ngx_var_get() and ngx_var_set() are for the nginx variables, nothing from PHP.

If in an nginx config, you call a variable that is NOT set before, you will always get a signal 11 error. With or without ngx-php.

everything is correct if I call a function with a non-existent variable in nginx i got crash with signal 11
UPD: if i try call NULL variable on nginx a got "nil", but in PHP i got crashed with signal 11

I'll add a test for null variables. And if needed a fix.

I check sources PHP ZEND on repository. I found only RETURN_NULL(); but i don't know why nginx got crash.

If you know how fix it? do it, please)
