fgetss — 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`.

### Changelog

Version | Description
--- | ---
5.0.0 | The `length` parameter is optional

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.
