| UTF-8 aware alternative to strrpos |
| utf8_strrpos($str, $needle, $offset = null) X-Ref |
| UTF-8 aware alternative to strrpos |
| utf8_strpos($str, $needle, $offset = null) X-Ref |
| UTF-8 aware alternative to strpos |
| utf8_strtolower($str) X-Ref |
| UTF-8 aware alternative to strtolower |
| utf8_strtoupper($str) X-Ref |
| UTF-8 aware alternative to strtoupper |
| utf8_substr($str, $offset, $length = null) X-Ref |
| UTF-8 aware alternative to substr |
| utf8_strlen($text) X-Ref |
| Return the length (in characters) of a UTF-8 string |
| utf8_strrpos($str, $needle, $offset = null) X-Ref |
| UTF-8 aware alternative to strrpos Find position of last occurrence of a char in a string author: Harry Fuecks param: string $str haystack param: string $needle needle param: integer $offset (optional) offset (from left) return: mixed integer position or FALSE on failure |
| utf8_strpos($str, $needle, $offset = null) X-Ref |
| UTF-8 aware alternative to strpos Find position of first occurrence of a string author: Harry Fuecks param: string $str haystack param: string $needle needle param: integer $offset offset in characters (from left) return: mixed integer position or FALSE on failure |
| utf8_strtolower($string) X-Ref |
| UTF-8 aware alternative to strtolower Make a string lowercase Note: The concept of a characters "case" only exists is some alphabets such as Latin, Greek, Cyrillic, Armenian and archaic Georgian - it does not exist in the Chinese alphabet, for example. See Unicode Standard Annex #21: Case Mappings param: string return: string string in lowercase |
| utf8_strtoupper($string) X-Ref |
| UTF-8 aware alternative to strtoupper Make a string uppercase Note: The concept of a characters "case" only exists is some alphabets such as Latin, Greek, Cyrillic, Armenian and archaic Georgian - it does not exist in the Chinese alphabet, for example. See Unicode Standard Annex #21: Case Mappings param: string return: string string in uppercase |
| utf8_substr($str, $offset, $length = NULL) X-Ref |
| UTF-8 aware alternative to substr Return part of a string given character offset (and optionally length) Note arguments: comparied to substr - if offset or length are not integers, this version will not complain but rather massages them into an integer. Note on returned values: substr documentation states false can be returned in some cases (e.g. offset > string length) mb_substr never returns false, it will return an empty string instead. This adopts the mb_substr approach Note on implementation: PCRE only supports repetitions of less than 65536, in order to accept up to MAXINT values for offset and length, we'll repeat a group of 65535 characters when needed. Note on implementation: calculating the number of characters in the string is a relatively expensive operation, so we only carry it out when necessary. It isn't necessary for +ve offsets and no specified length author: Chris Smith<chris@jalakai.co.uk> param: string $str param: integer $offset number of UTF-8 characters offset (from left) param: integer $length (optional) length in UTF-8 characters from offset return: mixed string or FALSE if failure |
| utf8_strlen($text) X-Ref |
| Return the length (in characters) of a UTF-8 string param: string $text UTF-8 string return: integer Length (in chars) of given string |
| utf8_str_split($str, $split_len = 1) X-Ref |
| UTF-8 aware alternative to str_split Convert a string to an array author: Harry Fuecks param: string $str UTF-8 encoded param: int $split_len number to characters to split string by return: array characters in string reverses |
| utf8_strspn($str, $mask, $start = null, $length = null) X-Ref |
| UTF-8 aware alternative to strspn Find length of initial segment matching the mask author: Harry Fuecks |
| utf8_ucfirst($str) X-Ref |
| UTF-8 aware alternative to ucfirst Make a string's first character uppercase author: Harry Fuecks param: string return: string with first character as upper case (if applicable) |
| utf8_recode($string, $encoding) X-Ref |
| Recode a string to UTF-8 If the encoding is not supported, the string is returned as-is param: string $string Original string param: string $encoding Original encoding (lowered) return: string The string, encoded in UTF-8 |
| utf8_encode_ncr($text) X-Ref |
| Replace all UTF-8 chars that are not in ASCII with their NCR param: string $text UTF-8 string in NFC return: string ASCII string using NCRs for non-ASCII chars |
| utf8_encode_ncr_callback($m) X-Ref |
