PHP create random tmp file and get its full path
提问by Farzher
After I do:
在我这样做之后：
$temp = tmpfile();
fwrite($temp, "writing to tempfile");
I'd like to get a full path to the $tempfile that tmpfilehas created.
我想获得已创建$temp文件的完整路径tmpfile。
What do I need to do to get that information?
我需要做什么才能获得这些信息？

tmpfilereturns a stream-able file pointer.
tmpfile返回一个可流式传输的文件指针。
To get the corresponding path, ask the stream for its meta data:
要获取相应的路径，请向流询问其元数据：
$file = tmpfile();
$path = stream_get_meta_data($file)['uri']; // eg: /tmp/phpFx0513a
The benefit of the tmpfileapproach? PHP automatically removes the $pathwhen $filegoes out of scope. With tempnam, you must manually remove the created file.
该tmpfile方法的好处？PHP 会自动删除$pathwhen$file超出范围。使用tempnam，您必须手动删除创建的文件。
