Question

I'm trying to if else condition inside echo.

<?php if(count($category['children'][$i]['children_level2'])>0){ ?>
      <a href="<?php echo $category['children'][$i]['href']; ?>"><?php echo $category['children'][$i]['name']; ?>
    <?php echo "<?php if ($direction == 'ltr') { ?><span class='fa fa-caret-right'></span><?php } else { ?><span class='fa fa-caret-left'></span><?php } ?></a>";
    } else{ ?>
      <a href="<?php echo $category['children'][$i]['href']; ?>"><?php echo $category['children'][$i]['name']; ?></a>
    <?php }?>

but, following condition is not work properly in above code. What is wrong here?

<?php if ($direction == 'ltr') { ?><span class='fa fa-caret-right'></span><?php } else { ?><span class='fa fa-caret-left'></span><?php } ?>
