使用preg_split避免空键值

Question

I would like to know if there is a way to avoid empty keys in an Array while using preg_split.

The problem is that I have an input field in that every input will be split by spaces. In that case there even will be created a new Array key.

So i use:

$search_term = preg_split('/[\s]+/', $search_term);

when I will enter abc it creates an Array with:

[0] => abc

but when I will enter:

abc ...

it creates an Array like:

[0] => abc
[1] => 

it`s like it will be prepared for the value. But I would like to know if I can unset this key until it gets some value.

Thanks alot.

Answer 1

ye...

preg_split('/[\s]+/', $search_term, -1, PREG_SPLIT_NO_EMPTY);

probably best to check the documentation before asking these kind of questions though.
