• PHP Regular Expression: string from inside brackets 3 answers

My string:

fields[name_1]

I want to get fields and name_1 using regex.

I'm know about preg_match_all(), but I'm not friends with regular expressions.

Answer 1

This can be used for direct match:

$string = 'fields[name_1]';

preg_match('/(.+)\[(.+)\]/', $string, $matches);

print_r($matches);

You get:

Array
(
    [0] => fields[name_1]
    [1] => fields
    [2] => name_1
)

So, $matches[1] and $matches[2] are what you needed.

Still I am unclear about your exact need!
