I have following array
Array (
[0] => 1995,17500
[1] => 2052,17500
[2] => 2052,17500
[3] => 2236,30000
[4] => 2235,15000
[5] => 2235,40000
);
I have exploded the value with comma ,.
foreach($array as $key=>$value) {
$newar = explode(',', $value);
}
So I have similar first value ie $newar["0"]. For example 2235 and 2052. And I would like to have sum of second value ie $newar["1"].
How can I achieve following result with PHP.
Array (
[0] => 1995, 17500
[1] => 2052, 35000
[2] => 2036, 30000
[3] => 2235, 55000
)
You can create a new array key/index based and use array_key_exists
to check if the key already exists. If so sum the value, if not create the key. This is not the exact result you want, but it's neater.
$newar = []; //New Array
foreach($array as $value) {
$explArr = explode(',', $value);
if(array_key_exists($explArr[0], $newar)){ //Check if the key already exists
$newar[$explArr[0]] += $explArr[1]; //Sum value to existing key
} else {
$newar[$explArr[0]] = $explArr[1]; //Create key
}
}
Your result array will look like this:
Array (
[1995] => 17500
[2052] => 35000
[2036] => 30000
[2235] => 55000
)
