In PHP, How Can We Obtain The Values Of Multiple Selections From A Select Box?

To get multiple selected values of a select box in PHP, you can use the $_POST or $_GET superglobal array depending on the method used to submit the form.

Here’s an example of how you can retrieve multiple selected values from a select box using the $_POST array:



PHP (process.php):

   if (isset($_POST['colors'])) {
      $selectedColors = $_POST['colors'];
      foreach ($selectedColors as $color) {
         echo $color . "<br>";

In this example, we use the name attribute of the select box as an array colors[] to allow multiple selected values. When the form is submitted, it will send an array of selected values to the process.php script. We can then retrieve the selected values by accessing the colors[] array in the $_POST array.

Please note that you should always sanitize and validate any user input before using it further to prevent security issues.
