Does this variable actually exist anywhere, or is it just sitting in some file?

What do you need to be able to do with this variable?

Shell variables only make sense in a shell...

You could export the variable, then have your PHP executed like this:

Code:
# variable file

export A="asdf"

Code:
#!/bin/sh

. variablefile

/usr/lib/php5.3/bin/php <<EOF
<?php
        printf("variable A is %s\n", getenv("A")); ?>
EOF

exit

But I get the feeling you want to have more control over the variable than that, you need to set and retrieve it when you please, not just when first executed, and do so in a manner safe across several connections.

This is the sort of thing they usually use a database with. The combination of Linux, Apache, Mysql and PHP is so common they usually call it LAMP...
