Copy the code The code is as follows:
$text = '

If(end($tags) == '' ) array_pop($tags);
}
foreach($tags as $tag) {
if ($stripContent)
[^>]*>|)';
$str = preg_replace('#]*>'.$content.'#is', '', $str);
}
return $str;
}
$str = 'red text';
$tags = 'font';
$a = strip_only($str, $tags); // red text
$b = strip_only($str, $tags, true); // text
?>
