Remove everything before (including special character) in array

Is it possible to remove everything before special characters including this character in array ?

For example, SUBSTR() function is used in string

$a= ('1-160');
echo substr($a,strpos($a,'-')+1);
//output is 160

Any function for array like SUBSTR()? (least priority to preg_replace).

Here array is structured as following example, every index consists int value + hyphen(-)

$a= array('1-160','2-250', '3-380');

I need to change removing every values before hyphen and hyphen also

$a= array('160','250', '380');

Actually my requirement is to sum all values after the hyphen(-) in array. If hyphen(-) can be removed, it can be done as 

echo array_sum($a);
//output is 790

but, because of the special characters, I am generating output as following way. 

$total = 0;
foreach($a AS $val){
  $b = explode('-',$val);
  $total += $b[1];
}
echo $total;
//output is 790

I am searching short and fast method as possible.

Although you already have the answer, this is for your reference. 

array_sum(array_map(function ($item) {return explode('-', $item)[1];}, $a));

strstr with substr should work just fine

<?php

$a = ['1-160','2-250', '3-380'];
$result = [];

foreach($a as $b) {
    $result[] = substr(strstr($b, '-'), 1); // strstr => get content after needle inclusive needle, substr => remove needle
}

var_dump($result);

var_dump(array_sum($result));
