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
