此解决方案有效(无论 X 后面的数字是多少):
This solution works (no matter what the number after X is):
function myCustomAdd($string)
{
$original = $string;
$new = explode('_',$original);
$a = end($new);
$b = preg_replace("/[^0-9,.]/", "", $a);
$c = $b + 1;
$letters = preg_replace("/[^a-zA-Z,.]/", '', $a);
$d = $new[0].'_'.$new[1].'_'.$letters.$c;
return $d;
}
var_dump(myCustomAdd("20120815_00_X13"));
输出:
string(15) "20120815_00_X14"
