C++ C++ to PHP

[fasjaweasc]

Hi! Can someone translate this code from c++ to php?

#include <cstdio>
#include <algorithm>

#define REP(a,n) for (int a=0; a<(n); ++a)

using namespace std;

#define INF 1000000000

typedef long long LL;

///////////////////////////

#define MAXN 1000000

int wagi[MAXN];
int orig[MAXN]; 
int perm[MAXN]; 
bool vis[MAXN]; 

int minw = INF;

int main()
{
    int N;
    scanf("%d", &N);
    REP(a, N)
    {
        scanf("%d", &wagi[a]);
        minw = min(minw, wagi[a]);
    }
    REP(a, N)
    {
        scanf("%d", &orig[a]);
        --orig[a];
    }
    REP(a, N)
    {
        int nr;
        scanf("%d", &nr);
        --nr;
        perm[nr] = orig[a];
    }
    LL wynik = 0;
    REP(pocz, N)
        if (!vis[pocz])
        {
            int minc = INF; 
            LL suma = 0; 
            int cur = pocz;
            int dl = 0; 
            for (;;)
            {
                minc = min(minc, wagi[cur]);
                suma += wagi[cur];
                cur = perm[cur];
                vis[cur] = true;
                ++dl;
                if (cur==pocz)
                    break;
            }
            wynik += min(suma+(dl-2)*(LL)minc, suma+minc+(dl+1)*(LL)minw);
        }
    printf("%Ld\n", wynik);
}
