    I'm not sure what you mean?

    You can use the popen() handler to run a process on the server where the PHP is installed, but whether it will do it depends on what the access rights of the httpd/apache process are.

    You can also use system() to run a program/command on the server (with the same limitation mentioned by seamus)...

    ... The last part of your question about "...just downloading it..." is confusing - can you provide more info?

    If you call an application in the Web root that has exec rights, then it will execute rather than be downloaded, regardless of the scripting technology.

    If you mean can PHP force a client to execute an application on their own machine, then no - it can't.
