preg_match expression for extracting everything but "[]"

Question

<some string>[]<somestring>

example

variable[]_abc

How can I get everything except [] from the string using preg_ in php?

Answer 1

If you only want to remove [] use str_replace.

$newstring = str_replace('[]', '' $string);

There is no need for a regex to remove static characters.

Answer 2

preg_replace('/\[\]/','',$string);
