PHP Question
can't get the logic to restart looping
I have 15 databases 1,2,3,4, ... 15
and I have the variable $i default at 1 and each time the $i count gets to 3, $i restarts the looping from 1 again until 3 and it will stop until value from database is done counting.
$detailPsycho = mysql_query("SELECT * FROM `psycho` WHERE `flag` = 2 ") or die(mysql_error());
while($detail = mysql_fetch_array($detailPsycho)){
for($i = 1;$i<=3;$i++){
echo $detail['sequence']."&".$i." <br>";
}
}
and run over like this :/
1&1
1&2
1&3
2&1
2&2
2&3

You try to do a loop (for{}) in a loop (while{}) which is a complicated way of doing something trivial. This is the "while+for" result :
$detailPsycho = mysql_query("SELECT * FROM `psycho` WHERE `flag` = 2 ") or die(mysql_error());
i = (int) 1;
while($detail = mysql_fetch_array($detailPsycho)) {
echo $detail['sequence']."&".$i." <br>";
$i++;
if ($i > 3) $i = 1;
}
