What are some best practices for handling data retrieval and processing in PHP when dealing with multiple values in a single cell?

When dealing with multiple values stored in a single cell in a database, it is best practice to separate these values using a delimiter (such as a comma) and then retrieve and process them accordingly in PHP. This can be achieved by using PHP's explode() function to split the string into an array of values. This allows for easier manipulation and handling of the individual values. 

// Retrieve the data from the database
$data = "value1,value2,value3";
$values = explode(",", $data);

// Process the values
foreach ($values as $value) {
    // Do something with each value
    echo $value . "<br>";
}
