$file = file("new.txt"); What happens to the lines that are blank.

I know that an element is created for them but what are they. The reason I ask is I've tried to do an array_keys (find all keys that have the value "")

But it says that it can't find any blank elements. Of course I noticed that the array_keys says it uses an "array input", this might be a manually made array.

not new to programming just the terminology. Not schooled.

I want to remove all blank elements from the array. maybe I should start with the txt file I opened.

Rare data looks like

Hi
how are you

Notbad

and you

not actually data but I want to remove the blank line between "how are you" and "not bad" but I don't know where these lines are they are different everytime.

The lines aren't blank, they have the carriage return still in them. If you search for lines of one character length you should get them, unless they have CR/LF pairs, in which case they should have both in them.

Or you can look for elements that are equal to "\n" for blank lines.

Thanks, I think it worked.

How would I simply remove the elements. I now know there index number.

The reason is I'm dealing with huge files with lots of these empty \n and I was hoping that removing these would speed up my parsing time.

But if I spend to long parsing these files for the \n, might not be faster.

Anyways, I'll eventually find out.
