正则表达式匹配以%%开头和结尾的字符串

Question

I have a text that has multiple occurrences of variables in this format:

Example text will %%include%% these %%parameters%%

I'm trying to use this:

preg_match('/%%[\\s\\S]*?%%/i',$output, $matches);

But for some reason I'm getting only the first match, any ideas?

使用preg_match_all因为您需要多个匹配项。
