Description:
------------
Hello,

PHP-CGI keeps crashing when loading configuration file with variable in <php.ini> file. Variable are declared as ENV ones.

It doesn't crash if the variable is undefined.

I Think this bug is related to this one already corrected but only for apache2 thing :  https://bugs.php.net/bug.php?id=49677
sapi_getenv (NO apache2) versus php_apache_sapi_getenv (apache2)

Test script:
---------------
Into php.ini file :

error_log = ${titi}


Expected result:
----------------
PHP should not crash.

Actual result:
--------------
(gdb) backtrace

I can't reproduce this:

nikic@pluto:~/dev$ cat php.ini
error_log = ${ERROR_LOG}
nikic@pluto:~/dev$ ERROR_LOG=foo php -c php.ini -i | grep error_log
error_log => foo => foo

Thank you for the report, and for helping us make PHP better.

actually, you should use a existed env variable name to trigger this bug.
