today I learned this:

PHP код:

for (new i = 0; i != 10; i++)
    for (new j = 0; j != 100; j++)
        Function(i, j); 


is faster then:

PHP код:

for (new j = 0; j != 100; j++)
    for (new i = 0; i != 10; i++)
        Function(i, j); 


because the inner loop always jumps 10*100 times, but the outer loop jumps different time. top code so jumps 10+10*100 times, bottom code so jumps 100+100*10 times. the less loop should be outer loop.
