Coding php for windows to upload to Linux

[LarryK]

I'm trying to remember what code I had that would work on a Linux server but not on my apache php mysql install on a Windows machine.

Does anyone know of instances of this? Someone I know doesn't believe that this is the case because they believe that php is truly cross platform. I realize that for most code it does work on Windows and Linux but I think there are exceptions that need to be noted.

Thanks in advance.

it was probably chmod(), which sets the user permissions on files on the local machine. Because Windows NTFS permissions override anything that php would set, the file permisisons are ignored in commands such as mkdir() and I believe you can't do chmod()--I never tried chmod on an IIS box, because I just set permissions through the OS....

If it's not that, then I don't know

If you're running on different OSs, that implies you are running different builds of PHP. They may not be built with identical options. See phpinfo() for more details.

Also there are some extensions / features at the moment which only work on Linux / Windows. These are clearly marked as such in the documentation (and are relatively few). These aren't normally required.

Inherent differences are things like filename case sensitivity and filesystem conventions; these are also documented in the appropriate sections of the manual.

In any case, developing on one platform and deploying on another isn't a terribly good thing to do- you may encounter problems. I recommend that you at least get a Linux test server and run as close to an identical build as possible.

Also, if your production server DOES have a different build, it may be desirable to create a test environment on your production server (different Apache virtual host or something) that you can use to test new builds of your application prior to deployment.

That puts light on this otherwise difficult to see subject. I appreciate your response, it will no doubt help me with my deployments before there are problems.
