Separte parts of a string

I am working on script to deal with strings, and I need it to take strings such as what you see below, and separate it out as seen below that.

$string_A = "some-random-text-t9958302"
$string_B = "unimportant-text-f100394"
$string_C = "nothing-here-matters-at-all-m4954433"

I am trying to pull the portion after the last - out of it, and separate it.

$string_A[0] = "t"
$string_A[1] = "9958302"

$string_B[0] = "f"
$string_B[1] = "100394"

$string_C[0] = "m"
$string_C[1] = "4954433"

For some reason this last left me stumped...

Any Ideas?

 

$string_A = "some-random-text-t9958302"
$explode_array = explode('-',$string_A);
$last_element = end($explode);
$string_array_a[0] = substr($last_element,0);
$string_array_a[1] = substr($last_element, 1);


That should do it.
I mean thats the basic logic to use - just massage it a bit to suite your needs

 

Many thanks, I just adapted it what I am using it for and it works perfectly!

 

Another approach:

preg_match('/-([a-z])(\d+)$/', $string_A, $matches);
$array_shift($matches);
$string_A = $matches;
