| isASCII($str) X-Ref |
| Checks if a string contains 7bit ASCII only return: bool param: string $str author: Andreas Haerter <andreas.haerter@dev.mail-node.com> |
| isUtf8($str) X-Ref |
| Tries to detect if a string is in Unicode encoding return: bool param: string $str author: <bmorel@ssi.fr> link: http://php.net/manual/en/function.utf8-encode.php |
| strip($str) X-Ref |
| Strips all high byte chars Returns a pure ASCII7 string return: string param: string $str author: Andreas Gohr <andi@splitbrain.org> |
| stripspecials($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) 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) author: Andreas Gohr <andi@splitbrain.org> |

| correctIdx($str, $i, $next = false) X-Ref |
| adjust a byte index into a utf8 string to a utf8 character boundary return: int byte index into $str now pointing to a utf8 character boundary param: string $str utf8 character string param: int $i byte index into $str param: bool $next direction to search for boundary, false = up (current character) true = down (next character) author: chris smith <chris@jalakai.co.uk> |
