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

[myersboar]

The following code returns everything to right of the last occurrence of a dash:\[code\]$string1 = 'some-random-string-123456';$string2 = strrchr($string1, '-');echo $string2;output: -123456\[/code\]is there a function that will return everything to the left of the last dash? so the out put would be:\[code\]some-random-string\[/code\]Thanks!
