How do we fetch the result of the query as an associative array in PHP?
To fetch the result of a query as an associative array in PHP, you can make use of the mysqli_fetch_assoc() function. This function retrieves the next row from a result set as an associative array, where the column names are used as keys.
Here's an example of how you can use this function:
php
// Establish a database connection
$conn = mysqli_connect("localhost", "username", "password", "database");
// Perform a query
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($conn, $query);
// Fetch the result as an associative array
$row = mysqli_fetch_assoc($result);
// Access the values using the column names as keys
echo "Name: " . $row['name'] . "<br>";
echo "Email: " . $row['email'] . "<br>";
In this example, we establish a database connection using the mysqli_connect() function. Then, we execute a query to select a single record from the "users" table where the id is 1. The mysqli_query() function is used to perform the query and store the result in the $result variable.
Next, we use the mysqli_fetch_assoc() function to fetch the result as an associative array. The returned array, $row, contains the column names as keys and the corresponding values from the result set.
Finally, we can access the values in the $row array using the column names as keys. In the example, we retrieve the "name" and "email" columns and display them using echo statements.
It's important to note that the mysqli_fetch_assoc() function returns the next row from the result set on each call. To retrieve subsequent rows, you can use a loop, such as a while loop, until all the rows have been fetched.
Using mysqli_fetch_assoc() provides a convenient way to access the result of a query as an associative array in PHP, allowing you to easily retrieve and manipulate the data.
