Question

I am trying to retrieve data from a query result. Now what I am trying is that if a question has no images, then just output a blank, else if a question does have image(s), then output the image using an image tag. Only problem though is that it keeps outputting Array.

Where am I going wrong?

<?php foreach ($arrQuestionId as $key => $question) { ?>

    <div class='lt-container'>

        <p><?php echo htmlspecialchars($arrQuestionNo[$key]) . ": " . htmlspecialchars($arrQuestionContent[$key]); ?></p>

        <?php
//start:procedure image
        $img_result = '';
        if (empty($arrImageFile[$key])) {
            $img_result = '&nbsp;';
        } else {
            ?>

            <p>
                <img alt="<?php echo $arrImageFile[$key]; ?>" height="200" width="200" src="<?php echo $arrImageFile[$key]; ?>">
            </p>

            <?php
        }
//end:procedure image
        ?>

    </div>

<?php } ?>
