Note: this simple solution works mostly when using codeigniter framework
注意：这个简单的解决方案主要在使用 codeigniter 框架时有效
$config['upload_path'] = './uploads/;
$config['allowed_types'] = 'pdf,doc,docx';
$config['max_size'] = 0;
$config['max_width'] = 0;
$config['max_height'] = 0;
$config['file_name'] = round(100,99); //make your file name random
$this->load->library('upload', $config);
$this->upload->initialize($config);
if($this->upload->do_upload('file_name')){
print $this->upload->data();
}else{
print $this->upload->display_errors();
}

There are already some question about the same topic. I will post answer again, I guess...
已经有一些关于同一主题的问题。我会再次发布答案，我猜...
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $_FILES['file']['TMP_NAME']);
switch ($mime) {
case 'image/jpeg':
case 'application/pdf':
case etc....:
default:
die("Unknown/not permitted file type");
}
