fgetss

(PHP 4, PHP 5, PHP 7)

Gets line from file pointer and strip HTML tags

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.

Returns:

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.

Notes:

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.

Examples:

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.
