18位不重复订单号/**<br>
* 生成10位绝不重复订单号<br>
*/<br>
function order_number(){<br>
static $ORDERSN=array(); //静态变量<br>
$ors=date('ymd').substr(time(),-5).substr(microtime(),2,5); //生成16位数字基本号<br>
if (isset($ORDERSN[$ors])) { //判断是否有基本订单号<br>
$ORDERSN[$ors]++; //如果存在,将值自增1<br>
}else{<br>
$ORDERSN[$ors]=1;<br>
}<br>
return $ors.str_pad($ORDERSN[$ors],2,'0',STR_PAD_LEFT); //链接字符串<br>
}暂时只测试了本地，如果需要多并发，可以考虑将静态变量变为静态缓存判断
