I have just uploaded the next version of the Portable UTF-8, PHP unicode library. This version adds 9 UTF-8 string functions to the library. There are a few bug fixes, and also some performance optimizations, but the release was mainly to extend the functionality of the library.
You can download the new version here and the detailed explanations of all functions is available here.
utf8_string– Makes a string from UTF-8 code points.
utf8_substr_count– Count the number of sub string occurrences. Replacement for
is_ascii– Checks if a string is 7 bit ASCII.
utf8_range– Returns an array of characters between two codepoints (int or hex) or UTF8 characters. Replacement for
utf8_hash– Generates a hash/string of random UTF-8 characters.
utf8_chr_map– Applies callback to all UTF-8 characters.
utf8_access– Provides a way to access individual UTF-8 characters. Replacement for
utf8_str_sort– Sort ascending/descending with respect to codepoints of all characters.
utf8_strip_tags– Replacement for PHP’s
Optimizations & Improvements:
utf8_bomnow in-lines the BOM string instead of creating the string using
packand caching it as a
utf8_chrnow accepts hexadecimal codepoints.
utf8_splithas been improved. New version uses PCRE and is better and faster.
utf8_substr– improved consistency with
extension_loadedwas misspelled as
extension_lodedin v 1.1 Line 50 – reported by Goran Jurić.
