I *think* what you're asking, is as follows:

1. You have a plugin which uses an external shell command to debug PHP
2. This external shell command busy-waits 5 seconds
3. Because of (2), Vim also is stuck waiting for the command to finish for those 5 seconds.
4. You want Vim to do something during the wait period, but Vim is stuck waiting for the external command to finish.

As I see it then, there are a couple ways to do this:

Method 1:
1. Edit your refresh_browser.sh script to first wait 1-2 seconds before taking action.
2. Call your refresh_browser.sh script BEFORE your plugin, but as a background task (using something like :!sh refresh_browser.sh & on unix or :!start sh refresh_browser.sh on Windows)

Method 2:
1. Edit the plugin to call the command that waits as a background task instead of a foreground one.
2. Edit the command that currently waits to call back into Vim when complete with the results. See http://vim.wikia.com/wiki/Execute_external_programs_asynchronously_under_Windows

Let us know in detail what you actually mean if I'm off-base here. I have no idea what else "not possible to write commands in the command line" might mean.
