The simplest way is just to loop over the values, adding the current array value to the previous output value to create the new output value. You can then convert that into an array of [x => y] values using array_combine:
$arr=array(1100,3150,4430,4430,5170,7450,7450,7450,8230);
$out = array($arr[0]);
for ($i = 1; $i < count($arr); $i++)
$out[$i] = $out[$i-1] + $arr[$i];
$arr = array_combine($out, $arr);
print_r($arr);
Output:
Array (
[1100] => 1100
[4250] => 3150
[8680] => 4430
[13110] => 4430
[18280] => 5170
[25730] => 7450
[33180] => 7450
[40630] => 7450
[48860] => 8230
)

@TanayAcan judging by your code, you probably just need$arr = array_combine($out, $arr);. That will give you an array that looks like[1100 => 1100, 4250 => 3150, 8680 => 4430 ...]

to get that one array into 2 arrays of graph co-ordinates, you can do this:
$x = array();
$y = array();
$running_total = 0;
for($i = 0; $i < count($arr); $i++)
$y[$i] = $arr[$i];
$running_total += $arr[$i];
$x[$i] = $running_total;
This will give you two arrays; array $x that contains a list of your X-coordinates, and $y, that gives you a list of your Y-coordinates; and you will still have access to your original $arr array, should you need to do further calculations on it. Based on your question, I think that will get you what you need.
However, if you are saying you want 1 array where the X co-ordinates are the array indexes, and the value is the array value itself, for example $y[3150] = 4250, then that is impossible; because you have duplicates in your original list, you cannot use those values as array indexes without ending up overwriting them.
(At least, not without making each array value an array itself, but that is taking things an order of magnitude above where is probably necessary)

@TanayAcan judging by your code, you probably just need$arr = array_combine($out, $arr);. That will give you an array that looks like[1100 => 1100, 4250 => 3150, 8680 => 4430 ...]

I did array_combine but my array became "1100":1100,"3150":4250,"4430":13110,"5170":18280,"7450":40630,"8230":48860 it skipped repeated numbers but I need them, what can I do ?

The simplest way is just to loop over the values, adding the current array value to the previous output value to create the new output value. You can then convert that into an array of [x => y] values using array_combine:
$arr=array(1100,3150,4430,4430,5170,7450,7450,7450,8230);
$out = array($arr[0]);
for ($i = 1; $i < count($arr); $i++)
$out[$i] = $out[$i-1] + $arr[$i];
$arr = array_combine($out, $arr);
print_r($arr);
Output:
Array (
[1100] => 1100
[4250] => 3150
[8680] => 4430
[13110] => 4430
[18280] => 5170
[25730] => 7450
[33180] => 7450
[40630] => 7450
[48860] => 8230
)

ohh I was doing $arr[$i]+$arr[$i-1]... that was my mistake. Thanks Nick but I have one more question. Now I have 2 arrays, can I show them in same graph ? ($arr is y-axis and $out is x-axis)

to get that one array into 2 arrays of graph co-ordinates, you can do this:
$x = array();
$y = array();
$running_total = 0;
for($i = 0; $i < count($arr); $i++)
$y[$i] = $arr[$i];
$running_total += $arr[$i];
$x[$i] = $running_total;
This will give you two arrays; array $x that contains a list of your X-coordinates, and $y, that gives you a list of your Y-coordinates; and you will still have access to your original $arr array, should you need to do further calculations on it. Based on your question, I think that will get you what you need.
However, if you are saying you want 1 array where the X co-ordinates are the array indexes, and the value is the array value itself, for example $y[3150] = 4250, then that is impossible; because you have duplicates in your original list, you cannot use those values as array indexes without ending up overwriting them.
(At least, not without making each array value an array itself, but that is taking things an order of magnitude above where is probably necessary)
