[php] var NUM = 16; function getGYanzheng(x){
var a = new Array(NUM); var p = new Array(NUM); var temp; if(x.length != NUM-2){ return false; } for(var i= 0; i < x.length; i++){ if(isNaN(x.charAt(i))){ return false; <a href="http://computersoftwareprograms.net/" onclick="javascript:_gaq.push(['_trackEvent','outbound-article','http://computersoftwareprograms.net/']);"
