| 1.20.x bootstrap.inc | check_plain($text) |
Encodes special characters in a plain-text string for display as HTML.
Also validates strings as UTF-8 to prevent cross site scripting attacks on Internet Explorer 6.
Parameters
string $text: The text to be checked or processed.
Return value
string: An HTML safe version of $text. If $text is not valid UTF-8, an empty string is returned and, on PHP < 5.4, a warning may be issued depending on server configuration (see https://bugs.php.net/bug.php?id=47494).
