Question

What are the supported file types in php file upload?

   Choose a file to upload: <input name="uploadedfile" type="file" />
   <br />
      Username:<input type="text" name="username">
   <br />
      Password:<input type="text" name="password">
   <br />
      FaxNumber:<input type="text" name="faxnumber">

   <input type="submit" value="Upload File" />

Answer 1

购买力平价并不限制类似的情况。档案永远只是数据。 PHP向您提供,当数据“被贴出”(或上载)到服务器时。它确实只是说,“这一数据是上载的,这里是通往临时档案的道路”。只要你的服务器能够处理整个档案的接收,所有材料都可以接受。您是否希望限制能够上载的种类,完全由您负责。

Answer 2

There is no limit client side, all files/types are supported. PHP, also, has no built in limits and supports all files. If you want to limit what can be uploaded in php it looks something like the following snippet, Which limits the file to a gif image:

if ($_FILES["file"]["type"] == "image/gif"){
    //do stuff here
}
else{
    //the file was wrong type handle error here
}

You can find a list of MIME types, "image/gif" in the above code, at:

档案类型不因缺省而受到限制,除非你具体规定限制。

有效载荷档案类型:

$_FILES[ yourFileName ][ type ]

Answer 4

by default: nearly anything you want (pdf,txt,exe,jpg) etc.

Its your job to filter out anything you do wish to use. you can filter against anything inside $_FILES array(type,size) etc

Answer 5

PHP will support all file types for file upload, But you have to validate for some file extensions which can hack your site and also you have to consider file size to avoid long running script.

Answer 6

PHP没有上载。有效载荷由http://europa-eu-un.org提供,由您的网络服务(Apache、IIS等)处理。

不管怎样,如果你想要节省上载的档案,那么所有档案类型都应进行罚款。如果你想把上载的档案作为投入处理,那么事情就会更加美发。

Answer 7

您可以上载任何档案,而Sphp确实没有限制。你自己需要做限制。

关于客户档案格式限制,请参阅时使用许可证档案格式”。

<input type="file" accept="image/*" /> <!-- all image types --> 
<input type="file" accept="audio/*" /> <!-- all audio types -->

对于服务器,您可以按此对上载文档进行过滤。

if(in_array(mime_type($file_path),$allowed_mime_types)){
    // save the file
}

$allowed_mime_types = array(
         image/jpeg ,
         image/jpg ,
         image/png ,
         image/gif ,
         video/mp4 
);


/*

function mime_type($file_path)
{
    if (function_exists( finfo_open )) {            
        $finfo = new finfo(FILEINFO_MIME_TYPE, null);
        $mime_type = $finfo->file($file_path);

            ob_end_clean();
            $mime_type = null;
        }
        $type = trim(ob_get_clean());
