php - 用于检测以星号开头的行的正则表达式

Question

下面的代码无法检测到该事件的单个实例。 =O 怎么了？ =\

如何检测以下以星号开头的行(以换行符开头)？我不知所措。这与我预期的不同。

$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);

Answer 1

添加 m 修饰符以指定它具有多行主题，如 #^\*.*#m
