No *real* reason - just two not-so-important ones:

1. Clarity
Please compare these two:
------ "MIXED"
<td bgcolor="<?php echo $td_col; ?>" class="<?php echo $prefclass; ?>">
<?php $fldcontent=$myrow[0]?$myrow[0]:"no data"; ?>
<input type="text" name="fname" size="50" value="<?php echo $fldcontent; 

------ "PURE"
  echo("<td bgcolor='$td_col' class='$prefclass'>\n");
  $fldcontent=$myrow[0]?$myrow[0]:"no data";
  echo("<input type='text' name='fname' size='50' value='$fldcontent'>\n");

The second is much easier to read and understand, you must agree.

2. Speed
There's an urban legend saying that switching php tags on and off would 
slow parsing down. I don't know if that's true and try to write "pure" 
php as you call it due to the first reason.
