This repository is unofficial and experimental. Its goal is to extend current implementation of PHP/intl extension with some +/- essential, or at least useful, missing functions.

• ini settings added (only used by utf8_[starts|ends]with for now):
  • intl.turkic_casefolding: i (U+69) = I (U+49) vs i (U+69) = İ (U+130) + ı (U+131) = I (U+49)
• extra stuffs:
  • all matches are "grapheme consistent"
  • expose Unicode version supported by intl/ICU (phpinfo + constant INTL_UNICODE_VERSION)
• Collator, methods added (+ procedural equivalents):
  • replace (str_ireplace replacement) string Collator::replace(string $string, string $search, string $replacement [, int &count ])
  • lfind (str(i)str replacement) mixed Collator::lfind(string $haystack, string $needle [, int $startOffset = 0 [, bool $before ]])
  • rfind (strr(i)str replacement with a different behavior) mixed Collator::rfind(string $haystack, string $needle [, int $startOffset = 0 [, bool $before ]])
  • lindex (str(i)pos replacement) int Collator::lindex(string $haystack, string $needle [, int $startOffset = 0 ])
  • rindex (strr(i)pos replacement with a different behavior) int Collator::rindex(string $haystack, string $needle [, int $startOffset = 0 ])
  • startswith (locale dependant) boolean Collator::startswith(string $haystack, string $needle)
  • endswith (locale dependant) boolean Collator::endswith(string $haystack, string $needle)
• Regexp, class added (+ procedural equivalents):
  • __construct Regexp::__construct(string $pattern [, mixed $flags ])
  • match int Regexp::match(string $subject, array &$match [, int $startOffset = 0 [, int $flags = 0 ]])
  • matchAll int Regexp::matchAll(string $subject, array &$match [, int $startOffset = 0 [, int $flags = 0 ]])
  • replace string Regexp::replace(string $subject, string $replacement [, int $limit = -1 [, int &$count ]])
  • replaceCallback string Regexp::replaceCallback(string $subject, callable $replacement [, int $limit = -1 [, int &$count ]])
  • split array Regexp::split(string $subject [, int $limit = -1 [, int $flags = 0 ]])
• String, functions added:
  • full case mapping: functions utf8_to[upper|lower|title] (strtoupper, strtolower, ucwords replacements) string utf8_toupper(string $string [, string $locale = ini_get('intl.default_locale') ])
  • utf8_startswith (locale independant and turkic languages supported) bool utf8_startswith(string $string, string $prefix [, bool $case_insensitive = FALSE ])
  • utf8_endswith (locale independant and turkic languages supported) bool utf8_endswith(string $string, string $suffix [, bool $case_insensitive = FALSE ])

Note: for locale independant case insensitivity (turkic languages excluded), you can use UCA rules by creating a "root" Collator ($coll = new Collator('root');) (do not use an empty string as locale name) and a secondary-level strength ($coll->setStrength(Collator::SECONDARY);)

1. make sure your current PHP installation does not already include intl as a static extension (if dynamic, backup/move first intl.so or php_intl.dll somewhere else)
2. grab these sources
3. compile and install them as any other extension: cd path/to/sources && phpize && ./configure && make && make install
4. load it by adding extension=intl.so (replace intl.so by php_intl.dll on Windows) to your php.ini
5. restart your web server if relevant (depends on the SAPI - needed for fpm or apache2handler)

1. get PHP sources, uncompress them and go into their directory
2. move or delete official sources of intl (rm -fr ext/intl/*)
3. grab these sources and extract them into the directory ext/intl
4. run buildconf from top directory of PHP (./buildconf --force)
5. compile PHP as usual (./configure ... --enable-intl && make && make install)
