如何檢查上傳的文件是視頻，並可確保真正的視頻類型

Question

所選文件不是與擴展AVI，MP4等記事本文件

我嘗試這樣做：

$file_allowed = array('gif','png' ,'jpg','avi','mp4','wmv','mov','flv','webm','ogv','mp3','m4a','ogg','oga'); 

$uploaded_filename = $_FILES['attachment']['name']; 

$file_ext = pathinfo($uploaded_filename, PATHINFO_EXTENSION); 

if(!in_array($file_ext,$file_allowed)) 
{  
    exit; 
} 

Answer 1

試試這個變量進行驗證

$_FILES["attachment"]["type"]; 

Answer 2

嘗試改變你這樣的代碼：

$file_allowed = array('gif','png' ,'jpg','avi','mp4','wmv','mov','flv','webm','ogv','mp3','m4a','ogg','oga'); 

$uploaded_filename = $_FILES["attachment"]["type"]; 

$file_ext = pathinfo($uploaded_filename, PATHINFO_EXTENSION); 

if(!in_array($file_ext,$file_allowed)) { 
exit; 

}
