how to do a sum on a string in php?
arrays, php, string, sum
Solution
$sum = array_sum( explode( ',', $v ) );
What this does is split `$v` by the delimiter `,` with `explode()` and sum the resulting array of parts with `array_sum()`.
Problem
i have a simple question: i have this var: `$v = "24000,1500,1500,1500,1500,1500,";` i would like to add those numbers together. i've tried to `str_replace` the `,` with `+` and so a `eval()`, but that didn't worked. i also tried `str_split()` but it doesn't know to split on the `,`. maybe if somehow convert it to an array and do a `array_sum`... any ideas? thanks
