这是表格
form action="index.php" method="POST" enctype="multipart/form-data" >
<input type="file" name="image[]" multiple="multiple">
<input type="submit" value="upload">
</form>
我只是尝试只运行我的代码时,if(!empty($_FILES['image'])){但由于某种原因,在提交没有文件并且只点击提交时数组不为空.
如果有帮助的话,这是代码的其余部分,谢谢.

$count = $count +1;
if(count($_FILES['image']['tmp_name']) > 5){ …我是C++的新手,我试图让用户继续将双打输入数组,当用户输入-1时程序停止.我的代码有效,但当12个项目添加到数组时,我得到以下错误:

中止(核心倾倒)
这是我的代码:
int main(){
int size=5;
int i=0;
double *numbers = new double[size];
cout<<"Enter your double:"<<endl;
while(1){
double *numbers2=new double[size];
cin>>numbers[i];
if(i>=size-1){
size=size*2;
memcpy(&numbers2, &numbers, size);
delete[]numbers;
numbers=numbers2;
}
if(numbers[i]==-1){
break;
}
cout<<numbers[i];
i++;
}
}
