fgetss â Gets line from file pointer and strip HTML tags
Description
string fgetss ( resource $handle [, int $length [, string $allowable_tags ]] )

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

handle

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

Length of the data to be retrieved.
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.
