i want to use if within while loop plz check it out and point out the mistake
$n=2;
$e=8;
$n=$e;
while ($n<=$e)
{
if ($n%2=0)
{
echo"result is " .$n
$n=$n+1;
}
else
{
echo "invalid";
}
}

i dont have a clue what is ment to happen here
but line 8 at the end needs a ;
explain why u need it anu i and other my be able to help
Your bracing and indenting is all over the place. Tidy it up! My fave, but other formatting poss:
$n=2;
$e=8;
$n=$e;
while ($n<=$e){
if ($n%2=0){
echo"result is " .$n;
$n=$n+1;
}else{
echo "invalid";
}
}
Now I can see that motters was right - add a ; at end of line 6
Why declare $n=2 on line 1 and then $n=$e on line 3?
I realize you are using "less than or equal to" in your for() loop but is it possible you're getting undesired output because you are reassigning $n? It seems redundant, at the very least.
And listen to ardav- formatting is a must, especially when you use the forums because it's harder for others to read sloppy code ;)
The problem is on line 6. You should write
if ($n%2==0)
instead of
if ($n%2=0)
From the other 'spots':
$n=2;
$e=8;
while ($n<=$e){
if ($n%2==0){
echo"result is " .$n;
}else{
echo "invalid";
}
$n++;
}
If you leave in the $n=$e, the loop will run once only as it is at the max permissible value (8).
If you have the incrementer ($n++ or $n=$n+1) inside the conditional structure, you will get an infinite loop once the value of $n is odd.
The above code should give:
result is 2
invalid
result is 4
invalid
result is 6
invalid
result is 8
I'm a little confused as to what the code is supposed to do.
