| isASCII($str) X-Ref |
| Checks if a string contains 7bit ASCII only author: Andreas Haerter <andreas.haerter@dev.mail-node.com> return: bool param: string $str |
| isUtf8($str) X-Ref |
| Tries to detect if a string is in Unicode encoding author: <bmorel@ssi.fr> return: bool link: http://php.net/manual/en/function.utf8-encode.php param: string $str |
| strip($str) X-Ref |
| Strips all high byte chars Returns a pure ASCII7 string author: Andreas Gohr <andi@splitbrain.org> return: string param: string $str |
| stripspecials($string, $repl = '', $additional = '') X-Ref |
| Removes special characters (nonalphanumeric) from a UTF-8 string This function adds the controlchars 0x00 to 0x19 to the array of stripped chars (they are not included in $UTF8_SPECIAL_CHARS) author: Andreas Gohr <andi@splitbrain.org> return: string param: string $string The UTF8 string to strip of special chars param: string $repl Replace special with this string param: string $additional Additional chars to strip (used in regexp char class) |
