LEARN ABOUT PHP

fgetss

FGETSS(3)								 1								 FGETSS(3)

fgetss - Gets line from file pointer and strip HTML tags

SYNOPSIS

       string fgetss (resource	$handle, [int  $length], [string  $allowable_tags])

DESCRIPTION

	Identical to fgets(3), except that fgetss(3) attempts to strip any NUL bytes, HTML and PHP tags from the text it reads.

PARAMETERS

	      o $handle
		-The  file  pointer must be valid, and must point to a file successfully opened by fopen(3) or fsockopen(3) (and not yet closed by
		fclose(3)).

	      o $length
		- Length of the data to be retrieved.

	      o $allowable_tags
		- You can use the optional third parameter to specify tags which should not be stripped.

RETURN VALUES

	Returns a string of up to $length - 1 bytes read from the file pointed to by $handle, with all HTML and PHP code stripped.

	If an error occurs, returns FALSE.

       Example #1

	      Reading a PHP file line-by-line

	      <?php
	      $str = <<<EOD
	      <html><body>
	       <p>Welcome! Today is the <?php echo(date('jS')); ?> of <?= date('F'); ?>.</p>
	      </body></html>
	      Text outside of the HTML block.
	      EOD;
	      file_put_contents('sample.php', $str);

	      $handle = @fopen("sample.php", "r");
	      if ($handle) {
		  while (!feof($handle)) {
		      $buffer = fgetss($handle, 4096);
		      echo $buffer;
		  }
		  fclose($handle);
	      }
	      ?>

	      The above example will output something similar to:

	      Welcome! Today is the  of .

	      Text outside of the HTML block.

NOTES

       Note

	      If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh  computer,  enabling  the
	      auto_detect_line_endings run-time configuration option may help resolve the problem.
