Counting Rows in CodeIgniter

To count the number of rows in a database table using CodeIgniter, you can follow these steps:

Step 1: Load the database library in your controller or model. This library provides the necessary functions to interact with the database.

$this->load->database();

Step 2: Use the count_all() method of the active record class to get the row count. The count_all() method returns the total number of rows in a given table.

$this->db->count_all('table_name');

Replace 'table_name' with the actual name of the table you want to count rows from.

Step 3: Store the result in a variable if you need to use it later.

$row_count = $this->db->count_all('table_name');

The variable $row_count will now hold the total number of rows in the specified table.

Step 4: You can then use the value of $row_count as per your requirements. For example, you can display it on a webpage or use it in a conditional statement.

echo "Total rows: " . $row_count;

This will output the total number of rows in the table.

That's it! You have successfully counted the number of rows in a database table using CodeIgniter. Remember to replace 'table_name' with the actual name of your table.
