How can I split a string at the first occurrence of "-" (minus sign) into two $vars with PHP?

Question

How can I split a string at the first occurrence of - (minus sign) into two $vars with PHP?

I have found how to split on every "-" but, not only on the first occurrence.

example:

this - is - line - of whatever - is - relevant
$var1 = this
$var2 = is - line - of whatever - is - relevant

Note, also stripped the first "-" .

Thanks in advance for the help!

Answer 1

$array=explode("-", "some-string", 1);

Then you could do $var1=$array[0] and $var2=$array[1].

Answer 2

It's very simple, using an extra paramater to explode that many people don't realize is there:

list($before, $after) = explode('-', $source, 2);
