PHP fgetss() Function: Read a Line from a File and Strip HTML/PHP Tags
This article explains the PHP fgetss() function, its signature, parameter details, return behavior, and provides a complete example that reads a file while removing HTML and PHP tags, demonstrating the output and usage nuances.
The fgetss() function reads a line from a file pointer and automatically strips out any HTML and PHP tags, behaving similarly to fgets() but with tag removal.
Signature:
string fgetss(resource $handle[, int $length[, string $allowable_tags]])Parameters:
handle : a valid file pointer opened by fopen() or fsockopen() and not yet closed.
length (optional): the maximum number of bytes to read.
allowable_tags (optional): a string of tags that should not be stripped.
Return value: the read string with HTML/PHP tags removed, or FALSE on error.
Example usage:
<?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);
}
?>Output produced by the script:
Welcome! Today is the of .
