What are the potential drawbacks of using multiple MySQL queries instead of storing data in an array for targeted output in PHP?

Using multiple MySQL queries instead of storing data in an array can lead to increased database load and slower performance due to the additional queries being executed. To solve this issue, it is recommended to fetch all necessary data with a single query and then manipulate the data in PHP as needed. 

// Fetch all necessary data with a single query
$query = "SELECT * FROM table_name WHERE condition = 'value'";
$result = mysqli_query($connection, $query);

// Store the fetched data in an array
$data = [];
while ($row = mysqli_fetch_assoc($result)) {
    $data[] = $row;
}

// Manipulate the data as needed
foreach ($data as $row) {
    // Output targeted data from the array
    echo $row['column_name'];
}
