Debugging php message window style
From Director Online Wiki
Most php debugging can be done simply using browser. But there are times when this is awkward (i.e. when building custom http headers). Here's a way to 'put' data to a consol window while your php executes (requires a *nix environment):
SSH to your php directory and enter the following:
mkfifo -m 772 .debug tail -f .debug
Now in your php scripts direct debug messages to the debug FIFO with:
exec("echo \"Some debug statement or $var\" > .debug");
or use a text file for output:
exec("echo \"Some debug statement or $var\" >> debug.txt");
When the php executes, you can watch the output in your SSH session. (NOTE: Make sure you're tailing your fifo when the php runs otherwise it'll hang while php waits for you to read the output or just use a text file as mentioned.)
