From: Operating system: CentOS 4.4 PHP version: 5.4.0RC6 Package: *General Issues Bug Type: Bug Bug description:htmlentities() behaves differently and thus breaks existing code
Description: ------------ //This code must be run via web: //This is a string from e.g. some database containing a german umlaut 'ä'. Note the encoding really is iso8859-1 . It's just assigned here literally to be concise. $a = "Rechnungsadresse ändern"; //this output works: (An empty string activates some autodetection) var_dump(htmlentities($a, ENT_COMPAT | ENT_HTML401, '')); //this works too (the same output is generated): var_dump(htmlentities($a, ENT_COMPAT | ENT_HTML401, 'ISO-8859-1')); //this does NOT work (outputs empty string) var_dump(htmlentities($a)); // Reason: php changed the charset htmlentities uses when you NOT give anything (90% of the code out there): //determine_charset() : /////////////////////////////////////////////////////// // php-5.2.1/ext/standard/html.c : // /* Guarantee default behaviour for backwards compatibility */ // if (charset_hint == NULL) // return cs_8859_1; ///////////////////////////////////////////////////// // php-5.4.0RC4/ext/standard/html.c : // /* Default is now UTF-8 */ // if (charset_hint == NULL) // return cs_utf_8; // This breaks the meaning of existing german code. For example, typo3 outputs empty string if end users used german umlauts in rich text editor in backend. // Please change determine_charset() back to using cs_8859_1 if the third parameter of htmlentities() is omitted.
