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.

  • @TimBiegeleisen, array_sum would be faster than explode and adding value, isn't it ? So I wanna know, can I do array_sum in my case.

    How big is your data set? If it isn't very big, there will most likely not be any noticeable performance differences.

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));