| Callback used in encode_ncr() Takes a UTF-8 char and replaces it with its NCR. Attention, $m is an array param: array $m 0-based numerically indexed array passed by preg_replace_callback() return: string A HTML NCR if the character is valid, or the original string otherwise |
| utf8_ord($chr) X-Ref |
| Converts a UTF-8 char to an NCR param: string $chr UTF-8 char return: integer UNICODE code point |
| utf8_chr($cp) X-Ref |
| Converts an NCR to a UTF-8 char param: int $cp UNICODE code point return: string UTF-8 char |
| utf8_decode_ncr($text) X-Ref |
| Convert Numeric Character References to UTF-8 chars Notes: - we do not convert NCRs recursively, if you pass &#38; it will return & - we DO NOT check for the existence of the Unicode characters, therefore an entity may be converted to an inexistent codepoint param: string $text String to convert, encoded in UTF-8 (no normal form required) return: string UTF-8 string where NCRs have been replaced with the actual chars |
| utf8_decode_ncr_callback($m) X-Ref |
| Callback used in decode_ncr() Takes a NCR (in decimal or hexadecimal) and returns a UTF-8 char. Attention, $m is an array. It will ignore most of invalid NCRs, but not all! param: array $m 0-based numerically indexed array passed by preg_replace_callback() return: string UTF-8 char |
| utf8_case_fold($text, $option = 'full') X-Ref |
| Case folds a unicode string as per Unicode 5.0, section 3.13 param: string $text text to be case folded param: string $option determines how we will fold the cases return: string case folded text |
| utf8_case_fold_nfkc($text, $option = 'full') X-Ref |
| Takes the input and does a "special" case fold. It does minor normalization and returns NFKC compatable text param: string $text text to be case folded param: string $option determines how we will fold the cases return: string case folded text |
| utf8_case_fold_nfc($text, $option = 'full') X-Ref |
| Assume the input is NFC: Takes the input and does a "special" case fold. It does minor normalization as well. param: string $text text to be case folded param: string $option determines how we will fold the cases return: string case folded text |
| utf8_normalize_nfc($strings) X-Ref |
| A wrapper function for the normalizer which takes care of including the class if required and modifies the passed strings to be in NFC (Normalization Form Composition). param: mixed $strings a string or an array of strings to normalize return: mixed the normalized content, preserving array keys if array given. |
| utf8_clean_string($text) X-Ref |
| This function is used to generate a "clean" version of a string. Clean means that it is a case insensitive form (case folding) and that it is normalized (NFC). Additionally a homographs of one character are transformed into one specific character (preferably ASCII if it is an ASCII character). Please be aware that if you change something within this function or within functions used here you need to rebuild/update the username_clean column in the users table. And all other columns that store a clean string otherwise you will break this functionality. param: string $text An unclean string, mabye user input (has to be valid UTF-8!) return: string Cleaned up version of the input string |
| utf8_htmlspecialchars($value) X-Ref |
| A wrapper for htmlspecialchars($value, ENT_COMPAT, 'UTF-8') |
| utf8_convert_message($message) X-Ref |
| Trying to convert returned system message to utf8 PHP assumes such messages are ISO-8859-1 so we'll do that too and if it breaks messages we'll blame it on them ;-) |
| utf8_wordwrap($string, $width = 75, $break = "\n", $cut = false) X-Ref |
| UTF8-compatible wordwrap replacement param: string $string The input string param: int $width The column width. Defaults to 75. param: string $break The line is broken using the optional break parameter. Defaults to '\n'. param: bool $cut If the cut is set to TRUE, the string is always wrapped at the specified width. So if you have a word that is larger than the given width, it is broken apart. return: string the given string wrapped at the specified column. |
| utf8_basename($filename) X-Ref |
| UTF8-safe basename() function basename() has some limitations and is dependent on the locale setting according to the PHP manual. Therefore we provide our own locale independant basename function. param: string $filename The filename basename() should be applied to return: string The basenamed filename |
| utf8_str_replace($search, $replace, $subject) X-Ref |
| UTF8-safe str_replace() function param: string $search The value to search for param: string $replace The replacement string param: string $subject The target string return: string The resultant string |
