In what scenarios would utilizing GROUP BY in a SQL query be considered a workaround rather than a solution to fetching specific data from multiple tables in PHP?

When utilizing GROUP BY in a SQL query to fetch specific data from multiple tables in PHP, it may be considered a workaround rather than a solution if the query is causing duplicate or incorrect results due to the grouping of data. This can happen when the GROUP BY clause is used incorrectly or when it is not necessary for the desired result. In such scenarios, it is better to review the query logic and possibly restructure it to fetch the specific data without relying on GROUP BY. 

$query = "SELECT t1.column1, t2.column2
          FROM table1 t1
          JOIN table2 t2 ON t1.id = t2.id
          WHERE t1.condition = 'value'";

// Execute the query and fetch specific data without using GROUP BY
$result = mysqli_query($connection, $query);

if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process fetched data here
    }
} else {
    echo "No results found.";
}
