这是我的上传表格：
<form action="uploads.PHP" method="post" enctype="multipart/form-data"> <input name="fileupload" type="file" multiple> <button>Upload</button> </form>
我的最大上传大小设置如下：
; Maximum allowed size for uploaded files. upload_max_filesize = 5M ; Must be greater than or equal to upload_max_filesize post_max_size = 5M
如果我上传的文件大于5M,则var_dump($_ FILES)为空.我能做到：
if($_FILES){
echo "Upload done!";
}
如果文件大于5M,则不设置$_FILES.但这有点奇怪.你会怎么做？
编辑：
文件的var_dump超过5M：
array(0) {
}
var_dump文件< = 5M：
array(1) {
["fileupload"]=>
array(5) {
["name"]=>
string(13) "netzerk12.pdf"
["type"]=>
string(15) "application/pdf"
["tmp_name"]=>
string(22) "/tmp/uploads/PHPWhm8M0"
["error"]=>
int(0)
["size"]=>
int(352361)
}
}
你可以查看$_SERVER [‘CONTENT_LENGTH’]：
// check that post_max_size has not been reached
// convert_to_bytes is the function turn `5M` to bytes because $_SERVER['CONTENT_LENGTH'] is in bytes.
if (isset($_SERVER['CONTENT_LENGTH'])
&& (int) $_SERVER['CONTENT_LENGTH'] > convert_to_bytes(ini_get('post_max_size')))
{
// ... with your logic
throw new Exception('File too large!');
}
