Variable error in loop

I made no code corrections to the previous examples I posted.

They are just a variation of your own code examples that have been reformatted, and to which a HTML comment has been added to indicate where the missing </span> end-tags should be.

So you could take note and correct your own code.

As I (and others) have stated, without more detailed information about your project we aren’t able to determine where else in your project the value of $visited is being changed (to zero).
