PHP CRUD Operations: Complete Guide

In PHP, the methods for CRUD operations are usually implemented using the database operation language SQL. Common database operation statements include:

1. Add data: use the INSERT INTO statement to insert new records into the database.

Insert values into the specified columns in the table.

1. Delete data: Use the DELETE FROM statement to remove specific records from the database.

Remove from table_name where the condition is met.

1. Modify data: Use the UPDATE statement to make changes to existing records in the database.

Modify table_name by setting the value of column1 to value1 and column2 to value2 under the specified condition.

1. Retrieve data: Use the SELECT statement to fetch data from the database.

Choose column1 and column2 from table_name based on a certain condition.
