How can PHP be used to set a checkbox as checked when a specific condition is met?

To set a checkbox as checked in PHP when a specific condition is met, you can use the ternary operator within the HTML input tag. This allows you to check the condition and set the "checked" attribute accordingly. By evaluating the condition within the input tag, you can dynamically set the checkbox as checked or unchecked based on the condition. 

<?php
$condition = true; // Example condition

// Use the ternary operator to set the "checked" attribute based on the condition
$checked = $condition ? 'checked' : '';

// Output the HTML input tag with the "checked" attribute dynamically set
echo '<input type="checkbox" name="checkbox_name" value="1" ' . $checked . '>';
?>
