如何使用html表单提交多个数组复选框

<form action="your_processing_script.php" method="post">
 <input type="checkbox" name="array_name[]" value="value1"> Value 1<br>
 <input type="checkbox" name="array_name[]" value="value2"> Value 2<br>
 <input type="checkbox" name="array_name[]" value="value3"> Value 3<br>
 <input type="checkbox" name="array_name[]" value="value4"> Value 4<br>
 <input type="submit" value="Submit">
</form>

<?php
if (!empty($_POST['array_name'])) {
  $selected_values = $_POST['array_name'];
  foreach ($selected_values as $value) {
    echo "Selected value: " . $value . "<br>";
  }
} else {
  echo "No values were selected.";
}
?>
