Re: Re: replace nested custom html tags

Hello, a bit off topic here but for those using html_entities that would like to display back the string as html, here is: function unhtmlentities( $stringHtml ) { $tmp = get_html_translation_table( HTML_ENTITIES ); $tmp = array_flip ( $tmp ); $stringTmp = strtr ( $stringHtml, $tmp ); return $stringTmp; } it seems to work fine, but I did'nt use it enough to judge yet... py ----- Original Message ----- From: "Bruce BrackBill" <brackbillbruce@hotmail.com> To: <elias_bachaalany@yahoo.com>; <php-general@lists.php.net> Sent: Monday, November 05, 2001 5:25 AM Subject: [PHP] Re: replace nested custom html tags > > Thanks for your response.
