Explode datalist into array

Question

I've got a list of data with in the following format:

data\n
data\n
data\n
data\n
data\n

Now I try to explode it into an array with

$array = explode("\n", $dataList);

What happens next is that there is a key with no data, I think it is because of the \n on the end.

Is there a way to explode it so that the last key isn't set?

Thanks!

Not directly. You can either:

Remove the trailing "\n" with trim.
Remove the last element of $array with array_pop.
Use preg_split instead with the flag PREG_SPLIT_NO_EMPTY.

Yea, I like the trim method, that would probably be better then the array_pop. Nice call there.

Remove empty values by:

$array = array_filter( $array );

That will also remove entries with "0".

After you explode, use array_pop() to pop the last item:

$array = explode("\n", $dataList);

array_pop($array);

You can add an if statement using count() and empty() if you want to check if the last item contains something other than a linebreak character, but that should get you what you need.
