PHP array read out succession - php

Question

In PHP I have an Array like this:
$BulkArray[$i]
This Array is feed with plenty of Numbers (e.g. 1 => 100, 2 => 300, 3 => 100, and so on).
Now I want to find within the whole range of numbers, the greatest succession of a number equal or less than 500. I want to write the number of succession.
for example I have the array
1 => 100, 2 => 300, 3 => 100,
4 => 50, 5 => 50, 6 => 50, 7 => 50, 8 => 50,
9 => 500, 10 => 200, 11 => 100
as you can see, number 1,2 & 3 are together 500. So this is the first succession.
2,3,4,5 are also 500 together. (This succession(4) is bigger than the first succession(3))
And so on,then you will get the highest succession: 3,4,5,6,7,8 (succession with 6 numbers) which is 350 (but lower than 500m, as we searched for it)
Now, how can I write with the Array:
$BulkArray[$i], that the highest succession is 6 ?
Because 6 is the highest succession found in the whole array for 500!
(It's for categorizing specific Carparts)

The answer of User "fas M" here again, with little improvement:
<?php //lets call your $BulkArray = $values;
$values=array( 1 => 100, 2 => 300, 3 => 100,
4 => 50, 5 => 50, 6 => 50, 7 => 50, 8 => 50,
9 => 500, 10 => 200, 11 => 100 );
$sum=0; // to sum up until 500
$Vals500=array(); // array to store index with <= 500
$i=0; // index for new aaray that will store keys that made up <= 500
$key1=1; //value to iterate the array defined above
for($key=1; $key <= count($values); $key++){
$sum = $sum + $values[$key]; // get sum of values
if($sum <= 500){ $Vals500[$i][]=$key; } //append all key of sum ==500
if($sum >= 500) { $i++; $key=$key1++; $sum=0; } //check sum then reintialize
//added bigger equal
}
echo count(max($Vals500)); // read out the biggest succession
?>
Thanks again to fas M !

Click Here or here you can see somehing
<?php //lets call your $BulkArray = $values;
$values=array( 1 => 100, 2 => 300, 3 => 100,
4 => 50, 5 => 50, 6 => 50, 7 => 50, 8 => 50,
9 => 500, 10 => 200, 11 => 100 );
$sum=0; // to sum up until 500
$Vals500=array(); // array to store index with <= 500
$i=0; // index for new aaray that will store keys that made up <= 500
$key1=1; //value to iterate the array defined above
//print_r($values); echo '<br/>';
for($key=1; $key <= count($values); $key++){
$sum = $sum + $values[$key]; // get sum of values
if($sum <= 500){ $Vals500[$i][]=$key; } //append all key of sum ==500
if($sum == 500) { $i++; $key=$key1++; $sum=0; } //check sum then reinitialize values
}
foreach($Vals500 as $val){} //search for second array with many indeces in $Vals500. NB: i fail this place
echo print_r($Vals500);
print 'the highest succession found is '; print_r($Vals500[2]); //
?>
