php入门学习知识点三 PHP上传
一、上传表单的HTML代码
复制代码 代码如下:
注意事项:1、action是上传的新
2、enctype这个属性要写成 “multipart/form-data”
二、PHP代码
复制代码 代码如下:
if(is_uploaded_file($_FILES["Imgs"]["tmp_name"])){
$phpupfile=$_FILES["Imgs"];
//输出上传文件的数组结构;
print_r($phpupfile);
//输出上传文件的各类信息
echo $phpupfile["size"]."
"; //文件名
echo $phpupfile["type"]."
"; //文件类型
echo $phpupfile["tmp_name"]."
"; //昨时文件名包含路径
echo $phpupfile["name"]."
"; //上传的文件名
/*
* 上传的错误信息
* 0 代表成功上传,
* 1,2 代表超过了设定的最大上传值
* 3 代表只有部分上传
* 4 代表没有文件被上传
* 5 代表上传文件大小为0
*/
echo $phpupfile["error"]."
";
//上传函数 (其时在提交表单后,已将上传的文件保存在服务器的临时文件夹内,这时需要将其移动到网站的指定文件夹内)
move_uploaded_file($phpupfile["tmp_name"],$phpupfile["name"]); //将上传的文件保存到指定的文件夹
/*
*以下部分是附加部分
*/
//判断文件是否存在 1代表存在,0代表未找到
echo 'This File is exists:'.file_exists($phpupfile["name"]).'
'; //查询文件或目录是否存在
//unlink 删除文件
echo '删除文件:'.unlink($phpupfile["name"]).';1 为删除成功,0为删除失败';
//mkdir 创建文件夹
if(file_exists('pic')==FALSE){
mkdir("pic");
}
if(file_exists('pic/ts')==FALSE){
mkdir("pic/ts");
}
//rmdir 删除文件夹
if(file_exists('pic/ts')==FALSE){
rmdir('pic/ts');
}
//rename 重命名
rename("guitar11-hp-sprite.png", "1.png");
echo "
";
echo 'This File is exists:'.file_exists($phpupfile["name"]).'
';
}
?>
注意点:1、$_FILES["Imgs"] 这个Imgs就是你HTML代码中所定义的控件名称
