使用substr到我的场景或更好的功能可用

Question

How can I get only the first values until "-"

Like for example: I have a string,

$title = "9283-returns-to-normal-in-1989";
or
$title = "83-returns-to-normal-in-1989";
or
$title = "9283231-returns-to-normal-in-1989";

I wanted to only get the first numerical values in that string until "-". So that, I can only get 9283, 83 or 9283231 no matter how many values in it.

Please help

Try this:

strstr($title, '-', true);
