transliteration - Where can I find a list of IDs or rules for the PHP transliterator (Intl)? -

transliterator::listids() list ids, apparently it's not complete list.

in example page, id looks like:

any-latin; nfd; [:nonspacing mark:] remove; nfc; [:punctuation:] remove; lower(); 

which kind of weird, because ids supposed unique. looks more rule, doesn't work if pass createfromrules method :)

anyway, i'm trying remove punctuation string, except dash (-), or characters specific list.

do know if that's possible? or there documentation better explains syntax transliterator ?

the ids transliterator::listids() "basic ids". example gave "compound id". can see icu docs on this.

you can create own rules transliterator::createfromrules().

you can take @ prefefined rules (replace 48 icu version):

<?php $a = new resourcebundle(null, 'icudt48l-translit', true);  foreach ($a['rulebasedtransliteratorids'] $name => $v) {     $file = @$v['file'];     if (!$file) {         $file = $v['internal'];         echo $name, " (direction $file[direction]; internal)\n";     } else {          echo $name, " (direction: $file[direction])\n";         echo $file['resource'];     }     echo "\n--------------\n"; } 

after formatting, result looks this.
