How can data from a related table be stored in an array to avoid repetitive queries in PHP?

To avoid repetitive queries when fetching data from a related table in PHP, you can store the related data in an array. This way, you only need to query the related table once and then access the data from the array whenever needed. This can help improve performance and reduce the number of database queries made. 

// Assume $relatedData is an array containing data from a related table
$relatedData = [];

// Query the related table and store the data in the array
$query = "SELECT * FROM related_table";
$result = mysqli_query($connection, $query);
while ($row = mysqli_fetch_assoc($result)) {
    $relatedData[$row['id']] = $row;
}

// Access the related data from the array
$relatedId = 1;
echo $relatedData[$relatedId]['column_name'];
