PHP, Return everything to the left, strrchr() ?

Question

Hello!

The following code returns everything to right of the last occurrence of a dash:

$string1 = 'some-random-string-123456';
$string2 = strrchr($string1, '-');

echo $string2;

output: -123456

is there a function that will return everything to the left of the last dash? so the out put would be:

some-random-string

Thanks!

Answer 1

$string2 = substr($string1, 0, strrpos($string1, "-"))

Answer 2

Something like this will work..

$string2 = substr($string1, 0, strpos($string1, '-'));
