在PHP中捕获两组方括号之间的文本

Question

I need some way of capturing the text between two group of square brackets. So for example, the following string:

test test [foo] bar [/foo] test

I need to output "bar", but 'bar' is a variable word

How can I get the output I need?

Answer 1

Maybe with this simply expression:

preg_match('/\](.*)\[/', 'test test [foo] bar [/foo] test', $match);
echo trim($match[1]);
