PHP and Python implement Project Euler questions 1 and 2

I started learning python recently, so I used Project Euler to practice

Problem 1

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

Run result: 233168

PHP version:

/**
 * @desc Project Euler 1
 * @Author tina
 * @Date 2015-08-27
 */
$sum = 0;
for($i=0; $i<1000; $i++){
    if(($i%3 == 0) || ($i%5 == 0)){
        $sum += $i;
    }
}
echo $sum;

python version:

sum = 0
for i in range(1000):
    if((i%3 == 0) or (i%5 == 0)):
        sum += i
print sum

Problem 2

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values ​​do not exceed four million, find the sum of the even-valued terms.

Run result: 4613732

PHP version:

/**
 * @desc : Project Euler 2
 * @Author : tina 
 * @Date : 2015-08-27
 */
$fab1 = 1;
$fab2 = 1;
$sum = 0;
do{
    $fab = $fab1+$fab2;
    $fab1 = $fab2;
    $fab2 = $fab;
    if($fab%2 == 0){
        $sum += $fab;
    }
}while($fab < 4000000);
echo $sum;

Python version:

fab1 = 1
fab2 = 1
sum = 0
while True :
    fab = fab1+fab2
    fab1 = fab2
    fab2 = fab
    if(fab%2 == 0):
        sum += fab
    if(fab > 4000000) : break
print sum

In fact, it feels generally the same... But after reading some python introductions, I feel that the functions are very powerful. Lists, dictionaries, and set data types can actually handle complex numbers! ! Looking forward to it! (PS: It seems that the great man who invented Python was born in mathematics, no wonder Luo!)
