If you edit a php file in windows, upload and run it on linux with command line method. You may encounter a running problem probably like that:
[root@ItsCloud02 wsdl]# ./lnxcli.php
Extension './lnxcli.php' not present.
Or you may encounter some other strange problem.
Care the enter key. In windows environment, enter key generate two binary characters '0D0A'. But in Linux, enter key generate just only a 'OA'.
I wish it can help someone if you are using windows to code php and run it as a command line program on linux.
