What is the purpose of the multiple selection list in PHP and how is it populated from an array?

The purpose of a multiple selection list in PHP is to allow users to select multiple options from a list. To populate a multiple selection list from an array, you can use a foreach loop to iterate over the array and create an option element for each item in the array. 

<select name="options[]" multiple>
<?php
$options = array("Option 1", "Option 2", "Option 3");

foreach($options as $option) {
    echo "<option value='$option'>$option</option>";
}
?>
</select>
