fgetss — Gets line from file pointer and strip HTML tags
Syntax:
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.
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.
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.
