That is not a solution to the problem as you previously stated it:

But there is some other Way to populate an array by using space,comma(s),dot(s) by default.

like ...

j=abc def ghi jkl mno pqrs tuv wxyz<br>
j=abc,def,ghi,jkl,mno,pqrs,tuv,wxyz<br>
j=abc.def.ghi.jkl.mno.pqrs.tuv.wxyz<br>

I need this way of Obtaining he values in an array.

And here:

I cant get the space separated value. I need a way to get the j= abc def ghi jkl mno pqrs tuv wxyz in a single line of code using a method of Config::IniFiles.

Changing the requirements (by changing the input) is unfair to those trying to help.
