How can I split a string at the first occurrence of - (minus sign) into two $vars with PHP?
如何使用 PHP 在第一次出现 -（减号）时将字符串拆分为两个 $vars？
I have found how to split on every "-" but, not only on the first occurrence.
我已经找到了如何在每个“-”上拆分，但不仅仅是在第一次出现时拆分。
example:
例子：
this - is - line - of whatever - is - relevant
$var1 = this
$var2 = is - line - of whatever - is - relevant
Note, also stripped the first "-" .
注意，还去掉了第一个 "-" 。
Thanks in advance for the help!
在此先感谢您的帮助！

It's very simple, using an extra paramater to explodethat many people don't realize is there:
这很简单，使用一个explode很多人没有意识到的额外参数：
list($before, $after) = explode('-', $source, 2);
list($before, $after) = explode('-', $source, 2);

$array = explode('-', 'some-string', 2);
Then you could do $var1=$array[0]and $var2=$array[1].
然后你可以做$var1=$array[0]和$var2=$array[1]。

Here is what you need: using list() with explode():
这是您需要的：使用 list() 和 expand()：
list($var1, $var2) = explode(' - ', 'this - is - line - of whatever - is - relevant', 2);
Note the spaces around the "-" (minus sign)
注意“-”（减号）周围的空格
