What are some best practices for handling multiple MySQL data records in PHP and merging them into a single table entry?

When handling multiple MySQL data records in PHP and merging them into a single table entry, it is important to retrieve the data records, process them accordingly, and then combine them into a single entry in the database table. One way to achieve this is by using a loop to iterate through the data records, extract the relevant information, and then insert or update the combined data into the database table. 

// Assume $dataRecords is an array of multiple MySQL data records

// Initialize an empty array to store the combined data
$combinedData = [];

// Iterate through each data record
foreach ($dataRecords as $record) {
    // Process the data record and extract relevant information
    $data = [
        'field1' => $record['field1'],
        'field2' => $record['field2'],
        // Add more fields as needed
    ];
    
    // Merge the extracted data into the combined data array
    $combinedData[] = $data;
}

// Insert or update the combined data into the database table
// Assuming $mysqli is a mysqli object connected to the database
foreach ($combinedData as $data) {
    $query = "INSERT INTO table_name (field1, field2) VALUES ('" . $data['field1'] . "', '" . $data['field2'] . "')";
    // Execute the query using $mysqli->query($query)
}
