Php/mysql Array Help Need

Solution 1:

You mean while($j<$i) there.

Remember, you incremented $i after the last insert. This means that $i will be higher than the maximum key of $dish.

Some thoughts:

Any time you're testing for equality with null, you should consider using is_null (or !is_null). It is more accurate.

This:

$dish[$i]=$row['dishes'];
$i++;

Would be better as:

// obviously instead of $i you would use count($dish) later (oruseforeach)
$dish[]=$row['dishes']; 

That final while loop would be better as a foreach:

foreach($dishas$val)
{
    echo$val;
}

Solution 2:

You need to make sure the index exists before echoing it, as so:

while($j<=$i)
 {
     if (isset($dish[$j])) echo$dish[$j];
     $j++;
 }

Solution 3:

Your second while loop is going to far. You only define dishes up to i-1 and then you loop through it up to and including i. Change it to:

while($j<$i)
