PHP DB limit is a database function used in PHP programming language that limits the number of results obtained from a database query. It's mainly used in situations where there is a large amount of data to be displayed and a limitation of how much should be displayed on a single page.
Suppose we have a database table named 'employee' that has thousands of records and we want to display only 20 records per page. We can use PHP DB limit to achieve this.
To retrieve the first 20 records from the employee table, we can use the following SQL query:
SELECT * FROM employee LIMIT 0, 20;
Here, the '0' represents the first record to be displayed while the '20' represents the number of records to be displayed.
To retrieve the next set of 20 records, the query should be:
SELECT * FROM employee LIMIT 20, 20;
Here, the '20' represents the starting point to display records from and the next '20' represents the number of records to display.
The PHP DB limit function is part of the PHP core library and does not require any additional package or library. Its use in conjunction with a database, however, requires a database library or extension such as MySQL, PostgreSQL, MongoDB, etc.
