用于获取php中字符串中[]之间内容的正则表达式

Question

I need to output the strings between []. For example I need this-echo, nobody to be displayed. But I am get this as result: [this-echo] Hello Everybody [nobody].

$txt = 'Hello World [this-echo] Hello Everybody [nobody]';
$regExp = '/\[([^)]+)\]/';
$match = preg_match("/\[(.*)\]/s", $txt, $output);

Answer 1

Try this

preg_match_all('/\[(.*?)\]/', $txt, $out);
print_r($out[1]);

get

Array ( [0] => this-echo [1] => nobody )

Answer 2

Instead of excluding the closing square bracket, you have excluded the closing round bracket in your character class: [^)] That is why the pattern doesn't stop at the first closing square bracket and reach the last of the string.

You only need to replace it with [^]] and to use preg_match_all to get several results.
