Python vs PHP bubble Sorting and summation sum calculation performance test

test Environment: Processor i5-3230m,64 bit Ubuntu 14.04
Python 2.7.6, php 5.4.39, PHP 7.0.0-dev (2015/04/21)

Test content:
Bubble sort: Sorts 10 ascending numbers, outputs in descending order, and loops 1 million times.
Cumulative sum: 0+1+2+3+...+99999999

Bubble Sort Test results comparison:
Program: Python PHP5 PHP7
Time: 16.910s 14.715s 8.011s
Memory: 35.8m 9.0m 12.5m

Comparison of cumulative summation test results:
Program: Python PHP5 PHP7
Time: 10.057s 3.855s 1.855s
Memory: 3.039g8.9m 12.5m
python memory consumption up to 3GB, what is the situation?

Conclusion:
Both Python and PHP are dynamic scripting languages, and there is no JIT mechanism, so testing is fair.
Python computing performance is not as good as PHP5, with PHP7 gap is bigger, so the future will not black PHP calculation is not as good as python.

The following is a detailed test procedure:

python bubble sort:
def bubble_sort (LST):
length = Len (LST)
For I in range (0, length, 1):
For j in range (0, length-1, 1):
If LST[J] < lst[j+1]:
temp = Lst[j]
LST[J] = lst[j+1]
LST[J+1] = Temp
return LST
For C in range (1000000):
LST = [0,1,2,3,4,5,6,7,8,9]
LST = Bubble_sort (LST)
Print (LST)
Test: Time Python bubblesort.py

Python summation:
sum = 0
For I in Range (100000000):
sum + = i
Print (sum)
Test: Time Python sum.py
Time: 0m10.057s
Memory: 3.039g



php Bubble Sort:
function Bubble_sort ($array) {
$size = count ($array);
for ($i =0; $i < $size; $i + +) {
for ($j =0; $j < $size-1; $j + +) {
if ($array [$j] < $array [$j +1]) {
$temp = $array [$j];
$array [$j] = $array [$j +1];
$array [$j +1] = $temp;
}
}
}
return $array;
}
for ($c =0; $c <1000000; $c + +) {
$array = Array (0,1,2,3,4,5,6,7,8,9);
$array = Bubble_sort ($array);
}
Print_r ($array);
