哪里有好一点的php无组件上传代码？

Question

php的一大特点就是本身支持upload，并无“组件”一说。

Answer 1

哈哈。copy函数呀。你自己去看看就知道了。

Answer 2

move_uploaded_file($HTTP_POST_FILES['表单file对象名'], "目标文件名");
move_uploaded_file($_FILES['表单file对象名'], "目标文件名");
copy($HTTP_POST_FILES['表单file对象名'], "目标文件名");
copy($_FILES['表单file对象名'], "目标文件名");并无优劣之分，个人喜好罢了

Answer 3

//上传图片
//userfile 为上传时文件选择框的name$up_img_path="../upload/littlelm/";$tmp_name = $HTTP_POST_FILES["userfile"]["tmp_name"];if(!empty($tmp_name))
