How can the issue of receiving a boolean instead of a result set be resolved in the PHP code?

Issue: The problem of receiving a boolean instead of a result set in PHP code can be resolved by checking the return value of the query execution function. If the return value is a boolean, it means the query did not execute successfully. To resolve this issue, make sure the query is executed properly and handle any errors that may arise. 

// Execute the query
$result = mysqli_query($connection, "SELECT * FROM table");

// Check if the query executed successfully
if ($result === false) {
    die("Error executing query: " . mysqli_error($connection));
}

// Process the result set
while ($row = mysqli_fetch_assoc($result)) {
    // Do something with the data
}

// Free the result set
mysqli_free_result($result);
