如何解决是否有可用于PHP的文件描述脚本的文件扩展名？
| 我正在寻找的东西将采用为其赋予的任何文件扩展名，并返回对该扩展名的描述。 例如 ：$extension = \'PNG\';
$description = ext_description($extension);
echo $description // Outputs \'Portable Network Graphic\'
$extension = \'DOC\';
$description = ext_description($extension);
echo $description // Outputs \'Microsoft Office Word Document\'
解决方法
是的，有一个，是getID3库，在fileinfo库中有PHP版本。
由于每个人的描述都不一样，因此您可以创建一个对数组数据起作用的简单查找函数。您只需要将文件类型添加到数组中就可以了：
function ext_description($extension) {
static extensions = array(
\'png\' => \'Portable Network Graphic\',\'doc\' => \'Microsoft Office Word Document\'
);
$extension = strtolower($extension);
return isset($extensions[$extension])
? $extensions[$extension]
: sprintf(\'Unknown File (%s)\',$extension)
;
}
function ext_description($extension) {
switch ($extension) {
case \"png\":
return \"Portable Network Graphic\";
case \"doc\":
return \"Microsoft Office Word Document\";
default:
return \"Unknow extention\";
}
