- The following example shows what is implemented: <?php $orig = $strings = array( 'côte', 'cote', 'côté', 'coté', 'fluÃe', 'flüÃe', ); echo "German phonebook:\n"; $c = collator_create( "de@collation=phonebook" ); foreach($c->sort($strings) as $string) { echo $string, "\n"; } echo $c->getAttribute(Collator::FRENCH_COLLATION) == Collator::ON ? "With" : "Without", " french accent sorting order\n"; echo "\nFrench with options:\n"; $c = collator_create( "fr" ); $c->setAttribute(Collator::CASE_FIRST, Collator::UPPER_FIRST); $c->setAttribute(Collator::CASE_LEVEL, Collator::ON); $c->setStrength(Collator::SECONDARY); foreach($c->sort($strings) as $string) { echo $string, "\n"; } echo $c->getAttribute(Collator::FRENCH_COLLATION) == Collator::ON ? "With" : "Without", " french accent sorting order\n"; ?>
