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
