What are some common pitfalls to avoid when working with PHP loops and conditional statements in generating HTML elements like checkboxes?

One common pitfall to avoid when working with PHP loops and conditional statements in generating HTML elements like checkboxes is forgetting to properly concatenate the HTML output within the loop. This can result in only the last iteration of the loop being displayed on the webpage. To solve this issue, make sure to concatenate the HTML output within the loop to ensure all iterations are displayed correctly. 

<?php
// Example of generating checkboxes using a loop with proper concatenation

$checkboxes = array("Option 1", "Option 2", "Option 3");

// Loop through the checkboxes array
foreach ($checkboxes as $checkbox) {
    // Check if the checkbox should be checked based on a condition
    $checked = ($checkbox == "Option 2") ? "checked" : "";

    // Output the checkbox HTML with proper concatenation
    echo '<input type="checkbox" name="checkbox[]" value="' . $checkbox . '" ' . $checked . '>' . $checkbox . '<br>';
}
?>
