How can PHP developers ensure proper syntax when including HTML elements like checkboxes in PHP output?

When including HTML elements like checkboxes in PHP output, developers can ensure proper syntax by properly escaping the HTML code using functions like `htmlspecialchars()` to prevent any syntax errors or vulnerabilities. This function will convert special characters to their HTML entities, ensuring that the HTML code is rendered correctly in the output. 

<?php
$checkbox_value = "example_checkbox_value";
$checkbox_text = "Example Checkbox";

// Output the checkbox with proper syntax
echo '<input type="checkbox" name="checkbox_name" value="' . htmlspecialchars($checkbox_value) . '">' . htmlspecialchars($checkbox_text);
?>
