PHP Manual: 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. The function retains the parsing state from call to call, and as such is not equivalent to calling strip_tags on the return value of fgets.

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. See strip_tags for details regarding allowable_tags.

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.

Examples

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.
