CodeIgniter 4 Query Builder countAll()

The CodeIgniter 4 Query Builder countAll() function returns the count of rows in a table as an INTEGER. In this first example, we get the count of rows in the Sakila database ‘city’ table:

Number of rows in the city table is: 600

I have a story to tell. All about my journey as a self-taught backend web developer. Find out more in this interview I participated in over on the Real Tough Candy website. Read the entire interview here.

CodeIgniter 4 Query Builder countAllResults()

Where countAll() returns the number of rows in a specific table, countAllResults() returns the number of rows from a Query Builder query. You can use filtering functions with countAllResults() as well. In this example, I’m filtering the query using the where() function:

Number of rows in the actor table with actor_id less than or equal to 10 is: 10
