Answer 1

您可以像这样将 html 代码放在 echo 中

 echo "<tag name></tag name>"

Answer 2

Read about string concatenation in PHP.

Here is a possible solution for your problem:

<?php
if ($row['user_id'] === 1) {
  echo '<a href="/members/delete/'.$row['user_id'].'">'.$row['username'].'</a>';
}

Answer 3

I think you want to add variables in string:

<?php
if ($row['user_id']==1){
echo '<a href="'.site_url('members/delete/'.$row['user_id']).'" class="btn btn-danger" onclick="return confirm(\'Are you sure to delete?\')">delete</a>';
}
?>

Use . to combine strings & variables:

 'string'.$var

here an an example...

<?php if ($row['user_id']==1){ ?>
<a href="<?php echo site_url('members/delete/'.$row['user_id']); ?>" class="btn btn-danger" onclick="return confirm('Are you sure to delete?')">delete</a>
<?php } ?>
