Hello,

I have a sentence like this.

1 $nbsp;     2     3   4

As you see, in between 1 2 and 3 text, there are extra spaces. I want the output with only one space between them. so my output will be 1 2 3 4

How can i use php trim to get the output like this. If i use trim, it can only remove whitespace, but not that  

Thanks.
