PHP preg_replace不能用于多行

Question

I am trying to remove the "-" character at the end of every line:

$text = "abc - xyz

abc-

-xyz
";

It is not producing the desired result as of now.

I am using the following PHP:

$text = preg_replace("/\-$/m", "*", $text);

The desired result:

$text = "abc - xyz

abc*

-xyz
";

or a similar solution.

Answer 1

$text = "abc - xyz

abc-

-xyz


123-

---s---

--sss
";


$text = preg_replace("/\-$/m", "", $text);

echo $text;

Yields

abc - xyz

abc

-xyz


123

---s--

--sss
