在特定位置包含1或0的集合中搜索二进制数

Question

I have an array of strings (zeros and ones) in a format similar to the following:

[01100101],[10010000],[00000001]...and so on (all the same length, there's about 30 entries)

I'd like to be able to search these numbers using a search similar to "0xxxx01". The search, in this case, would return the first and third string.

What would be the best way to go about doing this? I'm in the middle of learning PHP, an answer in that format would be preferred.

Answer 1

Building on top of the answer posted by @George Lund (you need to use . instead of X):

$arr = array('01100101','10010000','00000001');

$result = preg_grep("/0.....01/", $arr);

print_r($result);
