Question
Explain the difference between Function mysqli_fetch_row () and mysqli_fetch_assoc ()? (2 points)
Solution
The main difference between the mysqli_fetch_row() and mysqli_fetch_assoc() functions in PHP lies in the way they return data from a database query.
-
mysqli_fetch_row(): This function returns a numerical array of values. Each value in the array corresponds to a column's value in the row from the database. The array indices are numerical and start from 0. For example, if you have a table with columns 'id', 'name', and 'email', the function will return an array like [1, 'John', '[email protected]'].
-
mysqli_fetch_assoc(): This function returns an associative array of values. Each value in the array corresponds to a column's value in the row from the database. The array indices are the column names. So, for the same table, the function will return an array like ['id' => 1, 'name' => 'John', 'email' => '[email protected]'].
In summary, mysqli_fetch_row() returns a numerical array while mysqli_fetch_assoc() returns an associative array with column names as keys.
