How can PHP be used to correctly evaluate and display data stored in a SET field type in MySQL for a survey with multiple selections?

To correctly evaluate and display data stored in a SET field type in MySQL for a survey with multiple selections, you can use the MySQL FIND_IN_SET function in your PHP code. This function allows you to search for a value within a comma-separated list of values stored in a SET field. You can then use this function to determine which options were selected in the survey and display them accordingly.

// Assume $selectedOptions contains the comma-separated list of selected options from the SET field in MySQL
$selectedOptions = "Option 1,Option 3";

// Retrieve the options available in the SET field from the database
$options = ["Option 1", "Option 2", "Option 3", "Option 4"];

// Loop through each option and check if it is selected
foreach ($options as $option) {
    if (strpos($selectedOptions, $option) !== false) {
        echo $option . " was selected <br>";
    }
}
