What are the best practices for retrieving and displaying specific values from a field with multiple values in PHP?

When retrieving and displaying specific values from a field with multiple values in PHP, one common approach is to use the explode() function to split the values into an array based on a delimiter, such as a comma or a space. Once the values are in an array, you can access specific values by their index. To display the specific values, you can use a loop to iterate through the array and output the desired values. 

// Sample field with multiple values separated by a comma
$field = "value1,value2,value3";

// Split the field values into an array
$values = explode(",", $field);

// Display specific values from the array
foreach ($values as $value) {
    if ($value == "value2") {
        echo $value . "<br>";
    }
}
