fgetss
(PHP 4, PHP 5)
fgetss — Gets line from file pointer and strip HTML tags
Description
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.
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.
