正則表達式，用於檢測以星號開頭的行

Question

下面的代碼無法檢測出現的單個實例。 = O什么錯了？ = \\

如何檢測以星號開頭的以下行（以換行符開頭）？ 我不知所措。 這不符合我的預期。

$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修飾符以指定它具有多行主題，如#^\\*.*#m
