result_first is a function in PHP that retrieves the first element from a MySQL result set. This function is often used when the query is expected to return only one row.
Example 1: $query = mysqli_query($connection, "SELECT name FROM users WHERE id=1"); $name = mysqli_result_first($query); echo $name; // Output: John
In this example, we use the result_first function to retrieve the name of the user with an ID of 1 from the users table.
Example 2: $query = mysqli_query($connection, "SELECT COUNT(*) FROM users"); $count = mysqli_result_first($query); echo $count; // Output: 10
In this example, we use result_first function to retrieve the number of rows in the users table using a COUNT query.
