php - 正则表达式，用于检测以星号开头的行

下面的代码无法检测到该事件的单个实例。出什么事了？=
如何检测以下以星号开头的行（以换行开头）？我不知所措。这可不像我想象的那样。

$text ="Nothing here to detect...though it is the first line.
* '' [[test]]
* Another line that starts with an asterisk
** yet another...though it has two...but who cares about the 2nd one?";


$t = preg_match_all('#^\*.*#', $text, $match);
echo "found=".$t."\n";
print_r($match);

最佳答案

添加m修饰符以指定它具有多行主题，如#^\*.*#m
