The realization of the method of English word single plural conversion in the program

Here is the implementation of PHP, in fact, in CSharp or Java, the implementation of the same approach.

/** * Wirror:pluralize A String * @param $string/function pluralize ($string) {$plural = Array ('/(Quiz) $/i ', "$1zes"), Array ('/^ (ox) $/i ', "$1en"), Array ('/([m|l]) ouse$/i ', "$1ice"), Array ('/(Matr|vert|ind) ix|ex$/i ', "$1ices" ), Array ('/(X|CH|SS|SH) $/i ', ' $1es '), Array ('/([^aeiouy]|qu) y$/i ', ' $1ies '), Array ('/([^aeiouy]|qu) ies$/i ', ' $1y '), Array ('/(hive) $/i ', "$1s"), Array ('/(?:( [^f]) fe| ([LR] f) $/i ', "$1$2ves"), Array ('/sis$/i ', "ses"), Array ('/[[Ti]] um$/i ', "$1a"), Array ('/(Buffal|tomat) o$/i ', "$1oes "), Array (' bu) s$/i '," $1ses "), Array ('/(alias|status) $/i ', ' $1es '), Array (' Octop|vir ' us$/i ', ' $1i '), Array ('/( ax|test) is$/i ', "$1es"), Array ('/s$/i ', "s"), Array ('/$/', "s")); $singular = Array (Array ("/s$/", ""), Array ("/(n) ews$/", "$1ews"), Array ("[Ti]) a$/", "$1um"), Array ("/((a) naly| ( b) a| (d) iagno| (p) arenthe| (p) rogno| (s) ynop| (t) He) ses$/"," $1$2sis "), Array ("/(^analy) ses$/"," $1sis "), Array (" [^f]) ves$/"," $1fe "), Array ("/(Hive) s$/","$"), Array ("/(tive) s$/", "$"), Array ("/[[LR]) ves$/", "$1f"), Array ("/[^aeiouy]|qu) ies$/", "$1y"), Array ("/(s) eries$/"," $1eries "), Array ("/(m) ovies$/"," $1ovie "), Array ("/(X|CH|SS|SH) es$/"," $ "), Array (" [M|l]) ice$/"," $ 1ouse "), Array ("/(BUS) es$/"," $ "), Array ("/(O) es$/"," $ "), Array ("/(shoe) s$/"," $ "), Array ("/(Cris|ax|test) es$/"," $1is "), Array ("/[[Octop|vir]) i$/"," $1us "), Array ("/(Alias|status) es$/"," $ "), Array ("/^ (ox) en/"," $ "), Array ("/( Vert|ind) ices$/"," $1ex "), Array ("/(MATR) ices$/"," $1ix "), Array ("/(Quiz) zes$/"," $ "); $irregular = Array (' Move ', ' moves '), array (' sex ', ' sexes '), array (' child ', ' children '), Array (' Mans ', ' Men ') , array (' person ', ' people ')); $uncountable = Array (' sheep ', ' Fish ', ' series ', ' species ', ' money ', ' rice ', ' information ', ' equipment '); Save some time in the "case" singular and plural are the same if (In_array ($string), $uncountable) return $string; Check for irregular singular forms foreach ($iRregular as $noun) {if (Strtolower ($string) = = $noun [0]) return $noun [1];}//Check for matches using regular Expre Ssions foreach ($plural as $pattern) {if (Preg_match ($pattern [0], $string)) return preg_replace ($pattern [0], $patt ERN[1], $string); return $string; }
