对象的号码,我想按照这个模式来打印对象的数量打印:如何根据PHP
If there is 1 object, print 0
If there is 2 objects, print 0 1
If there is 3 objects, print 0 1 2
我尝试下面的代码:
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
哪我不能使用。我怎样才能做到这一点?
