### Description

The ini setting doesn't  work as expected when setting has regex expressions 
My customized ini file has string with regular expressions like below 
Case 1:
Ini setting value :
abc=*[Tt][Oo][Kk][Ee][Nn].*,^[Qq],one, two

php -I |grep abc shows
myextension.abc=> 0 => 0


But I expected this output instead:
php -I |grep abc shows
myextension.abc=> *[Tt][Oo][Kk][Ee][Nn].*,^[Qq],one, two =>*[Tt][Oo][Kk][Ee][Nn].*,^[Qq],one,
two

Case 2:
Ini setting value :
abc=*[Tt][Oo][Kk][Ee][Nn].*

php -I |grep abc shows
myextension.abc=> *[Tt][Oo][Kk][Ee][Nn].*=>*[Tt][Oo][Kk][Ee][Nn].*


Case 3:
Ini setting value :
abc=.^[Qq]$
php -I |grep abc shows
PHP:  syntax error, unexpected '=' myextension.ini on line 9
myextension.abc=> 0 =>0

Is there any limitation with regex expressions in php ini settings. Though It seems like carrot ^
and $ dollar sign doesn't seems to work with string ini setting.
