PHP图片上传功能

form method=”post” action=”” enctype=”multipart/form-data”

input type=”file” name=”upFile” id=”upFile” /

/form

$file_name=$_FILES[‘upFile’][‘name’]; //上传文件名

$file_type=$_FILES[‘upFile’][‘type’]; //上传文件类型

$file_tame=$_FILES[‘upFile’][‘tmp_name’]; //上传文件的临时文件名

$file_size=$_FILES[‘upFile’][‘size’]; //上传文件的大小

move_uploaded_file($_FILES[“file”][“tmp_name”],”../你的存放上传文件的路径/”); //移动上传文件

php怎样上传图片

一下代码可以实现简单的（单个的）文件上传，你看看吧：有更好的方法可以讨论

?php

////////上传文件////////////

if(isset($_POST[“sub”])){

//$upfile=”../upload_file/”.$_FILES[“file”][“name”];

$name=time();//定义变量，保存图片名，以防图片的名字相同

echo $name;

$name.=strrchr($_FILES[“file”][“name”],”.”);//上传文件的名称

echo $name;

$num=rand(1,10);

$type=$_FILES[“file”][“type”];

$size=$_FILES[“file”][“size”];

$tmp_name=$_FILES[“file”][“tmp_name”];

if($_FILES[“fiel”][“error”]0){

echo “上传文件有误:”.$_FILES[“file”][“error”].”br/”;

}else{

echo “上传文件名为：”.$name.”br”;

echo “上传文件类型为：”.$type.”br”;

echo “上传文件大小为：”.($size/1024).”br”;

echo “上传到：”.$tmp_name.”br”;

if(file_exists(“../upload_file/$name”)){

echo “已经存在”;

}else{

if(move_uploaded_file($tmp_name,”../upload_file/$name”)){

echo $name.”上传成功”;

}else{

echo $name.”上传失败”;

}

form method=”post” action=”php_upload.php” enctype=”multipart/form-data”

input type=”file” name=”file”

input type=”submit” name=”sub” value=”upload”

input type=”reset” name=”res” value=”reset”/

/form

php上传图片

这个需要控件，单纯的php无法实现异步上传.

你可以试下这个
