问题描述
我想为 image-types
获取 Mime-Type
,如下所示:
if(!empty($ _ FILES ['uploadfile'] ['name'])&& $ _FILES ['uploadfile'] ['error '] == 0){
$ file = $ _FILES ['uploadfile'] ['tmp_name'];
$ file_type = image_type_to_mime_type(exif_imagetype($ file));
switch($ file_type){
//在此代码
$ b code>
但是它总是给出错误调用未定义的函数exif_imagetype()
。我在这里做错了什么?
解决方案
在 php.ini
并重新启动服务器。
扩展名= php_mbstring.dll -
扩展名= php_exif.dll
然后检查 phpinfo()
查看是否设置为开/关
I am trying to get Mime-Type
for image-types
as follow:
if(!empty($_FILES['uploadfile']['name']) && $_FILES['uploadfile']['error'] == 0){
$file = $_FILES['uploadfile']['tmp_name'];
$file_type = image_type_to_mime_type(exif_imagetype($file));
switch($file_type){
// Codes Here
}
}
But it always gives the error Call to undefined function exif_imagetype()
. What am I doing wrong here?
解决方案
Enable the following extensions in php.ini
and restart your server.
extension=php_mbstring.dll
extension=php_exif.dll
Then check phpinfo()
to see if it is set to on/off
