The method of realizing the _php of the Gregorian calendar in PHP technique

Recently to the Gregorian calendar to get the corresponding festival of the algorithm is more interested in this, so I searched a circle on the Internet. Good, still be found a relatively good PHP class, the realization of the Gregorian calendar to convert to the lunar calendar (lunar calendar), the lunar calendar to convert the algorithm, but also to obtain the Ganzhi annals, Zodiac, and the corresponding lunar calendar in Chinese name, etc., the function is quite complete, here to share to everyone. The
Concrete class code is as follows:

  var $MAX _year=2100; var $lunarInfo =array (Array (0,2,9,21936), Array (6,1,30,9656), Array (0,2,17,9584), Array (0,2,6,21168), Array ( 5,1,26,43344), Array (0,2,13,59728), Array (0,2,2,27296), Array (3,1,22,44368), Array (0,2,10,43856), Array ( 8,1,30,19304), Array (0,2,19,19168), Array (0,2,8,42352), Array (5,1,29,21096), Array (0,2,16,53856), Array (0,2,4,55632 ), Array (4,1,25,27304), Array (0,2,13,22176), Array (0,2,2,39632), Array (2,1,22,19176), Array (0,2,10,19168), Array ( 6,1,30,42200), Array (0,2,18,42192), Array (0,2,6,53840), Array (5,1,26,54568), Array (0,2,14,46400), Array (0,2,3,54944 ), Array (2,1,23,38608), Array (0,2,11,38320), Array (7,2,1,18872), Array (0,2,20,18800), Array (0,2,8,42160), Array ( 5,1,28,45656), Array (0,2,16,27216), Array (0,2,5,27968), Array (4,1,24,44456), Array (0,2,13,11104), Array (0,2,2,38256 ), Array (2,1,23,18808), Array (0,2,10,18800), Array (6,1,30,25776), Array (0,2,17,54432), Array (0,2,6,59984), Array ( 5,1,26,27976), Array (0,2,14,23248), arrAy (0,2,4,11104), Array (3,1,24,37744), Array (0,2,11,37600), Array (7,1,31,51560), Array (0,2,19,51536), Array ( 0,2,8,54432), Array (6,1,27,55888), Array (0,2,15,46416), Array (0,2,5,22176), Array (4,1,25,43736), Array (0,2,13,9680) , Array (0,2,2,37584), Array (2,1,22,51544), Array (0,2,10,43344), Array (7,1,29,46248), Array (0,2,17,27808), Array ( 0,2,6,46416), Array (5,1,27,21928), Array (0,2,14,19872), Array (0,2,3,42416), Array (3,1,24,21176), Array (0,2,12,21168 ), Array (8,1,31,43344), Array (0,2,18,59728), Array (0,2,8,27296), Array (6,1,28,44368), Array (0,2,15,43856), Array ( 0,2,5,19296), Array (4,1,25,42352), Array (0,2,13,42352), Array (0,2,2,21088), Array (3,1,21,59696), Array (0,2,9,55632) , Array (7,1,30,23208), Array (0,2,17,22176), Array (0,2,6,38608), Array (5,1,27,19176), Array (0,2,15,19152), Array ( 0,2,3,42192), Array (4,1,23,53864), Array (0,2,11,53840), Array (8,1,31,54568), Array (0,2,18,46400), Array (0,2,7,46752 ), Array (6,1,28,38608), Array (0,2,16,38320), Array (0,2,5,18864), Array (4,1,25,42168), Array (0,2,13,42160), Array (10,2,2,45656), Array (0,2,20,27216), Array (0,2,9,27968), Array (6,1,29,44448), Array (0,2,17,43872), Array (0,2,6,38256), Array (5,1,27,18808), Array (0,2,15,18800), Array (0,2,4,25776), Array (3,1,23,27216), Array ( 0,2,10,59984), Array (8,1,31,27432), Array (0,2,19,23232), Array (0,2,7,43872), Array (5,1,28,37736), Array ( 0,2,16,37600), Array (0,2,5,51552), Array (4,1,24,54440), Array (0,2,12,54432), Array (0,2,1,55888), Array (2,1,22,23208 ), Array (0,2,9,22176), Array (7,1,29,43736), Array (0,2,18,9680), Array (0,2,7,37584), Array (5,1,26,51544), Array ( 0,2,14,43344), Array (0,2,3,46240), Array (4,1,23,46416), Array (0,2,10,44368), Array (9,1,31,21928), Array ( 0,2,19,19360), Array (0,2,8,42416), Array (6,1,28,21176), Array (0,2,16,21168), Array (0,2,5,43312), Array (4,1,25,29864 ), Array (0,2,12,27296), Array (0,2,1,44368), Array (2,1,22,19880), Array (0,2,10,19296), Array (6,1,29,42352), Array ( 0,2,17,42208), Array (0,2,6,53856), Array (5,1,26,59696), Array (0,2,13,54576), Array (0,2,3,23200), Array (3,1,23,27472), Array (0,2,11,38608), Array (11,1,31,19176), Array (0,2,19,19152), Array (0,2,8,42192), Array (6,1,28,53848), Array ( 0,2,15,53840), Array (0,2,4,54560), Array (5,1,24,55968), Array (0,2,12,46496), Array (0,2,1,22224), Array (2,1,22,19160 ), Array (0,2,10,18864), Array (7,1,30,42168), Array (0,2,17,42160), Array (0,2,6,43600), Array (5,1,26,46376), Array ( 0,2,14,27936), Array (0,2,2,44448), Array (3,1,23,21936), Array (0,2,11,37744), Array (8,2,1,18808), Array (0,2,19,18800 ), Array (0,2,8,25776), Array (6,1,28,27216), Array (0,2,15,59984), Array (0,2,4,27424), Array (4,1,24,43872), Array ( 0,2,12,43744), Array (0,2,2,37600), Array (3,1,21,51568), Array (0,2,9,51552), Array (7,1,29,54440), Array (0,2,17,54432 ), Array (0,2,5,55888), Array (5,1,26,23208), Array (0,2,14,22176), Array (0,2,3,42704), Array (4,1,23,21224), Array ( 0,2,11,21200), Array (8,1,31,43352), Array (0,2,19,43344), Array (0,2,7,46240), Array (6,1,27,46416), Array ( 0,2,15,44368), Array (0,2,5,21920), Array (4,1,24,42448), Array (0,2,12,42416), Array (0,2,2,21168), arrAy (3,1,22,43320), Array (0,2,9,26928), Array (7,1,29,29336), Array (0,2,17,27296), Array (0,2,6,44368), Array ( 5,1,26,19880), Array (0,2,14,19296), Array (0,2,3,42352), Array (4,1,24,21104), Array (0,2,10,53856), Array ( 8,1,30,59696), Array (0,2,18,54560), Array (0,2,7,55968), Array (6,1,27,27472), Array (0,2,15,22224), Array (0,2,5,19168
