Say you have this numeric variable that can be set by the user but you never want it to leave a certain range when it gets printed. How could you use parameter expansion such that it will never expand outside of that boundary? Thanks

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. SEE ALSO
