I would like to get this result:
0 1
1 1
2 1
3 1
...
19 1
0 2
1 2
2 2
3 2
...
19 2
...
0 10
1 10
2 10
3 10
...
19 10
but i don't know what i'm doing wrong, using this code:
$p=0;
for($i=0; $i<40; $i++)
{
if($i%20 == 0)
{
$p+=1;
$i=0;
} else {
echo $i.' '.$p;
echo '<br>';
}
}
When i try to run the code, it takes forever. What am i doing wrong? Please help me. Thanks.
You should use nested for loops
for($i = 1; $i <= 10; $i++) {
for($j = 0; $j < 20; $j++)
echo $j . ' ' . $i . '<br>';
echo '<br>';
}
