and frequently used programming languages for this task are PHP and MySQL.

PHP Do you know PHP CRUD? What is CRUD?

Some of you are still curious about this word. This is especially true for those who have not yet learned much about TI. So it turns out that CRUD is short for the CRUD operations themselves: Create, Read, Update, Delete. In general, the CRUD operation itself is a process that involves transactions and data retrieval from a database. It is said that CRUD can also be used to define all important relational database functions and the applications used to manage them: Microsoft SQL Server, Oracle Database, MySQL, etc. PHP Crood For developers themselves, CRUD is important to learn when manipulating data, especially if you use PHP or MySQL databases. So it can be said that CRUD is an approach that combines and integrates PHP and MySQL programming language. According to the acronym, we can say that the purpose of CRUD is to read, insert, manipulate, edit and delete data from the table. So we can say that CRUD is important, right? Yes, because CRUD is closely related to the company's information system.

For a more detailed explanation, the PHP CRUD function is discussed below.

PHP CRUD operations

1. Create Creation means creation.

Well, the first step of CRUD is to create a new note or record in the database for the user to work with. When used in SQL relational database applications, the create operation is called an insert. The components of this first step are notes and objects. Here, notes indicate rows and items indicate used columns. So create here means that the user can create a new list that can be populated with data based on existing items. Therefore, it is also important to note that only administrators can fill in new items in that table.

2. to read

If read means read, function read: Well, in this case the PHP CRUD read function is to fetch data from the database. This download may only be possible if you are already logged in or have access to a specific site. So when you log in and go to the site, they read the data, right? The process of reading and confirming the account you entered will begin. In addition to that, the read function can be described as the search function, which allows you to search and read specific records. Therefore, users can search for the required records by directly entering the relevant keywords or filtering the data according to the set criteria.

3. Update

Since the current function is an update, you can use this PHP CRUD to modify or modify database records. So the first step to changing this record is to change the current information in several places. Therefore, this step requires you to identify the table or column you want to update. So in this update we need to merge the relevant values or rows so that the database will respond to the data updates made.

4. Delete

The last CRUD operation is delete. This feature allows you to delete unwanted database records. CRUD PHP In MySQLi, the delete function allows the user to delete more than one record from the database. Some database applications offer users the option of full deletion or soft deletion. Hard delete is a permanent delete, soft delete allows you to update rows without deleting and losing data.

These are some of the features of PHP CRUD. Then you will know more about the relationship between PHP MySQL CRUD. Next we will discuss how to create CRUD PHP and MySQLi.

– Create the database.sql

The first step you can take is to create the first Database.sql. Then use phpMyAdmin to import the database into Database.sql. Also, note that table elements and content allow users to enter an ID, name, email, mobile number, etc.

– Create the config.PHP file Next you can create the config.PHP file.

This file is used to store information about the host database, username or password. In general, some local servers will work based on the information provided, but this can be changed depending on the host and database information. Later, when you connect PHP and MySQL, you can use the MySQL_connect() function, which takes the server address as the main parameter, and the second parameter is the database user, which is the third and fourth database user passwords. data is the name of the database. . You can enter the password yourself depending on what the server does, but if you don't use a password you can enter it as an empty string. Raw PHP – Create the index.PHP file You can create an index.PHP file. In this file you can use a MySQL select query to see a list of all users.

– Create add.PHP file Next, the add.PHP file created a function to add new users.

– Create an edit.PHP file. As the file title suggests, edit.PHP is used to edit or update user data.

– Create a delete.PHP file. The next step, and final step, is to create a delete.PHP file that will be used to delete the selected users by clicking the delete link. that
