What are common issues when using checkboxes in PHP forms?

One common issue when using checkboxes in PHP forms is that unchecked checkboxes do not get submitted in the form data. To solve this, you can use an array for the checkbox input name attribute and check if the checkbox is checked before processing the form data. 

// Example of handling checkboxes in PHP form submission
if(isset($_POST['checkbox'])) {
    // Checkbox is checked
    $checkboxValue = $_POST['checkbox'];
} else {
    // Checkbox is unchecked
    $checkboxValue = '';
}
