How can PHP be used to dynamically capture checkbox selections in an array?

To dynamically capture checkbox selections in an array using PHP, you can name all the checkboxes with the same name attribute followed by "[]" to indicate an array. When the form is submitted, PHP will automatically create an array with all the selected checkbox values. You can then access this array in your PHP script to process the selected values. 

<form method="post">
    <input type="checkbox" name="checkboxes[]" value="option1">
    <input type="checkbox" name="checkboxes[]" value="option2">
    <input type="checkbox" name="checkboxes[]" value="option3">
    <input type="submit" name="submit" value="Submit">
</form>

<?php
if(isset($_POST['submit'])) {
    $selectedCheckboxes = $_POST['checkboxes'];
    
    foreach($selectedCheckboxes as $checkbox) {
        echo $checkbox . "<br>";
    }
}
?>
