Suppose we have a "new.html" file with the following content. The Chinese translation of

<p><strong>Asia</strong> is a <em>continent</em>.</p>

Example

is:

Example

<?php
   $file_pointer= fopen("new.html", "rw");
   echo fgetss($file_pointer);
   fclose($file_pointer);
?>

The following is the output result. We didn't add parameters to avoid stripping HTML tags, so the output looks like this:

Output

Asia is a continent.

Now, let us see another example wherein we have the same file, but we will add the length and HTML tags parameters to avoid stripping of those tags. The Chinese translation of

Example

is:

Example

<?php
   $file_pointer = @fopen("new.html", "r");
   if ($file_pointer) {
      while (!feof($handle)) {
         $buffer = fgetss($file_pointer, 1024"<p>,<strong>,<em>");
         echo $buffer;
      }
      fclose($file_pointer);
   }
?>

Output

Asia is a continent.
