PHP中保留术语“句柄”吗？ [关闭]

Question

In my php code, I am writing a class to create log files, and therefore have to work with files. I would like to store the variable $handle as a field, however when I refer to it as $this->handle, "handle" changes color, to indicate that perhaps it is a reserved term.

I looked through the php manual as well as some other online sources and haven't found anywhere saying it is actually reserved. Can someone clear this up for me?

Thanks for your help.

Cheers!

------------- Edit ---------------

It looks like it's recognizing handle as at least 3 static methods...still not sure what the "K" word means. Key?

Not only is it not reserved, but it is a common convention to call resource IDs and more $handle. In fact, you can find it throughout the PHP documentation. For example, fopen.
