In PHP, how can one efficiently separate and process multiple values stored in a comma-separated format in a database column?

When dealing with multiple values stored in a comma-separated format in a database column, it is efficient to use the explode() function in PHP to separate these values into an array. This allows for easier processing and manipulation of the individual values. Once the values are separated, you can loop through the array to perform any necessary operations.

// Retrieve the comma-separated values from the database
$values = "value1,value2,value3";
$valueArray = explode(",", $values);

// Loop through the array to process each value
foreach ($valueArray as $value) {
    // Perform operations on each value
    echo $value . "<br>";
}
