Matthew Weier O'Phinney has posted the third article in his "Deploying Zend Server Tips" series today. In this tip he talks about file permissions and execution of shell commands.

In the first tip, I detailed writing deployment scripts. One of the snippets I shared was a chmod routine. [...] The code is fine; what I did not share is where in the deployment script you should invoke it. As I discovered from experience, this is key.

He points out that the deployment is run under a different user than the web server user. Future writes to those files by the web server could fail because of it, so he recommends running the permission change as the last step of the deployment script. If this ti was interesting and you'd like to check out more, you can find them in the first and second parts of the series.

On her blog Nessa has a brief look at working with permissions with PHP via three functions - chown, chgrp and chmod.

PHP uses the same command as *nix systems when dealing with changing permissions for files. These commands are particularly useful in situations where PHP runs as a different user on the system, which is common when PHP is compiled as an Apache user.

She includes a basic syntax for each of them and how one (chmod) could be used in an example of file creation.
