我想根据这种模式打印对象的数量:
If there is 1 object, print 0
If there is 2 objects, print 0 1
If there is 3 objects, print 0 1 2
我尝试了以下代码:
for($i = count($nodes) ; $i >= 0 ; $i--){
print $i;
}
但结果是:
If there is 1 object, print 0 1
If there is 2 objects, print 0 1 2
if there is 3 objects, print 0 1 2 3
我不能使用。我怎样才能做到这一点?
